     7.     (C)     SUPPORTING FORCES:

          a.     Artillery:

               Artillery support for 3-22 Infantry during Operation Yellowstone II was provided by 2-77 Artillery.  At various times during the operation, the following batteries provided direct support for the battalion.

C Battery 2-77 Artillery (105mm)
A Battery 2-77 Artillery (105mm)
B Battery 2-77 Artillery (105mm)
1-27 Artillery (155mm)
               (e)     Additional fire support was provided by the Battalion Heavy Weapons Platoon in general support, while all weapons platoons provided direct support at company level.  All supporting artillery fires were extremely responsive and accurate.

          b.     United States Air Force:  Extensive effective use was made of Tactical Air to include preplanned and immediate missions.  All 3-22 Infantry requests for air support when through 3rd Brigade, 25th Infantry Division; this was accomplished by forwarding all requests to the Brigade Liaison Officer.

          c.     Army Aviation:

               (1)     Operation Yellowstone II began on 29 Dec 67 with a combat assault of 3-22 Infantry (-) into a cold LZ.  The LZ was prepared by artillery and gunships prior to the combat assault.  The 269th Combat Aviation Battalion provided 3 lifts of 20 ships to conduct the combat assault.

               (2)     Daily resupply and extraction sorties were flown by CH-47 helicopters.  A severe rotor wash problem existed because of the powder conditions of the soil at the FSB.  This problem was partially solved by the use of Pena Prime on two helipads at the FSB.

               (3)     On the morning of 2 Jan 68, during the Battle of Soui Cut, Army Aviation played a major role.  At 0330, an emergency resupply of Class V was resupplied to 3-22 Infantry (-) by 145th Aviation.  In addition, 25th Aviation, 187th and 188th Combat Aviation Battalions provided direct support with gunships and emergency resupply.

               (4)     During Operation Yellowstone II, 3rd Brigade Aviation Section provided OH-23's for the 3-22 Infantry on immediate and preplanned requests.  Maximum extensive use was made of these resources for Reconnaissance/Command Control of the maneuver elements.

     8.     (C)     INTELLIGENCE:

          a.     Intelligence concerning the battalion TAOR for Operation Yellowstone II was obtained from 25th Division G-2, 3rd Brigade S-2, 25th Inf Detachment, VR sightings, and past operations.

          b.     On the night of 1 January-2 January 1968, during the New Years truce, FSB BURT (XT5080) was attacked by elements of the 271st and 272nd VC Regiments.  Interrogation of POWs after the battle revealed that on approximately 25 December these two regiments moved from or through the Cambodian Salient to staging areas within several hours walking distance of FSB BURT.  On the night prior to the attack, movement was engaged outside the perimeter and the following morning two bodies were discovered with documents indicating they belonged to the 271st (one body was possibly identified as the Company Commander of C.16 Mortar Company, 271st Regiment).  This was the first indication that this unit was in the area.  The next night, the 271st, supported by at least two Battalions of the 272nd, attacked FSB BURT.  It appeared that the battle plan included four battalions attacking with two battalions in reserve.  Documents found on one body indicated that he was the Commander of the 2nd Battalion, 271st regiment, although positive identification was impossible.  A Hoi Chanh who rallied on 12 January 1968, stated he was a member of the 271st.  His company had been held in reserve and at 020400 hours they began withdrawing into Cambodia.  His unit later moved out of Cambodia to vicinity XT5191 where they were hit by a B/52 strike.  They then moved back into Cambodia (XT5691).

          c.     During the remaining period of Operation Yellowstone II, 3-22 Infantry experienced light enemy contact.  Intelligence reports during the later stages of Operation Yellowstone II indicated that the VC were planning to conduct major offensive operations during the TET holiday period.  It was assumed from those intelligence reports that the light contact we were experiencing was the result of the VC troop buildup in unknown staging areas.

                (2)     Development and Maintenance of Morale.

                    (a)     Throughout the duration of this operation, the Battalion “Regulars Club” was able to provide an adequate supply of cold refreshments.  This was accomplished by aerial resupply whenever the situation permitted.  There were very few occasions during the period that free beer and soda could not be supplied from the rear area.

                    (b)     Incoming mail was transported daily from Dau Tieng Base Camp to the forward area by air, during resupply.  Outgoing mail was transported daily from the forward area during extraction.

                    (c)     Catholic and Protestant religious services were conducted in the forward area by 3rd Brigade, 25th Infantry Division Chaplains.

          b.     Supply:  The logistical support for this operation was two-fold.  Class II and IV came from Dau Tieng, Class I and III came from Katum, with all resupply conducted by helicopter CH-47.

               The principal “Supporting Agencies” for the sources of resupply and services are as follows:

               (1) Battalion S-4, Dau Tieng

               (2)     Support Battalion (Prov) Dau Tieng and Battalion S-4 (FWD), Katum.

               Radio Set AN/PRC-25     2
               Mask, Protective M17     20
               Surgical Instrument Set     2

          f.     Communications:

               (1)     The proximity of the Battalion to Dau Tieng Base Camp did not permit the use of direct radio communications without the use of a retrans station, located at Nui Ba Den.

               (2)     Land line communications were established to FSB BURT and were highly effective; however, there were occasional breaks caused by APCs crossing the lines.  This problem was solved by either burying the cable or rerouting the lines around problem areas.

               (3)     In general, communications were excellent.  Terrain occasionally interfered with radio transmission; however, long antennas nearly always eliminated the problem.

                    (a)     Maximum personnel utilized by Battalion Commo Section at any one time during all phases:

                         1     1 Communications Officer

                         2     4 Wiremen

                         3     3 Radio Operators

                         4     3 Radio Chiefs

                         5     3 Radio Mechanics

                         6     5 Switchboard Operators

                         7     1 Generator Operator

                    (b)     Equipment used during all phases of operation:

                         1     3 292 Antennas

                         2     6 TA312 Telephones

                         3     (illegible) miles wire WD-1TT

                         4     (illegible) radio equipment

                         5     1 ¼ ton vehicle

                         6     1 Switchboard SB22

                         7     2 TA-1 Telephones

                         8     1 10KW Generator

                         9     2 Lighting Sets

          g.     Medical:

               (1)     The medical operation continued its three phase concept which consists of primary care by line medic at company level, referral to senior medic with command group and, finally, evacuation to Dau Tieng for more extensive care.

               (2)     In addition, an underground aid station staffed by two medical specialists and Battalion Surgeon was established at FSB BURT after the Battalion returned to that location on 7 January 1968.

               (3)     No medical problems were encountered during this operation.


     15.      (C)     COMMANDER'S ANALYSIS:

          a     Comments:  None

          b.     Lessons Learned:

               (1)     The well built bunker, using a deep foxhole with heavy overhead cover contributed to the ability of the positions to withstand mortar rounds, RPG hits and S/A fire.

               (2)     LPs proved to be a valuable asset in the detection of VC movement and activity.  Likewise, the AP could be utilized as a RECON element along with the ability to engage small enemy forces, thus disrupting much of the VC's plans and activities.

               (3)     The use of Pena Prime helped to reduce the dust problem on LZ's.  It proved of great value in landing, unloading and boarding of helicopters.

               (4)     Employing the 105mm (canister) in conjunction with the “Clock System” thus allowing the battery free traverse movement and being able to full cover the perimeter was of great help.  This allowed personnel time to construct defensive positions who otherwise would have been used to man the perimeter.

SUBJECT:     Combat Operations After Action Report

TO:          See Distribution:


     2.     DATES OF OPERATION:  7 December 1967 thru 24 February 1968

     3.     LOCATION:  War Zone “C”

     4.     COMMAND HEADQUARTERS:  3rd Squadron, 17th Cavalry (-)

     5.     REPORTING OFFICER:  Christopher B. Sinclair, LTC, Commanding


          A Trp, MAJ Nathan M. Pulliam, Commanding, 7 December 1967 thru 24 February 1968

          B Trp, MAJ Wayne T. Shehorn, Commanding

          C Trp, MAJ Gary E. Luck, Commanding, 16 December thru 24 February 1968

          D Trp, CPT Russell W. Mangal, Commanding

     7.     SUPPORTING FORCES:  None

     8.     INTELLIGENCE:

          a.     Prior to Operation, War Zone “C” is a historical enemy stronghold, it was known to have extensive base camps and large caches of ammunition, weapons and food.  Recent intelligence strongly indicated that COSVN headquarters, the combat elements in direct support of COSVN and at least one VC division were located in War Zone “C”.

          b.     Terrain and Weather.

               (1)     General:  The area of operation was bounded by the Cambodian border on the north, route TL22 on the west, the east/west grid XT63 on the south and the Saigon River on the east.  The AO encompassed the entirety of War Zone C.

               (2)     Terrain:  The area is flat to gently rolling, with two prominent features.  Nui Ba Den and the hill mass Hui Tha La and Nui Ong.  The terrain slopes from north to south, creating north/south patterns of movement, parallel to the stream flow.  Aerial observation is very good in the open southern third of the area and poor in the crescent of jungle along the Cambodian boarder.  Ground observation is poor due to dense vegetation.  Fields of fire in most areas are restricted by the vegetation.

               (3)     Weather:  The weather during Operation YELLOWSTONE was typical of the dry season.  The average temperature was 88 degrees and there was only one day of rain.  In the morning hours, fog reduced the visibility, conditions improved at approximately 0930 and continued to improve throughout the day.

          c.     Intelligence During the Operation.

               The area of operation contained important enemy base areas for logistical and command operations as well as a protected and concealed commo liaison and supply corridor between War Zone “C” and Cambodia.  Enemy units identified in the AO were 271st VC Regiment, 272nd VC Regiment and 141st VC Regiment.  The 1st Guard Battalion was also identified.  During Operation YELLOWSTONE, numerous bunker complexes were discovered which could have supported the above units.

     9.     MISSION:  Conduct operations in assigned areas in War Zone “C” with two air cavalry troops and one ground cavalry troop to find and fix the enemy; be prepared to secure route 4 from Tay Ninh to Katum; secure fire Support Base Soui Da from enemy attack; secure downed aircraft and dropped loads anywhere in the area of operations.

     10.     Concept of Operation:

          Maneuver - Operation will be conducted in two phases:

          Phase I:  Movement to Soui Da

          Phase II:  3-17th Cav will conduct recon in force with two air cavalry troops in assigned zones.  Trp D provides base camp security.  Squadron will be prepared to assist 1st Bde. 25th Inf Div in assigned AO to find and fix known enemy units.  Maximum effort in initial phases.  Limited night recon will be conducted.

     11.     EXECUTION:

          a.     Movement.  On 7 December 1967, the squadron (minus C Trp) moved by organic ground and air vehicles from Di An to FSB Soui Da (XT340583).  The Squadron Field Trains remained in Di An while the Combat Trains moved forward and co-located with the Squadron Command Post at FSB Soui Da.  The move was completed by 071800H December 1967.

          b.     8 December 1967 thru 16 December 1967.

               Operations during this period were characterized by a day and night program of armed visual reconnaissance with frequent insertions of the aerorifle platoons.  D Trp conducted reconnaissance in force operations within AO Soui Da and convoy escort between Tay Ninh and Soui Da.  As enemy mortar attacks increased in the vicinity of the FSB at Katum, the squadron was tasked to perform night counter-mortar security for the FSB.  This mission was hampered by the lack of a secure landing area at or near the FSB.  The squadron was forced to conduct the mission based out of FSB Soui Da, which increased the reaction time by 15 minutes and reduced station time to 1 hour.  Armed reconnaissance missions produced a constantly growing picture of the enemy situation.  It soon became evident that the initial intelligence estimate was correct.  Sightings of previously unlocated base camps were reported daily.  As each sub-area was searched in detail, large bunker complexes were located along every large stream in the jungle area.  Enemy lines of communication interlacing the fortified base camps were found and plotted, while many of the base camps were vacant and showed no signs of recent use.  A large percentage proved to be occupied and the aeroscouts were drawing automatic weapons fire on every mission.  During these initial stages of the operation, the squadron was averaging one aircraft hit per day.  Upon locating an occupied base area, all available fires were brought to bear on the target.  Aeroweapons immediately engaged the target, followed by TAC air and artillery adjusted by the aeroscouts.  As a composite picture of the enemy location became clear, B-52 strikes were programmed on the larger concentrations.  The squadron was soon requesting a B-52 strike a day with devastating results on the enemy.  At 0445 hours on 14 December 1967, following nightly probes and harassing fire, FSB Soui Da was attacked with small arms and RPG rockets.  This resulted in 2 US WIA, two aircraft damaged and one destroyed.  Fire was returned immediately and a sweep at first light revealed 1 VC KIA, 2 RPG rockets and 1 RPG launcher captured.  Operations continued as normal with no reduction in combat effectiveness as a result of the attack.  On 15 December 1967, while suppressing a mortar attack on the FSB at Katum, a B Trp UH1C was downed by enemy fire.  The aircraft crashed in the jungle amid 60 to 100 ft trees.  An OH6A of B Trp attempted to pick up the crew but was unable to make a safe approach to the area.  A second OH6A with a lighter fuel and ammunition load succeeded in reaching the downed gunships.  While extracting two crewmembers, the OH6A was also downed by enemy fire.  The surviving crewmembers formed a perimeter of defense and with the support of aeroweapons ships were able to hold off the enemy until a friendly ground force reached them and extracted them.  US losses were 2 KIA.  The following morning, B Trp aeroscouts and aeroweapons escorted elements of the 2nd Bn, 14th Inf into the area to secure the aircraft for extraction.  The scouts, preceding the infantry, counted 50 VC bodies.  On 16 December 1967, C Trp, which had been OPCON to the 199th LIB, reverted to squadron control and A Trp was released to the OPCON of the 199th LIB.  This changeover was conducted while continuing to accomplish both assigned missions.

          c.     17 December 1967.  C Trp aerorifles were inserted at Xt577357 to perform a Bomb Damage Assessment following a B-52 strike.  During the reconnaissance, enemy contact was made resulting in 1 NVA POW, 3 NVA KIA, 2 AK-47 and two 9mm pistols captured.  Assorted medical supplies and web gear were also evacuated.  Interrogation of the POW revealed that he was a member of a previously unidentified battalion which had just entered South Vietnam and had not yet been committed.  Based on this and other intelligence, the 25th Inf Div initiated operation CAMDEN with one Brigade.

          d.     18 December 1967 thru 1 January 1968.  The squadron continued its primary mission of armed visual reconnaissance; however, several major modifications were made in both the mission assignment and the squadron's mode of operation.  It was realized that portions of the initial mission were detrimental to the overall effectivness of the squadron; for example, in order to secure downed aircraft and dropped loads, it is necessary to provide continuous aerial coverage and, in most cases, insert an aerorifle platoon for ground security.  To accomplish the mission, the squadron is required to divert at least one air cavalry troop from their primary mission of reconnaissance, thus greatly reducing the effectiveness of the squadron in its primary role.  In some cases, when dropped loads were in isolated areas, an air cavalry troop would be diverted for a day at a time.  When this was fully realized, the 25th Inf Div released the squadron from that portion of the original mission statement.  At that time, it was also realized that the areas of operation assigned the squadron were too restrictive and that the squadron's capabilities were not being taken advantage of.  It was decided that, rather than assign areas of operation, the squadron should have a free reign throughout the division TAOR.  This was accomplished by placing a liaison team with each brigade command post to coordinate activities within the brigade's area of responsibility.  This close coordination allowed a more rapid dissemination of information and the brigades were able to react directly to information collected by the aeroscouts.  Within a short time, joint operations with aeroscouts and aerorifle elements leading the infantry units into previously located enemy areas and with aeroweapons supporting became commonplace.  As the units became accustomed to working together and the ground elements gained confidence in the credibility of the intelligence furnished by the aeroscouts and the accuracy of the fires of the aeroweapons, a smooth and efficient team came into existence.  This greatly increased morale as well as the efficiency of both elements.  The air cavalry elements became more enthused as they saw tangible results being produced from the reconnaissance they had performed.  For the ground elements, prior knowledge of what to expect and pinpoint location of the enemy lead to a number of successes.  Large caches were located and either destroyed or evacuated.  The enemy will not be capable of restocking the rice, weapons and ammunition lost in those sweeps for a considerable length of time.

e. 1 January 1968 thru 6 January 1968.  At 2400 hrs 1 January 1968, the
enemy broke the New Years truce by a multi-regimental attack on FSB Burt, XT499800.  Aeroweapons teams were immediately dispatched to help relieve the besieged infantry and artillery.  As the ammunition supply of the defenders grew short, it was decided that an aerial re-supply and reinforcement must be attempted.  To accomplish this, the 25th Inf Div pooled the lift assets of the 25th Avn Bde, D Trp of 3/4 Cav and B & C Trps of the 3/17th Cav under the command of the C Trp Commander.  The provisional airlift company moved to the FSB at Katum to await further missions.  An aerial re-supply of FSB Burt was accomplished and the provisional company was released to the parent units upon arrival of elements of the 269th Combat Aviation Battalion.  B & D Trp continued saturation reconnaissance of the area surrounding FSB Burt.  Movement was detected along two main routes of withdrawal and fire was brought to bear on the retreating enemy.  The scouts and weapons continued to engage the enemy until darkness afforded him a means of escape.  At the end of the day, the squadron had accounted for 26 VC KIA (BC).  Since most of the engagement was in dense jungle, it is reasonable to assume that the actual number was many times the body count.  At 022058 Jan 68, the enemy began a mortar attack on FSB Soui Da, a total of 11 rounds fell with no friendly losses.  At dawn 3 Jan 68, the aeroscouts picked up the trail of the retreating VC and continued the actions of the preceding day.  The northern escape route was traced to a regimental base camp complex in a dense jungle, vic XT556910, XT561910, XT555905 and XT561905.  Apparently, the VC had thought this area safe from detection and had planned to regroup and re-supply there.  Numerous air strikes were directed into the base camps throughout the day.  The artillery provided continuous fires between air strikes and throughout the night.  Resuming operations at first light on 4 Jan 68, a definite pattern of movement north towards Cambodia was detected.  Automatic weapons fire directed at the aeroscouts continued to be heavy as in the past three days.  Here again, the pattern was definitely shifting north.  On the 5th of January, groups of VC were detected moving north on the trails, carrying wounded.  A group of 11 VC were caught in the open at XT542902 and killed by aeroweapons elements.  One of the 11 was a messenger carrying a pouch of documents.  A platoon from the 4th Bn, 9th Inf was inserted to recover the pouch but came under heavy automatic weapons fire.  The aeroweapons covered the extraction of the platoon.  It was certain by this time that the remnants of the attacking force were fleeing north and into Cambodia.  Aeroweapons ships at high altitude were able to detect 3 battalion sized base camps and numerous smaller camps inside Cambodia in the “Fish Hook” area.  One of these camps overlapped the border and a B-52 strike was placed at XT535907.  A ground insertion at Xt533901 was attempted to follow up the strike but the enemy had not been weakened enough to allow the exploitation to be successful.  The aerorifles were pinned down by automatic weapons fire from bunkers surrounding the landing zone.  The lift returned and, under the cover of the aeroweapons platoon, successfully extracted the aerorifles.  The coordination of fires and teamwork enabled the aerorifles to be extracted with minimum friendly losses.  One UH1N was destroyed by ground fire; however, the crew suffered only minor injuries.

          f.     7 January 1968.  The squadron was ordered to close out FSB Soui Da and establish a new base at Tay Ninh.  While the distance to move was short, the move was to be conducted without a break in mission or a reduction in combat effectiveness.  The squadron combat trains moved in two phases.  The second element maintained full operational capabilities while the first displaced.  The entire operation went smoothly and the support of the combat elements continued.

          g.     8 January 1968 thru 30 January 1968.  The squadron continued to operate in the manner described in para d.  With the release from the mission of securing FSB Soui Da, more of the combat power of the squadron became available.  D Trp was able to conduct more extensive operations and began to conduct troop sized reconnaissance in force daily.  C Trp, in coordination with the 3rd Bde, inserted the aerorifle platoon on a daily basis.  The aerorifles would be inserted in blocking positions for the 2nd Bn, 22nd Mech.  After the units converged, the aerorifles would act as a point element leading the ground force into known enemy bases under the direction of the aeroscouts.  On 24 January, D Trp was released to the operational control of the 1st Bde and OPCON was further delegated to the 1st Bn, 5th Mech.

          h.     31 January 1968 thru 24 February 1968.  The squadron was diverted from Operation YELLOWSTONE to Operation SARATOGA.

          a.     Supply:

               (1)     Class I.  Daily average strength supplied from ration breakdown was 500 persons.  No problems were encountered.

               (2)     Class II.  Critical TOE shortages of communication equipment have not been solved.  Antennas for radio AN/ARC-102 are still short (10 ea), also 4 ea AN/VRC - 24 radios and 4 ea AU/PRC - 41 radios.  The three items mentioned above are essential for extending communication capabilities of squadron aircraft and would increase the mission capability considerably.

               (3)     Class III.  Support was outstanding throughout the operational area.

               (4)     Class IV.  Support of the squadron at FSB Soui Da was outstanding.

               (5)     Class V.  The following is the daily average expenditure and should be used as a planning figure in the future.


     M79 Grenade Launcher     215     49
     M5 40mm Grenade Launcher     12     387
     2.75 Rocket Systems     38     217
     7.62 All Types          112     26,230
     Smoke Grenades        --     50
     Mortar 81mm          3     19

          b.     Maintenance:

               Initially, the troop and squadron maintenance platoons were located with the squadron combat trains at FSB Soui Da.  It was decided early in the operation that this was an unsatisfactory location.  At least 50% of the aircraft maintenance must be performed at night.  Utilization of the aircraft maintenance lighting sets in a forward combat base is impossible due to light discipline.  It was decided that the maintenance platoons should be based in a more secure area.  On 10 December 1967, the platoons moved to and established a maintenance facility at Tay Ninh.

          c.     Treatment of Casualties:

               During Operation YELLOWSTONE, all serious casualties were evacuated directly to the nearest suitable hospital.  The success of this method is borne out by the fact this squadron has not had one casualty die of wounds subsequent to evacuation.


          The need for an organic aircraft mounted night-lighting device was realized during the operation.  The Squadron's ability to perform its mission at night is limited at this time.  The addition of an infrared device would increase the squadron's ability to interdict enemy movement and to provide close fire support during the hours of darkness.  The squadron obtained a Xenon searchlight to accomplish this; however, the necessary controls are not available in country.


          a.     ITEM:  Initial General Reconnaissance

               DISCUSSION:  The enemy's means of travel in the jungle is by trails.  Since all troop movements and re-supply take place on these trails, it is impossible to camouflage them completely.

               OBSERVATION:  When operating in an area for the first time, a general high recon should be made of the area to determine the trail pattern, direction of trails and trail terminal points.  This initial survey, when properly analyzed, will provide an excellent base of information on which plans for detailed reconnaissance can be formulated.

          b.     ITEM:  Aeroweapons Supporting Ground Units

               DISCUSSION:  Many times, ground commanders were guilty of faulty marking of friendly positions or giving confusing directions on the locations of enemy positions.

               OBSERVATION:  Due to faulty marking of friendly locations and confusing directions as to the location of the enemy, suppressive fire has been placed dangerously close to friendly ground units.  Ground commanders at all levels should be thoroughly familiar with the proper procedures of marking friendly locations.  It is equally important to stress the need for clear, concise instructions as to the location of enemy elements.

          c.     ITEM:  Use of Mirrors

               DISCUSSION:  Several operations have been conducted supporting small units.  In almost every instance, it has been necessary for the ground unit to positively identify its location.

               OBSERVATION:  Although smoke is an excellent means of marking the position, it reveals the location to the enemy on the ground as well as the friendly aircraft.  A few flashes from a signal mirror have proven equally effective, without revealing the friendly positions.  Panel markers have also been used effectively.

          d.     ITEM:  Aeroscouts Conducting Trail Reconnaissance

               DISCUSSION:  Aeroscouts have conducted extensive trail reconnaissance during Operation YELLOWSTONE.

               OBSERVATION:  It has been found that using slow air speed allows the enemy ample time to find concealment and, at a rapid speed, it is impossible to detect enemy personnel on the trail.  By flying at 60 knots and criss-crossing the trail, the scouts are able to detect enemy personnel and are relatively safe from ground fire.

          e.     ITEM:  Aeroscouts Screening for Ground Units

               DISCUSSION:  After contact has been made by a ground unit, the enemy increases his efforts to shoot down scout aircraft.

               OBSERVATION:  Once contact has been made, scouts should move to the flanks of the friendly unit and work to contain the enemy or canalize him by using artillery and air assets.

          f.     ITEM:  Baby Sitting

               DISCUSSION:  Air to ground communication with aeroscouts is very poor due to their constant use of “Nap of the Earth” flying techniques.

               OBSERVATION:  This problem has been solved by teaming an aeroweapons ship with the aeroscout, extending his communications range as well as providing the scout with heavy weapons protection.  This method, called “Baby Sitting” by the aeroweapons, has increased the efficiency of the aeroscouts by assuring them immediate support if downed by ground fire.

     7.     (C)     SUPPORTING FORCES:

          a.     Artillery

               (1)     Preplanned and on call direct and indirect artillery fires were used during the operation to cover enemy routes of advance and withdrawal.  Artillery was always available and was considered extremely effective and timely.  The use of direct fire artillery, 105mm HE and beehive and 155mm HE, proved to be particularly effective in holding enemy assaults at the FSB perimeter.  Artillery fire was initially used during the early stages of the attack, primarily in a counter-mortar role.  Preplanned counter-mortar targets were attacked by all firing batteries located at FSB BURT and FSB BEAUREGARD.  As the attack progressed and listening posts and ambush patrols located outside the perimeter reported contact with enemy forces, calls for indirect fire were received and delivered by the Artillery.  As it became evident that a full scale enemy attack was in progress, numerous calls for fire were received.  Adjust fire and preplanned defensive concentrations were fired.  At one point, the battery fire direction center of Battery C, 2nd Bn, 77th Arty reported handling 8 missions simultaneously.  Perhaps the most effective use of artillery was made in a direct fire role.  As the perimeter reported heavy contact, the artillery men leveled their tubes and, after coordination with Infantry elements, began delivering HE direct fire into locations just forward of the perimeter.  A large volume of direct fire was delivered around the entire perimeter during the battle.  Highly instrumental in stopping the enemy forces attempting to breach the perimeter was the use of the APERS (Beehive) round.  This fire was delivered to the northeast, southeast and southwest portions of the perimeter.  Particular volume was concentrated to the southeast and south down the road where large masses of enemy forces were attempting to penetrate.  During the middle and latter stages of the attack, effective use was made of blocking fires to the west by batteries from FSB BEAUREGARD.  These fires served a two-fold purpose in preventing not reinforcements but withdrawal in that direction.  As the enemy began withdrawing to the south, fires were placed along and just off the road in an interdiction role.

               (2)     Position Occupied:  FSB BURT (XT500 805).

               (3)     Statistical Data:

                         5     WB     -     -     100     -     -

          b.     USAF:

               (1)     Extensive use was made of tactical air immediate strike missions, with the normal air request channels being used for all missions flown.  Air strikes were employed in assembly areas and on heavy enemy attacking troop concentrations to within 150 meters of the FSB perimeter, utilizing all ordnance.  It is considered that napalm and CBU's were particularly effective in breaking the attack formations of the massed enemy.  Spooky was utilized to provide illumination for the air strikes and fire support during lulls between air strikes.  It is considered that Tac Air provided the overwhelming fire superiority that eventually broke the enemy attack.

               (2)     Statistical Data:

                    (a)     Missions:

                         1     Immediate missions requested:  32

                         2     Immediate missions flown:  32

                         3     Results of Tactical Air:  It is not possible to determine precise damage done to the enemy by air strikes due to the fact that the battle was fought in darkness and extensive use of all available weapons made exact determination of the cause of death of recovered enemy bodies difficult.  Though the enemy attack was halted by ground forces at the perimeter, Tac Air appears to be responsible for breaking the attack.  Though it is impossible to determine when fire parity was attained - superiority was gained by use of Tac Air.

          c.     Army Aviation:

               (1)     Extensive use was made of Army gunships.  Prior to employment of Tac Air, gunships provided close-in direct fire support to the perimeter.  Subsequent to Tac Air initiation, Army Air was utilized to provide interdictory fires on escape routes and direct fires on suspected enemy reinforcements moving toward the FSB from the north.  An Army Air flareship was used to great advantage during periods when Spooky was not available.  Additionally, gunships were utilized to escort resupply aircraft; their suppressive fires were absolutely necessary as the FSB was ringed with enemy anti-aircraft automatic weapons.

               (2)     Emergency ammunition resupply began at 020330 Jan 68 utilizing 5 Spartans (189th AHC) from Bien Hoa with ammunition for 2/22 Inf and 3/22 Inf.

               (3)     Five Spartans (189th AHC), Black Widows (188th AHC) and Little Bear (A/25th Avn) resupplied the artillery out of Katum.

               (4)     Following Army Aviation units participated in the battle:

                    (a)     UH-1D:  189 AHC (Spartans), 188th AHC (Black Widows) and A/25th Avn (Little Bear).

                    (b)     General Support:  C/3/17 Air Cavalry, 188th AHC (Black Widows), 187th AHC (Rat Pack), 189th AHC (Spartans), 25th Avn (Little Bears) and flare ship (Wildcat).

                    (c)     Ammunition was resupplied as follows:

                                   From Dau Tieng          From Katum

                         M-79     3374     1008

                         4.2          250     360

                         81mm     350     360

                         .50 cal     18000     40000

                         5.56          89600     65000

                         7.62          30400     13440

     8.     (C)     INTELLIGENCE:

          a.     Information concerning the Suoi Cut area for Operation Yellowstone (Continued) was obtained from 25th Division G-2 sources, 11 Field Force PERINTREP, visual reconnaissance missions and long range reconnaissance patrols.

               (1)     Northeastern War Zone “C” was being used by VC main force units as a safe haven due to the absence of friendly large scale operations in that area since the battle of Soui Tre in March 1967.

               (2)     Routes 244 and 246 were being used as main supply routes in northeastern War Zone “C” and into central Binh Long province.

               (3)     Units located in the area of Suoi Cut were believed to be two battalions of the 141st NVA Regiment with the possibility of a third battalion unlocated in the area.  Contact with these elements by the 1st Brigade, 25th Infantry US Division on 16 and 20 December in the vicinity of Katum and Bo Tuc confirmed the presence of this unit.  In addition, elements of the 271st VC Regiment were also believed to be located in the vicinity of XT3976.

          b.     Enemy Activity:

               (1)     During the month of December, enemy activity took the form of counter-sweep activities against elements of the 1st Brigade, 25th US Infantry Division in the vicinity of Katum and Bo Tuc.  In addition, friendly base camps in that area received mortar attacks almost nightly.

               (2)     The cessation of friendly H and I firing during the New Year's truce brought about increased enemy activity in the vicinity of Suoi Cut and from this activity evolved the heavy mortar and ground attack on FSB Burt (XT 500 807).  It is quite obvious that the enemy planned to use the cease fire to move his troops safely to within striking range of the FSB.

               (3)     Readouts of captured enemy documents and interrogation of PW's indicate that the entire 271st VC Regiment and the 5th and 6th Battalions, 272nd  VC Regiment were employed in this attack.

               (4)     The attack of FSB Burt took the form of what appeared to be harassing mortar fire into the FSB during early evening hours.  As the evening progressed, ambush patrols began observing increasing movement at various points completely encircling the perimeter of the FSB.  At approximately 2100-2200 hours, ambush patrols began receiving “probing attacks” which developed into heavy contact by small enemy elements.  At approximately 2230 hours, mortar rounds (both 60mm and 82mm) and RPG rounds began “raining” into the FSB from a number of enemy mortar sites and RPG positions around the periphery.  The mortar attack was followed immediately by a ground attack of small arms, automatic weapons, grenades and rifle grenades completely encompassing the base.  The brunt of the attack was placed first in the southeast sector while a secondary attack was directed at the northwest and northeast sectors.  The attack from the southeast shifted to the south and then back to the southeast.  The attacks continued throughout the night, terminating at approximately 020500H.  At this time, the enemy began withdrawing to the south and southeast and to the northeast.

     9.     (C)     MISSION:  3rd Brigade, 25th Infantry Division moves to northern War Zone “C” and conducts offensive operations to destroy VC/NVA forces & installations, opens land lines of communications for friendly forces and interdicts VC/NVA lines of communications.

     10.     (C)     CONCEPT OF OPERATION:  3rd Brigade, 25th Infantry Division defended FSB Burt with one Infantry and one Mechanized Infantry Battalion.  Positions were dug in and listening posts were established by each line platoon.  Ambush patrols and listening posts were established by each line company.  Two batteries of 105mm and one battery of 155mm howitzers supported the defense utilizing indirect fires and fully integrating direct fires.  (References:  OPORD 40-67, HQ, 30 Bde, 25th Inf Div, with changes 1 and 2 dated 26 Dec 67; FRAGO 1-67 to OPORD 60-67, dated 27 Dec 67.)

     11.     (C)     EXECUTION (Chronological Summary)

          a.     01184Jan 68:  An ambush patrol made contact with an unknown sized VC force 200 meters east of the perimeter.

          b.     012010H Jan 68:  Movement noted around the perimeter with light enemy probing or patrolling actions directed toward the perimeter.  (illegible) mortar attacks directed toward the FSB.

          c.     012330H Jan 68:  FSB Burt (XT 500 805) came under heavy mortar attack followed by RPG, SA and AW fire mostly from the southeast and northwest, although all sectors of the perimeter were subjected to all types of fire.  A light fire team, FAC and Tac Air, in addition to Spooky and Arty were called for and employed as they became available.  All of the six ambush patrols became engaged to varying degrees.

          d.     012400H Jan 68:  Mortar and RPG fires slackened and ground attacks were launched against the perimeter from all directions with secondary attacks coming from the northwest and northeast.  The main VC effort came from the southwest and shifted to the southeast.

          e.     020100H Jan 68:  VC elements had succeeded in reaching bunker line positions in the south (C/2-22 Inf (M) ) and southeast (C/3-22 Inf).  Beehive artillery rounds were employed along with direct fire artillery and gun and flare ships.  Local battalion reserves were committed to secure the perimeter.  An additional reserve of two provisional infantry squads was reconstituted from Headquarters elements of the 2-22 Inf and committed in support of the 3-22 Inf in the southeast.

          f.     020145H Jan 68:  VC fire and contact slackened.

          g.     020200H Jan 68:  VC fires increased and all areas were engaged.  Weight of attack was to the south (C/2-22 Inf (M) ) and southeast (C/3-22 Inf).  Once again, beehive and direct fire artillery was employed along with ground and flare ships.  The south and southeast portions of the perimeter were under pressure of the heaviest attack.

          h.     020248H Jan 68:  Tac Air is employed in the south, allowing additional artillery to be placed in other areas of the perimeter.  Army air support continues.

          i.     020311H Jan 68:  Fire and contact slackens and ceases except in the south and southeast where Tac Air is being employed.

          j.     020327H Jan 68:  All VC efforts are directed at the south and southeast portions of the perimeter with only sporadic fires directed to other portions of the FSB.  Artillery direct and indirect fire, beehive, gun and flare ships and tactical air continues to be employed.

          k.     020500H Jan 68:  VC begin withdrawal to south and southeast and to the northeast, leaving delaying forces to screen their movement.  All available fires continued to interdict withdrawal routes.

     12.     (C)     RESULTS:

          (a)     US Losses:

               (1)     Personnel:  23KHA, 146 WHA.

               (2)     Equipment:  3 APC's, 1 40mm gun (SP) destroyed.  2 APC's moderate damage, 1 cal .45 pistol, 3 .50 cal machine guns, 9 M-60 machine guns, 14 M-16 rifles, 3 M-79 grenade launchers, 1 starlight scope, 1 sight 81mm mortar.

          (b)     VC Losses:

               (1)     Personnel:  379 KIA, 8 POW (WIA).

               (2)     Enemy equipment captured and evacuated:  75 AK-47 rifles, 11 Chicom LMG's, 1 cal .45 pistol; 12 RPG-7 launchers, 16 RPG-2 launchers, 2 TA-1 telephones and 5 lbs documents.

               (3)     Enemy equipment destroyed:


50 Chicom grenades     2 miles electrical wire     100 sets web gear
180 RPG rockets     72 canteens     12 pistol belts

2 rds 75mm recoilless     56 entrenching tools     7 ponchos

4000 rds AK-47 ammo

1000 LMG ammo

10 propellant charges
RPG 2 and 7

30 AK-47 magazines

     13.     (C)     ADMINISTRATIVE MATTERS:

          a.     Personnel:  During the engagement, the Brigade S-T section operated from Camp Rainier with reports being forwarded from forward locations.

          b.     Supply:  Notification to be prepared to effect emergency resupply of Class V from Katum to FSB Burt was received by the Brigade S-4 at approximately 020130H at Katum.  It was determined that all aircraft would be controlled on the Brigade Admin and Logistics frequency.  Units being resupplied were 2/22 Inf (M), 3/22 Inf and 2/77 Arty.  Aircraft were controlled by the Brigade S-4 for resupply of 2/22 Inf and 3/22 Inf.  Aircraft utilized by 2/77 Arty were controlled by S-4, 2/77 Arty sharing the same frequency.

          c.     Medical:  Medical evacuation of wounded personnel from FSB Burt was accomplished initially by resupply aircraft and subsequently by dustoff crews stationed in Dau Tieng and Tay Ninh with backup coverage providing secondary evacuation by ships from Cu Chi and Long Binh.  The primary routes of evacuation were:  (1) D Company, 25th Medical Battalion located in Katum, (2) B company, 25th Medical Battalion in Dau Tieng, and (3) the 45th Surgical Hospital located in Tay Ninh.  Secondary evacuation was accomplished to the 12th Evacuation Hospital, Cu Chi, the 24th and 93rd Evacuation Hospitals in Long Binh, as well as emergency cases to the 45th Surgical Hospital.


     15.     (C)     COMMANDERS ANALYSIS:  NVA forces encountered during this engagement appeared to be well disciplined and were very well equipped, including new weapons.  The success of the defense is attributed to the determination of the individual soldier, superior infantry firepower, devastating artillery fire, beehive, direct & indirect fires, and decisive, overwhelming tactical air power.  The ground defenses were deliberate and mutually supporting and, while still being fully developed, were adequate to meet the threat posed the night of 1-2 January 1968.

     16.     (C)     RECOMMENDATIONS:

          a.     The integration of direct artillery fires in the defense of a FSB is a primary consideration.  Planning of perimeter installations must include overhead and rear protection to permit its uninhibited employment.

          b.     Ambush patrols are vital to providing information as to enemy courses of action.  AP's should be constituted in sufficient strength to protect themselves, but not so large as to be unable to take evasive action while continually reporting enemy information.

          c.     Tac Air can be used very effectively at night.  A visible reference point is absolutely necessary in vectoring Tac Air onto precise target areas.

          d.     Spooky illumination is necessary for Tac Air; however, should be delayed until the last possible moment prior to employing Tac Air as it illuminates defensive installations to the advantage of the enemy.  Once the Tac Air starts, the enemy's advantage provided by the illumination is negated by the fires from the aircraft.

 Operation Yellowstone-2/22nd Infantry


     9.     (C)     INTELLIGENCE:  Intelligence received during Operation YELLOWSTONE proved to be timely and generally accurate.  During much of this operation, the Bn CP was located close to the Bde CP, facilitating quick exchange of intelligence information.  The Bn interpreters proved a great asset in initial interrogation of PWs and initial readout of captured documents.  Greater use could have been made of STAR, RED HAZE, and PEOPLE SNIFFER missions to aid in detecting the buildup and movement of enemy forces.

     10.     (C)     MISSION:
               (1)     2nd Bn (Mech), 22nd Inf moved to Northern War Zone “C” to conduct offensive operations to destroy VC/NVA forces and installations, open land lines of communication for friendly forces and interdict VC/NVA trails and routes.

               (2)     From 1-24 February, 2-22 Inf (M) provided Base Camp Security for Camp Rainier, cleared Hwy 239 and 26 between Tay Ninh and Dau Tieng daily, then secured the convoy and conducted Reconnaissance In Force in areas adjacent to Camp Rainier.

     11.     (C)     CONCEPT OF OPERATIONS:  On 27 Dec 67, 2-22 Inf (M) moved from Camp Ranier to Prek Klok, Katum and Bo Tuc, arriving and establishing, in conjunction with 3-22 Inf, Fire Support Base BURT on 31 Dec 67.  Until 27 Jan 68, in conjunction with Fire support Base security, 2-22 Inf (M) conducted operations north to the Cambodian border and to the south a distance of about 10 km.  On 28 Jan 68, 2-22 Inf (M) departed FSPB BURT en route to Camp Rainier, arriving at about 2230 hours, 31 Jan 68.  From 1-24 Feb 68, 2-22 Inf (M) conducted Reconnaissance in Force from Camp Rainier while, at the same time, providing Base Camp Defense.

     12.     (C)     CHRONOLOGICAL SUMMARY:

          a.     General:
               (1)     27 Dec 67:  At 0048, all elements of the 2-22 Inf (m) had closed into Camp Rainier.  At 0834, 2-22 Inf (M) began to move enroute to Prek Klok, XT275786, to initiate Operation YELLOWSTONE.  At 1540, 2-22 Inf (M) became OPCON to 1st Bde, 25th Inf Div.  At 1540, 2-22 Inf (M) had closed into Prek Klok, where they laagered for the night.

     14.     (C)     ADMINISTRATIVE MATTERS:

          a.     Personnel:  The influx of new personnel has improved in recent weeks, and throughout Operation YELLOWSTONE, no major personnel problem areas existed.
          b.     Routine Reports:  No difficulty.
          c.     Supply:  There were no problems encountered in support of operational units during this period.  Supply for the month of January was effected from a forward support base at Katum, and also Dau Tieng, with timely and efficient coordination.  After the Battle of Suoi Cat, some delay was experienced in receipt of 40mm ammunition to replenish the battalion basic load.
          d.     Maintenance:  limited availability of major assemblies such as power packs, transmission and transfer cases continue to present a major problem in the maintenance of M-113 Armored Personnel Carriers.
          c.     Treatment of Casualties:  (Evacuation and Hospitalization)      
               (1)     Evacuation of personnel was accomplished in a highly efficient manner and no problems existed in this area.
               (2)     Identification of deceased personnel, although greatly improved, is still posing some problems, which can be eliminated by position action taken in battle areas:
                    (a)     Responsible personnel at the site of evacuation insure that all personnel evacuated are properly tagged.
                    (b)     Responsible personnel at Field Hospitals receiving evacuated personnel should not relay information to inquiring agencies pertaining to the identity of evacuees until positive identification is determined in the manner outlined in existing regulations.
                    (c)     Continual command emphasis that each individual soldier possess and properly wear and carry identification tags and cards, in addition to marking of boots, belts and headgear as required by current regulations.
               (3)     Some difficulty was experienced in location of personnel by the parent unit after evacuation from the field.  Hospitals are not notifying units when patients are received, thereby causing units to contact various field hospitals by telephone to determine the location of patients.
          f.     Communications:  Communication throughout Operation YELLOWSTONE was excellent due to outstanding support from the Division Signal Maintenance agencies.


     16.  (C)     COMMANDER'S ANALYSIS:

     Operations in War Zone C during this period were characterized by light contact with the exception of the Suoi Cut Battle.  The VC/NVA personnel contacted during this period also seemed to be green and untrained as evidenced by several weapons captured that had never been fired and were relatively new.  Also noted were random groups of VC/NVA personnel who were wandering about seemingly disorganized and with a complete disregard for the use of cover and concealment.  It is felt that all key personnel had displaced to the south and that the remaining stragglers were either replacements or rear-area type caretaker personnel.
     Also noteworthy was a complete absence of newly emplaced mines or booby traps in the area of operations.  All mines located were several months old and many had become uncovered by erosion.
     Operations around the Dau Tieng base camp and adjacent to the NSR from Dau Tieng to Tay Ninh were characterized by an increase in harassment of the convoy route and in an intensified mine and booby trap effort in this area.  It is felt that this harassment was coordinated to complement the Tet Offensive effort to canalize in mobile units to the road net, to weaken our forces by attrition at little cost to himself, and to restrict the deployment of personnel and equipment from Dau Tieng to support operations in the south.  The best counter action to the enemy's design is to continue and increase, if possible, the temp of offensive sweep operations in order to break out of regular patterns of dependence upon road networks.

          (1)     Artillery Support for month of May:  Appropriate exchanges of artillery liaison officers were made between the 25th Inf Div Arty and units of the 25th Inf Div (ARVN) on a permanent basis.  This facilitated clearance of fires and provided U.S. arty support for ARVN units.  Also, the 25th Inf Div Arty assumed responsibility for artillery fire support of RVNAF units within CU CHI District.  This allowed sufficient ARVN 105mm pieces to be released from static defense to form a mobile battery in support of combat operations.  The U.S. artillery support for Operation MAILI was phased to support the above mission.  Upon completion of Operation MAILI, a rapid reaction 4.2 inch mortar platoon was deployed under operational control of the 25th Inf Div Arty to demonstrate the division's capability to provide rapid reinforcement to any pacified area threatened by the Viet Cong.  During Operation WAHIAWA, the artillery support (light, medium and heavy) was used to assist in the destruction of a major logistical base of the VC.  Use of indirect 155mm fires in direct support of infantry advancing in heavy undergrowth proved effective in this operation.

          (2)     Artillery support for month of June:   The 25th Div Arty continued development of support for units of ARVN.  Defensive fires were increased for the 7th Regt of the 5th Div (ARVN).  Of 2200 rounds fired in support of ARVN forces, 400 rounds were fired in 15 missions to support small outposts.  Operations of the month consisted primarily of single artillery batteries supporting individual infantry battalions on pacification missions.  The direct support battalions worked with an ASR if 20 rounds for this period with no serious degradation of capabilities.  In addition to normal U.S. support, one special mission, Operation FIREBALL, was undertaken.  A 25th Inf Div Arty Task Force consisting of one 105mm battery (B/2/13th Arty,  II FFORCEV unit), one infantry company (B/4/9th Inf) and a command group from 3/13th, were deployed to a remote area of TAY NINH Province.  The task force provided artillery support for a province force employed in establishing a CIDG campsite.

         (3)     Artillery support for month of July:  The 25th Div Arty continued to provide artillery support to RVN units within effective artillery range of CU CHI Base Camp.  Artillery support was also provided to RVN units at BAO TRAI, DUC HUE, DUC HOA and TRANG BANG from forward artillery positions.  Beginning 12 July an artillery denial program was undertaken in the FILHOL Plantation to counter increased VC activity in that area.  During the period two “FIREBALL” Operations were   (p12)  conducted.  The mission of these operations was to lend direct artillery support to a CIDGSF Camp in a remote area north of TAY NINH City.  Operation FIREBALL  I which began 21 June, was successfully concluded on 15 July.  B/2/13th Arty from II FFORCEV was detached from the 25th Div Arty.  Operation FIREBALL  II commenced on 25 July, when a task force consisting of a command group from 1/8th Arty, B/1/8th Arty (-), and B/2/14th Inf were airlifted to a remote area north of TAY NINH City.  FIREBALL  II was concluded on 29 July.  
          The success of both FIREBALL operations is demonstrated by the fact that no serious VC activity was encountered during the periods when the artillery task forces were in the area.  During July, Operations MOKULEIA and KOKO HEAD required direct artillery support over the major portion of HAU NGHIA Province.  To accomplish this, three provisional four-gun batteries were formed from the 1/8th  Arty with a six-gun battery remaining at CU CHI Base Camp.  C/1/8th Arty (-), was airlifted to TRUNG LAP Ranger Camp on 20 July and 23 July to support one day infantry operations in the area.  The unit was air extracted each day.  On Operations KAHANA I & II, 7/11th Arty (-) moved by convoy to the XUAN LOC-GIA RAY-VO DAT area to support S&D and pacification operations of the 1st Bde, 25th Inf Div.  The 25th Div Arty fired 37706 rounds of artillery the evening of 26 July, and the morning of 27 July in counter mortar fires for defense of the CU CHI Base Camp.  During the quarter, 26,048 rds of artillery were fired.  Results by artillery were 117 VC KIA (BC), 325 VC KIA (poss).

     d.     Other Combat Support:   Results of Air Forces strikes were 85 VC KBA and 156 KBA (poss), from 1264 air sorties.  There were 21,397 army aviation sorties during the quarter.

     e.     (FOUO)   Chemical:

          (1)     Perimeter Defoliation.
          (a)   During the period 26 June - 5 July, the Division Chemical Section provided technical supervision to division troop units for the dispersal of 2, 4-D Defoliant on the perimeter of CU CHI Base Camp.  At the same time, under the supervision of the Brigade Chemical Officers, the 1st and 2nd Bdgs defoliated their portions of the perimeter.

          (b)   The mixture used was two parts diesel and one part 2,4-D.

          (c)   Method of dispersion was the use of the M106 Portable Riot Control Agent Dispenser (Mity-Mite) loaded on a vehicle.  In areas that could not be traversed by vehicles, the M106 was back-packed.  The most effective vehicle utilized was the M113 Personnel Carrier since it was able to penetrate areas untenable to wheeled vehicles.
          (d)   The operation was considered effective in those areas covered by defoliant.  A total of 22 barrels were dispersed.  Subsequent evaluation of this operation indicates that an insufficient quantity was dispersed by this method to cover the entire perimeter and recurring applications will be required to defoliate new growth.

          (2)   CS Seeding of XOM MOI Woods

          (a)   On 11 July the mission of the Division Chemical Section was to seed an area along the road through the XOM MOI Woods (XT608174 to XT615165) with Riot Control Agent CS.

          (b)   The mission was carried out in the following manner:
               1.  The CS was to be dispersed in package form from four M113 APC's provided by A/3/4 Cav.
               2.  Two 8 pound bags of CS were tied together with heavy twine forming a 16 lb package of CS.  A blasting cap with ¼ lb of C-4 and a 45 second time fuse was used to explode the bags.  The blasting caps, time fuse, and fuse lighters were carried in a separate APC from the C-4.  Upon arrival at the target area the detonators were assembled and placed between the CS bags;  a piece of tape was used to secure the charges.

               3.   The APC's were lined up four abreast at fifty meter intervals.  The platoon leader acted as controller for the drop.  One package was to be dropped from each of the APC's every 50 meters;  the command to drop being given by the platoon leader.

               4.   At the command, drop, one man in each APC held the package while a second man pulled the fuse lighter pin.  The first man then dropped the armed package out the ramp door of the APC.

          (c)   This method of dispersing CS proved to be very effective.  By this method, large areas can be seeded in short periods of time, and use of the APC, affords personnel a great deal of protection.

     f.    (C)     Intelligence:

            (1)     VC Activity.

(a)  May 1966

      1.   (C)   During the month of May, enemy activities were characterized by acts
of harassment and sabotage directed against friendly operations, the CU CHI Base perimeter, and movement on National Routes 1 and 22.  Incidents involving anti-aircraft fire and mines increased during the month.  This is attributed to the increase of friendly operations.  There was also a marked increase in the number of reports concerning large numbers of VC moving in the area between Route 1, the HO BO WOODS, and BOI LOI WOODS.  A mortar attack on a forward CP occurred 27 May, when the fie support elements of the 1st Bde CP received 20 rounds of 60mm mortar fire.


               2.   (C)     The majority of the VC actions involved forces of platoon or smaller size.  However, there were two incidents involving VC forces of company size.  On 3 May, an ambush patrol from C/1/27th Inf was attacked, vic XT5640446, by a company composed of local guerrillas and elements from the 506th LP Bn.  On 7 May, a patrol from B/1/5th (M) engaged elements of the 403rd Co, 320th LF Bn vic XT505316.     

               3.   (C)     The VC lost large quantities of rice, cloth and medical supplies as a result of friendly operations conducted during May.  In addition, the VC were forced to abandon base camps and supply areas.  VC movement on supply and liaison routes, was again hampered by friendly operations, patrols and aerial observation.

               4.   (C)     With the advent of the rainy season and increased combat activities by U.S. and ARVN forces, the VC will be hard pressed to replace the rice and medicine lost as a result of Operation WAHIAWA.  Due to the number of KIA's suffered by the VC and the large amount of ammunition lost, the combat effectiveness of the VC units in the division TAOR have been a reduced considerably.  The losses could disrupt VC plans for operations in the early stages of the monsoon season.

               5.   (U)     Results of all operations during May 1966 were:

                                     VC KIA (BC)        211          Small Arms     41
                                     VC KIA (poss)     372          Rice          901.8 tons
                                     VCC                        13          Other edibles     619 tons
                                     VCS                        57          Cloth          98,698 yds
(b)  June 1966

1.   (C)     During the month of June, VC activities continued to be characterized
by  acts of ;harassment and sabotage directed against friendly units, the CU CHI Base perimeter, and movement on LOC's within HAU NGHIA Province.   The number of anti-aircraft incidents doubled from those reported in May, while mining incidents decreased from the previous month.  The large number of AA incidents can be attributed to increased heliborne activity in connection with friendly operations.  During the month of June, agent reports, CHIEU HOI reports, and SPAR activity indicated that the VC had returned to the HO BO WOODS area.  Operation “COCO PALMS” conducted by the 1/5 (M) Inf during the period 25 June - 1 July confirmed these reports.  Documents captured indicated that elements of the SAIGON - GIA - DINH Special Region Committee were located in the extensive tunnel system in the area.  There was a sharp decline in the number of reports of large numbers of VC moving in HAU NGHIA Province.  Numerous reports continued to be received during the month concerning large VC units moving into the BO LOI WOODS area from the vicinity of MICHELIN Plantation.

               2.   (C)     The majority of enemy activity during the month involved forces of platoon size or smaller.  The VC continued to withdraw when contacted in force by friendly elements.  There were numerous significan contacts which  captured


or killed an entire VC guerrilla platoon.  The final count was 11 VC KIA (BC) and 19 captured.  The capture of 19 marked one of the largest single captures of VC in the III Corps Area.  The VC suffered another serious setback when C/1/5 (M) discovered a large weapons cache on 7 June.  The cache, which included 105 small arms, was one of the largest arms caches discovered by Free World Forces in Vietnam, and was the first time Russian ammunition had been captured in any large quantity.  Another significant action occurred on 7 June, when elements of the 2/27 Inf discovered a grenade factory which was capable of producing 400 to 500 grenades per week.  The month of June also marked the first time the VC utilized the RPG-2 grenade launcher with successful results.  The action took place on 18 June, when A/!/5 (M) Inf encountered an unknown size VC force in a heavily fortified position in the FILHOL Plantation.  The VC utilized the grenade launchers to damage 3 APC's and inflict casualties on the occupants.

               3.   (C)     Division operations continue to force the VC to abandon base camps and supply areas.  His movement is becoming more restricted as a result of the division's pacification operations throughout HAU NGHIA Province.  The presence of US forces has motivated the civilian populace into offering information concerning VC activities in the area.  This information has not only led to the discovery of weapons and ammunition, but in a few cases, several VC have been apprehended as a result of information provided by fellow platoon members.  The presence of US forces has also hampered VC movement on supply and liaison routes.

               4.   (C)     The enemy's loss of supplies and war materiel during the month has been detrimental to his war effort.  With many of their supply routes interdicted, the resupply of war materiel will become more difficult.  The loss of a possible headquarters in the HO BO WOODS area could have an effect on the command and control of VC Forces in the HO BO WOODS, and the destruction of their extensive tunnel system could force the VC out of an area they have long considered a safe haven.  Harassment of US base areas will continue, and the enemy will continue to seek targets of opportunity.  Although the loss of war materiel and base areas have disrupted their plans for the monsoon season, the VC can be expected to take advantage of increasing periods of inclement weather to conduct their harassing tactics.

               5.   (U)     Major VC Losses during the month:

                                        VC KIA (BC)       133          Small arms     250
                                        VC KIA (poss)     326          Heavy weapons         2
                                        VCC                        73          Rice          217.4 tons
                                        VCS                      233

          (c)     July 1966


                            1.   (C)     During the month of July, VC initiated activity increased within the 25th Division's TAOR, and other areas in HAU NGHIA Province.  An increase in harassing and probing incidents and actual assaults on RF and PF outposts were noted in the entire 31st DTA.  The number of anti-aircraft incidents increased by approximately one third from those reported in June, while mining incidents decreased approximately 75%.  The large number of AA incidents can be attributed to wide use of Eagle Flights during friendly S&D operations.  There was an increase in the number of reports from various sources concerning the movement of large numbers of VC throughout HAU NGHIA Province.  These movements of VC forces were reported most frequently in the vic of BAO TRAI (XT526044), DUC HUE (XT440057), and DUC HOA (XS597966).  These three towns were consistently reported as targets for VC attacks to take place on 20 July, Geneva Accord's Day, and on 26 July.  
          The reinforcement of BAO TRAI  by 25th Div elements, plus the numerous air-strikes and artillery missions fired in the immediate vicinity were believed to be instrumental in deterring the attack plans of the 506th LF Bn, and the 267th Bn DT2 Regt in the HAU NGHIA Provincial capital area.  The attacks were believed to be planned in conjunction with the mortar and recoilless rifle attack on the 25th Div Base Camp on 26 July.  The reactions to the mortar attacks on PHUOC HIEP and the TRUNG LAF Ranger Training Center, plus the encounter with the 1st Bn, 165A Regt on 19 July, were also believed to have prevented a larger scale attack on the division base area.  It is also believed that the artillery fire in response to the TRUNG LAP mortar attack deterred a possible attack on the training center.

                               2.   (C)       There were numerous incidents of significant enemy contact during the month.  The most significant action was the 75mm recoilless rifle and 82mm mortar attacks on the division base camp on 26 and 27 July.  There were indications that elements of the Z41st  Arty Bn, U80 Arty Regt. Had taken part in the attack.  This heavy weapons unit normally supports VC main force regiments in the War Zone C area.  Another significant action took place on 19 July when elements of A/1/27 Inf were airlifted into two objectives on the edge of the HO BO WOODS and immediately engaged elements of the 1st Bn, 165A Regt.  The VC, who in some cases wore camouflaged uniforms and steel helmets, maintained continuous contact with friendly elements for 4 ½ hours using mortars, grenades, SA and AW.  The length of the encounter indicated once again that the VC will fight tenaciously when surprised or forced to fight in their base areas.
          The 165A Regiment also figured prominently in the 19 July attack in the PHUOC MIEN outpost located on Route 1, nine kilometers northwest of CU CHI.  This action demonstrated the VC capability to strike quickly with a superior force and rapidly withdraw when confronted by division reaction forces.  Concurrent with the attack on PHUOC HIEP, the VC also fired 40 - 50 rds of 82mm mortar into the TRUNG LAP ARVN Ranger Training Center, resulting in friendly losses of 3 KIA and 14 WIA.  This clearly demonstrated the capability of VC main force units to successfully conduct simultaneous attacks on separate targets.  Large quantities of VC arms and ammunition continued to be located by friendly forces, the most significant being an arms factory located by C/2/27th Inf on 19 July, near the ORIENTAL River at XS513988.  The FILHOL Plantation and HO BO WOODS, in spite of their proximity to the base camp, constant harassment by artillery, and frequent S&D operations, continue to be the scene of occasional intense fighting.  Aircraft flying over these areas are routinely subjected to AA fire, and ground elements continually encounter mines, booby traps, and VC fortifications.  Many of the firing positions utilized during the 26/27 July attack on the base were located along the southern edge of the FILHOL Plantation.

                            3.   (C)     The VC continue to be forced from their base and supply areas.  VC activities are also becoming more restricted because of our numerous operations in various areas of the HAU NGHIA Province.  Operation CHECKMATE which is designed to deny to the VC the clandestine use of major LOC's in the area, is also having an impact on VC supply and liaison activities.  The presence of US forces continues to motivate the local population into offering information concerning VC activities in the area.  Numerous arms/weapons caches have been located during the month as a result of this information.  There are indications that the VC no longer feel secure in villages and hamlets which they once controlled.  This is in part due to the rapid reaction by division elements in responding to agent reports, and information provided by voluntary informants.  Another example of diminishing VC influence is reflected in the number of refugees during “Operation EWA”.  A total of 353 persons requested evacuation from a VC controlled area in DUC HUE District west of the ORIENTAL River, and were accommodated by aviation elements supporting the 2nd Bde.  The mortar and recoilless rifle attack against the division base area will undoubtedly be exploited by the enemy for propaganda purposes in an attempt to reassert their former position of influence among the people.  Harassment of outposts, roadblocks, and general VC activity will probably increase during August and the VC may attempt another attack on the base camp or one of the district capitals.

                        4.   (C)     VC personnel and equipment losses 1 -31 July 1966:

                                        VC KIA (BC)       194          Small arms      49
                                        VC KIA (poss)     434          Rice          36.9 tons
                                        VCC                       53
                                        VCS                     181
          (2)   (C)     Counterintelligence:


          (a)     The major emphasis in counter-intelligence during the reporting period has been the identification of VC infrastructure in the TAOR, and the detection and neutralization of the VC espionage and sabotage effort against the 25th Infantry Division.  The major counter-intelligence project presently underway by the division is called Operation KLEEN.  This program involves screening and investigation of approximately 1000 Vietnamese laborers employed daily on construction projects in the base camp.  Most of these laborers have been under VC domination for several years, and are therefore susceptible to both active and passive collaboration with VC agents.  It is also recognized that these laborers form a pool of potential informants who might for mercenary, retaliatory or opportunistic motives collect information for us concerning VC activities in their village and hamlets.  Since the most logical assessors of this potential among the work force are the US military supervisors and interpreters, these people are briefed and debriefed on a continuing basis by CI agents of the 25th MID.  The first phase of Operation KLEEN, which was to photograph the ID cards and other identity papers of all indigenous laborers, has been completed and it is now estimated that the files are 95 percent complete allowing for new arrivals and those absent when the ID cards were photographed.


          (b)     This file will be utilized to check against National Police files, comparison against black and gray lists, and screening by local and provincial MSS officials and sources to detect false ID papers, and to identify known or suspected VC.  This file will also provide information concerning the number of persons from the various villages in the area, and groups in each village and hamlet in our area.  It is hoped that by continuation of this positive CI effort we can minimize the espionage and sabotage threat to the base camp while continuing the practice of employing indigenous help in non-critical areas.

          (3)     (C)     Checkmate:


          (a)     On 6 July, the division initiated a program of establishing check points at random locations along major highways in HAU NGHIA and TAY NINH Provinces.  The purpose of this operation called CHECKMATE, is to deny the VC the use of land LOC's to covertly move personnel and equipment through our TAOR.  These check points are manned by elements of the 3 /4 Cav, CI agents of the 25th MI Det, and National Police.  The Cav. Element provides security for the area utilizing 4 -  5 armored personnel carriers and occasionally a tank, depending on the area security situation.  Two checkpoints are then established approximately 150 meters apart enabling traffic checks in two directions.  Two National Policemen and one CI agent normally conduct the screening process at each location.  The   3/4 Cav aero- rifle platoon is also prepared to assist the roadblock element if necessary and aerial scouts search out the surrounding area for other targets of opportunity which might warrant the relocation of the ground element.

          (b)     Twelve CHECKMATES were conducted in July and a total of 2,007 vehicles and 7,665 persons screened.  Results of these operations include 4 VCC, 19VCS, 7 draft dodgers, and 14 people of National Police interest detained.  Numerous contraband items of CHICOM and CAMBODIAN manufacture were also confiscated by the police.

          (4)     (C)     Long Range Reconnaissance Patrol 1 (LRRP):


 During the period a Div LRRP of 3 officers and 38 EM were organized, manned and equipped.  The patrol was attached to the 3 /4 Cav for support and placed under the AC of S, G2 for operational control.  A cadre was chosen from the initial volunteers and sent to NHA TRANG  for approximately 3 weeks training with the 5th Special Forces Group.  Upon return to base camp additional training was conducted by the entire patrol with emphasis on operating in 5 man teams.  To date, the patrol has conducted four patrols in HAU NGHIA, TAY NINH and LONG KHANH provinces with the mission of locating VC base camps and detecting VC movement.  The patrol has proven itself a valuable addition to our intelligence acquisition capability.

          (5) (FOUO)  Liaison:     

The G2 section, in order to insure that all intelligence information  originating in HAU NGHIA Province is made available to the OG of the 25th Div, has greatly increased its liaison with adjacent and subordinate US and ARVN intelligence agencies.  In addition to daily visits to HQ, 5th Inf Div (ARVN), HQ, 25th Div (ARVN), and the province capital at BAO TRAI, personal liaison is also maintained with the sub-sector HQ's in our TAOR, the TRUNG LAP Ranger Training Center, and the Special Forces Det's.  On numerous occasions during the reporting period, perishable information was received during one of these liaison visits enabling a rapid and effective division response.  It is anticipated that this closer contact with those agencies will improve the intra-province intelligence flow to the benefit of all concerned.

     g.  (FOUO)     Logistics:


          (1)   Supply and Services:

          (a)   During the quarter, the supply and services within the division generally improved.  All personnel have received an issue of jungle fatigues and boots.  The remainder of the new family of radios materially assisted in communications and reduced the previous high deadline rate of unit radios.  The Division also received the new light vehicle retrievers (M578), over 300 anti-intrusion devices and 600 shotguns.  With the assistance of Saigon Support  Command, the construction of prefabricated refrigerators has established a satisfactory static refrigeration capability.  On 1 June, 4800 cubic feet were completed, 9000 cubic feet were available 1 July, and 14000 cubic feet were com0pleted by 1 August 1966.  The ice cream plant completed 28 June has operated successfully and increased morale throughout the Division.

          (b)   By 31 July, the Class III yard was 85% completed.  Twenty of the 35 berms required for the 10,000 gallon collapsible storage tanks had been completed.  These berms proved effective during July when they absorbed mortar and recoilless rifle shrapnel and prevented serious damage to tanks and loss of fuel.

(2)  Maintenance:


  (a)   During the quarter, the division deadline rate was well below the average Army
standard rate with the exception of engineer (general and heavy equipment) and aircraft.  However, the July flyable rate was above Army Standard.

          (b)   The Red Ball system has been responsive with the execution of certain engineer heavy equipment and HHE items.  In these cases, Red Ball often runs over 30 days.  There has been little noted change in the over-all supply system.  Maintenance is becoming dependent upon the Red Ball system with little increase in the available ASL attacks.  In the aircraft field, the lack of receipt of requisitioned PLL and stockage items forces undue reliance on the Red Ball system.  This in turn decreases tactical helicopter availability.  If the zero balance trend continues as reflected during this quarter, and the initial deployment stockage is deleted, the deadline rate of all equipment will increase and create additional dependency and demands upon the Red Ball system.
          (3)   Transportation:   A total of 431 convoys were run between SAIGON and CU CHI with a total volume of 22,538 vehicles.  The last cargo of operations NOONLIGHT arrived in the base camp area on 3 June 1966.  This completed the movement of equipment and accompanying supplies of the Division units.  The 1st Log Comd provided assistance in the movement of POL products and for some operational ammunition.  The remaining cargo was transported from LONG BING and SAIGON with unit transportation.

          (4)   Operations:   In order to meet requirements within a responsive time frame, a “Forward Support Command” was established during the brigade size operations.  In operation WAHIAWA and KAHANA, all classes of supply were furnished at the brigade train sites.  Elements of a forward maintenance company, a medical company and the supply and transport battalion were attached to the brigade.  Both air and wheel convoys were successfully utilized for resupply.  These forward operations centers proved to be the solution for complete resupply when a unit operates away from base camp areas.

     h.   (FOUO)  Administration:


           (1)   Personnel:   During this period the personnel posture of the division has been excellent.  The present for duty strength, both officer and enlisted, currently exceeds the authorized strength.  There is a shortage of infantry NCO's (MOS11B40) in the grades of E5 and E6.  The casualty rate of NCO's has created a shortage in greater proportion than the rate of fill.  This shortage is recognized as an Army wide problem, and is not considered as a critical shortage.  The lower grade replacement fill in enlisted combat MOS's has been excellent with the exception of field artillery crewmen, MOS 13A10, and pioneers, MOS 12A10.  The fill on these two MOS's has been accelerated during the month of July substantially reducing shortages in Division Artillery and the 65th Engineer Battalion.  During May and June 1966, the division    had a shortage of single engine, single rotor observation helicopter mechanics, MOS 67M, and single engine, single rotor turbine utility helicopter mechanics, MOS 67N.  This shortage still exists.  However, through an OJT program and an exceptionally good rate of fill during July, the shortage is no longer considered critical.  The division has received an adequate number of company grade infantry officer replacements.  In fact, at the present time there is a slight overage in infantry captains.  As of 31 July 1966, the division was short 9 company grade artillery officers.  There is an officer grade imbalance in the division aviation battalion in that the battalion has only 40% of the authorized warrant officer aviators and 200% of the authorized commissioned officer aviators.  Some commissioned officers are filling warrant officer slots.  However, the aviator infusion program being conducted in Vietnam will assist in reducing this problem.

          (3)     Subordinate units have been assigned CA responsibility for seven separate villages or hamlets.   Additionally, the 1st Bde supports the 49th Regt (ARVN) and the 2nd Bde sponsors all 25th Inf Div (ARVN) units at DUC HOA and BAO TRAI.

          (4)     MEDCAP II:   The division MEDCAP program is directed towards medical and dental treatment, improvement of sanitary standards, operation of first aid stations, dispensaries, small hospitals, and training of indigenous personnel in first aid, sanitation, and other medically related fields with an aim towards eventual assumption of many of the medical duties by the Vietnamese themselves.  MEDCAPS are conducted in the assigned areas of CA responsibility twice a week.  During the reporting period 310 MEDCAPS provided medical treatment to 18,927 patients.

          (5)     Helping Hand:   During the reporting period the Helping Hand storage point became fully operational.  The 350 tons of Civic Action material donated by the citizens of the state of HAWAII have been stored.  On three occasions involving the support of hundreds of refugees, Helping Hand was able to respond rapidly and effectively.  To date Helping Hand items consisting of health and sanitation items, toys, clothes, educational materials and basic work items have been distributed to 26,839 needy villagers.

          (6)     A standard Helping Hand solatium box has been developed to be given to personnel and their dependents who are accidentally killed or injured under any circumstance by US forces.  It is also given to dependent survivors of victims of VC terrorist attacks.  The box is relatively standard with its contents tailored by sex and age of the recipients, and includes such items as rice, food, mild, clothing, toys, shower clogs, etc.

          (8)     The division held its first meeting of the Division Friendship Council in CU CHI during the first week of July.  It was attended by division officers, VC District Chief and his staff, American sub-sector advisors, and the ast-province USAID representative.  Items discussed included security communications, enlargement of regional and national police station and joint work on road repairs.  Additionally, personal friendship---------------------                               
          (9)     A Disaster Relief SOP was drafted during the month of July which standardizes procedures for treatment of VN civilians who sustain accidental injury or death as a result of action by US forces.  This SOP provides for medical evacuation, claims assistance, and solatium for the individual.

          (10)     A major effort in English instruction is taking place each week with an English education program sponsored by all subordinate units.  Instructional material was obtained from JUSPAO and classes are purposely kept small to increase the quality of learning.

          (11)     The division has conducted four specific operations designed and tailored for pacification purposes.  On these operations, a reinforced infantry battalion was located in an insecure area for a three to four week period.  The purpose was to use joint US - Vietnamese civic action and limited combat operations to improve the security of the area while providing Vietnamese officials an opportunity to explain to the people the policies and intentions of the government.

          (12)     The division conducted three County Fairs during the quarter in villages controlled by the VC.  The division band conducted a concert which was enthusiastically received.  The VC cultural team also entertained the villagers with songs and stories.  These teams continually prove to be very popular.  The people were well treated and in addition to the entertainment, they were fed and given a MEDCAP.  (App 13, Div Reg 525-1, Country Fair Operations.)

     j.     (FOUO)   Psychological Operations:


          (1)     A total of 90 hours of airborne loudspeaker support was provided by the 146th PSYOP Co.  Forty-two vehicular loudspeaker missions were conducted in coordination with the division PSYWAR effort.  Operational Activity has shown a steady increase each month as the division implemented its PSYWAR plans.

          (2)     A portable loudspeaker frame with four speakers on each end of the frame is being developed for use on helicopters.  An adapter assembly for power input, is being fabricated by electricians of the 3 /4 Cav.  The adapter will consist of a male and female plug to accommodate otherwise incompatible fittings, and enable the broadcast system to utilize standard 28 volt outlets in the UH/ 1 & OH/23 aircraft.

          (3)     While PSYWAR plans call for more activity in all fields, emphasis will be to increase loudspeaker missions.  It is felt that the advantages of the loudspeaker approach merit this new emphasis.  Literacy rate and area coverage are problems often encountered with leaflet drops, but not with loudspeaker missions.

          (4)     CHIEU HOI ralliers continue to provide an excellent source of tactical and psychological information.  At the request of the CU CHI CHIEU HOI Center, Division PSYWAR branch has supplied the center with several thousand National Safe Conduct Passes, and CHIEU HOI leaflets.  Enemy propagandists have come up with the VC equivalent of our CHIEU HOI appeal, heralding the benefits for those who rally to the National Liberation Front, and assuring them of good treatment.  When notification is received that a rallier has been received, the PSYWAR section attempts to interview the rallier as soon as possible.  A Polaroid photograph is taken, a tape recording made, and all applicable information noted.  The photographs taken will be used as part of the leaflet.  The tape recording can be played almost immediately over airborne loudspeakers.  When exploitable evidence is obtained, it may be used to produce tapes, add leaflets at division level, or it may be forwarded to the 246th PSYOP Co.  Since these ralliers are good sources of propaganda, the direct support PSYOP unit is requested to produce these leaflets on a priority basis.  Maximum time allowed on these priority requisitions is 48 hours.  Local facilities are used when time is more important than quantity or professional preparation.  Local Vietnamese officials are used as often as possible to record tapes and sign leaflets.

     k.   (FOUO)     Medical:


          (1)     Personnel and Supporting Medical Units.

(a)   The division at the end of the report period was short eight MC officers, one officer,
and one MSC officer.  The MC shortages were in the two Brigade Surgeon slots, and six slots within the 25th Medical Battalion.  We now have seven MCs on orders with four arriving in August, two in September, and one in November.  At present, we have a KA (Surgical Team consisting of three MC officers) team from the 68th Medical Group attached to the 25th Medical Battalion.

                       (b)   The 40th Dental Detachment (KJ) consisting of 12 Dental Corps Officers, one MSC Officer, and 20 enlisted men became operational at CU CHI on 23 May 1966.

                       (c)   The 7th Surgical Hospital became semi-operational on 31 July at CU CHI.  X-ray, surgical, and a 30 bed holding capability now exists.

(2)   Aero-medical Evacuation:

(a)   On 11 July 1966, a liaison visit was made by the 25th Aviation Battalion S-2 to the
Medical Company (Air Ambulance) (Prov) in SAIGON.  The purpose of this visit was to discuss the high incidence of ground fire in the 25th Inf Div TAOR.  It was learned that the medical unit does not maintain a ground fire chart, and  since it is a logistical organization, it is not in the normal intelligence distribution channels.  Therefore, the primary emphasis during the visit was directed toward familiarizing the unit commander and operations officer with our entire TAOR.  The best routes, LZ's and areas to avoid were covered in detail.  Areas where enemy ground fire must always be expected were posted on the unit operations map for further reference.  Arrangements were made that future liaison visits between units would update these areas as information became available.

          (b)   On 28 July, two classes were conducted by the Medical Company (Air Ambulance) (Prov) at CU CHI.  The classes included the techniques and capabilities of the air ambulance unit and demonstrations of new equipment.


          (3)     Preventive Medicine                                  

          (a)   Disease:  The spectrum of disease has not varied significantly.  The rainy season to date has had no impact on the incidence of malaria, with only one case occurring.  Six cases of infections hepatitis hae been diagnosed including four from HHB, 3rd Bn, 13th Arty.  No reservoir for this cluster of cases has been determined, but a number of personnel within the battery have been prophylactically inoculated with gamma globulin.  The VC rate has continued to increase during the three months from 230/1000 men/yr to 260/1000 men/yr, to 280/1000 men/yr.l  Heat injury has not been a problem.  The average of five cases per month is minimal.  Two cases of immersion foot were reported in May and none since.  A survey of disease of the feet indicated that no severe problem exists within the infantry units.

          (b)   Inoculation of animals against rabies is a monthly recurring program averaging approximately 20 animals.  However, most animal bites and scratches occur from monkeys and rats which have not been inoculated against rabies and number  5/month.

     l.   (C)     Signal:

          (1)   (U)   May:   During the last week of May, the 2nd Sig Group assumed responsibility for the lateral communication between the 25th (US) and15th (ARVN) Divisions, relieving the 125th Sig Bn of the task.  The 232nd Sig Co of the 2nd Sig Cp supplied both equipment and operators.

          (2)   (U)   June:   On 7 June 1966, the 25th Infantry Division MARS Station ABBAJ commenced operation in the LMARS network, RVN.  Operating on 1388.5  kes, “phone patch” service is available to MARS Hawaii on a 5 day week basis,  Tuesday through Saturday.  This service is available to all members of the 25th Infantry Division, with priority to WIA confined in hospital wards.

          (3)   (U)   July:   A New Equipment Introductory Team visited the division during the first two weeks of July to provide instruction on the Voice Cipher Device TSEC KY-8.  They qualified a repairman and an instructor from the Division Crypto Section in addition to qualifying approximately 80 operators.  During the first part of July, arrangements were completed to rebroadcast AFRS Vietnam at CU CHI.  The programming was transmitted from SAIGON over one voice channel on the VHF, and rebroadcast at 1330 kc from a 50 watt transmitter on a temporary antenna beginning 7 July.  The station operates 24 hours a day with 5 minutes of 25th Infantry Division News being broadcast at 2105 hours.

          (4)   (C)   During the last half of July, the Division Signal Office worked with the signal officer of the 196th Inf Bde, made liaison visits to Corps and Army signal sections, and to the 1st Sig Bde to obtain necessary radio frequencies call-signs to incorporate the 196th Bde units into the Div SOI.   Arrangements were also made to have the 1st Sig Bde provide base camp signal support to the 196th Bde because of the lack of signal resources within the 196th Bde, and the 125th Sig Bn.

     m.     (C)   Training                                       

          (1)   1 -31 May 1966:     Normal replacement and refresher training was conducted at small unit level by all units.  Infantry units emphasized platoon level training and classes on detection and destruction of VC mines and booby traps.  1st Bde, 25th Inf Div also received training from the 2nd Bde on ambush techniques and tunnel search and destroy procedures.  A/3/4 Cav trained on low-level aerial reconnaissance techniques.  Training in night flying techniques continued to be conducted by the 25th  Avn Bn and 3 /4 Cav in preparation for night airmobile operations.  A “Lightning Bug” team of aircraft with searchlights and cal .50 machineguns has been developed by the 25th Avn Bn to interdict waterways at night.  Combat support units have been given instruction on basic defense measures to allow them to reinforce the base camp perimeter.  This allows more combat troops for major unit operations.

          (2)   1-30 June 1966:  Due to the training of pathfinder personnel, the airmobile capability of this division was improved.  Night airmobile capability was expanded to include night combat assaults.  Night firing techniques were emphasized in all phases of training.  Special classes were conducted for generator operators.  Cross-training of support troops in infantry duties was accomplished so as to relieve more maneuver elements for operations.  Construction was initiated on two ranges for individual and crew served weapons.  Replacement training was expanded.  Training of the Long Range Reconnaissance Patrol was completed on 30 June.

          (3)     1-31 July 1966:   Refresher training emphasizing fire adjustment, communications, booby traps and mines, and counter-ambush techniques continued throughout the month.  A special training program was initiated to train selected individuals in mess management, military justice, explosives and demolitions, motor, signal and weapons maintenance, land flame thrower operations.  Aviation units continued training on formation flying and night airmobile techniques.  During this period the Lightning Ambush Academy began operations.  Located in the northwest sector of the 25th Inf Div base camp, the Ambush Academy facilities were completed on 13 July 1966, and formal instruction began on 15 July 1966.  The academy's staff and facilities can accommodate three TOE rifle platoons concurrently, and provide billet and messing accommodations for both students and cadre.  The academy's staff consists of a captain commandant, 2 lieutenant instructors, and 12 assistant instructors, and administrative personnel.  All instructors are combat veterans highly skilled in the conduct of ambush and counter-ambush techniques.  The four and one-half day course trains the rifle platoon in ambush techniques emphasizing all available lessons learned.  Normal attachments to the platoon such as forward observers and medical-------

3.   (C)     Commanders Observations and Recommendations:                        

     a.  Observations.

          (1)     Personnel.     None
          (2)     (G)   Operations:

ITEM:     Stay Behind Ambush.

DISCUSSION:     The employment of a squad sized or larger element as a “Stay Behind” force has proven to be most effective after a company or battalion departs an area of operations.  The VC will habitually move into an area after a unit departs to follow that unit or scavenge the area.

OBSERVATION:   “Stay Behind” ambush techniques have proven to be especially valuable after a unit has occupied an area for a period of 24 hours or more.  A “stay behind: ambush should be positioned by a unit prior to its departure from an area of operations.

ITEM:     Employment of “Picket Stations” (small blocking forces).

DISCUSSION:     The “picket stations” are small elements (fire team size) that are spaced throughout an operational area or along roads and trails to observe, direct fire, and interdict enemy LOC's.  The key to the successful employment of the “picket station” is knowing the enemy situation, and excellent communications.

OBSERVATION:   The utilization of “picket stations” provides excellent results in observing the VC, killing the VC, and controlling villagers.  It also enables an infantry battalion to cover a large area with fire, and to prohibit VC efforts to move or escape.

ITEM:     105mmHowitzer Battery'

DISCUSSION:     Mobility limitations in RVN dictate use of “light” maneuver forces which are deployed into operational areas by helicopters.  A substantial number of successful airmobile operations were conducted during the period employing four-gun 105mm howitzer batteries.  In addition to providing adequate fire support, a four-gun battery can be lifted in approximately one-half the time required to move a six-gun battery.  Howitzer crews can be rotated within a battery as the situation dictates, and the two remaining howitzers can be effectively employed to defend the base camp or provide fire support for squad or platoon size patrol operations, near the base camp.

OBSERVATION:   The four-gun 105mm howitzer battery with limited mission. Essential equipment can provide fire support to the maneuver battalion in airmobile operations.

             ITEM:     Counter-mortar Defenses:                                       

DISCUSSION:     To adequately counter a mortar attack requires a plan that will achieve wide coverage.  A small volume of fire on many locations is preferable to a large volume of fire on a small number of locations.  This can best be achieved by laying artillery by platoons on pre-planned targets.  4.2 inch and 81mm mortars can be profitably integrated into the early counter-mortar fires.  In the event an attack is mounted, all tubes fire fuse VT at likely locations.  As the situation develops and hostile positions are detected, the volume of fire in these areas are increased.  Counter-fire planning must also take into consideration possible enemy withdrawal routes.

OBSERVATION:   Counter-mortar plans should provide for instant broad coverage in the initial phase of a hostile mortar attack.

ITEM:   Shell WP.

DISCUSSION:     Experience has proven that close adjustment with shell HE is dangerous.  Maneuver elements often mistake their true location on the ground, and maps in some areas have been found to be inaccurate.  Firing with WP on initial rounds reduces the probability of friendly casualties, and allows air and ground observers to quickly spot their rounds.  If HE is to be fired, in effect it is advisable to complete the adjustment with HE since weight difference between projectiles will normally cause HE to fire as much as 75 meters beyond WP.  Adjustment with WP is also necessary when adjusting in dense vegetation.  The use of WP during periods of unfavorable humidity and wind conditions should be controlled to prevent limiting visibility

OBSERVATION:   The use of WP in adjustments should be included in SOP's, and FC's should be specifically trained on its use.

ITEM:   Ammunition Lots:

DISCUSSION:   Several lots of ammunition will normally be on hand in a battalion.  In firing, it has been found that variations in range between lots will often exceed 100 metes.  This variation becomes critical if a lot change is effected when firing defensive concentrations close to friendly troops.

OBSERVATION:   Lots used in adjusting defensive concentrations must also be used to fire for effect.

ITEM:   Air-Ground Communications.

DISCUSSION:   Experience has shown that FM radios installed in light observation helicopters at times encounter difficulty in communication with ground stations employing the new series of FM radios.  This situation can be off-set if the aerial observer carries an AN/PIC-25 radio set.  Better communication with the aircraft radio will result if the ground station sets squelch control in the “old squelch off” position.


OBSERVATION:   Aerial observers should always be equipped with the AN/PRC 25 radio set.     

ITEM:   Field Fortifications.

DISCUSSION:   “Digging in” become impractical in many areas during the monsoon season.  Adequate protection requires that bunkers be constructed above the surface.  When loading for a move, consideration must be given to space allocation for shoring and bunker construction materials.  Additional vehicles may be necessary in order to transport the proper amount of materials that are needed to adequately fortify a position.

OBSERVATION:   Procurement of fortification materials and the means of hauling them must be considered well in advance of operations, especially during the monsoon season.

ITEM:   Helilift of 105 Howitzer Battery:

DISCUSSION:   Movement of 105mm howitzer batteries overland during the monsoon season is frequently impossible.  Roads are impassable and suitable positions, of which there are few in number, are often accessible only by air.  105mm howitzer batteries must therefore develop proficiency in air movement.  Each 105 battery should have a complete set of rigging equipment.  By fully preparing loads in advance, a lift can be completed with minimum delay thereby permitting much more efficient aircraft utilization.  Training of personnel in path-finder techniques will also promote a more efficient airlift operation.

OBSERVATION:   All 105 howitzer batteries should be equipped with helilift rigging gear, and specialized pathfinder training should be given to selected personnel.

ITEM:   Use of mechanized forces for search and destroy operations.

DISCUSSION:   During search and destroy operations, two techniques are used, both of which are satisfactory.  The first method has the APC's on line with the infantry mounted.  A mounted sweep through the area is conducted followed by a second sweep dismounted.  During the second sweep, the infantry and the scouts dismount and search individual huts, tunnels, and other hiding places.  Each suspect area is thoroughly cleared and/or destroyed before moving to the next location.  In the second method, the tracks are again placed on line, but they move forward at the pace of the infantry in a manner similar to that for operations in built-up areas.  This dismounted infantry and scouts ferret out the enemy as the seep moves forward.

OBSERVATION:   Of the two techniques, the former seems more satisfactory.  This method costs fewer lives because of the armor protection against mines and booby traps.  Additionally, the initial sweep provides a valuable reconnaissance of the area.  This permits a concentration of infantry effort during the dismounted search, the time committed to search and destroy operations.


ITEM:   Truck - Infantry Team Employment:                             

DISCUSSION:     The VC make maximum use of anti-personnel mines and booby traps.  Whenever possible, tracked vehicles should lead dismounted infantry.  Tracked vehicles are less susceptible to damage and tend to hold personnel injuries to a minimum by exploding booby traps and mines with a minimum of exposure to personnel.  Track commanders must be alert to booby traps and command mines suspended from trees, while the following infantry must stay for enough behind to avoid being injured when detonation occurs.

OBSERVATION:   That tanks and APC's preceded infantry on operations through areas where enemy AP mines and booby traps are expected.

ITEM:   Road Obstacles:

DISCUSSION:  The VC often establish booby trapped and mined road obstacles.  Aerial observers can detect and locate such obstacles so early movement of the clearing force would ensure uninterrupted movement of the main body.  In clearing the obstacles, the surrounding area should be secured to insure that the roadblock is not covered by enemy fire.  The area should then be checked for the presence of command detonated mines.  If nothing is found, caution must still be exercised and only the minimum essential personnel should reduce the obstacle.

OBSERVATION:   To insure uninterrupted flow of traffic the following procedures should be followed:

                (1)    Use aerial observers to detect road obstacles.
(2)    Dispatch a clearing force.
(3)    Secure the area around the obstacle.
(4)    Check for command detonated mines.
(5)    Check for mines in the obstacle.
(6)    Use minimum personnel to reduce the obstacle.
(7)    Make maximum use of earth moving equipment when available.

ITEM:   Long Range Reconnaissance Patrol (LRRP) techniques for entry into an area of operations.

DISCUSSION:     It is essential to preserve secrecy in placing the LRRP into an operational area.  Landing by helicopter at last light and entry by foot march have been used.  The former has been the least successful technique unless the LZ was at a distance from the operational area, and located in an area of little VC activity.


OBSERVATION:   To insure undetected entry, fast march is favored for the final approach to the area of operations.

ITEM:     The necessity for employment of the air cavalry troop's maintenance and recovery helicopter on all unit missions has proven to be of paramount importance.

DISCUSSION:     In order to make timely assessment of damage incurred to aircraft and to assure prompt repair or evacuation, it is highly desirable to have the maintenance aircraft on station, and employed in its primary role when a troop mission is taking place.  It is very unrealistic to utilize the maintenance and recovery aircraft as a troop carrier backup, and expect it to function effectively in its primary role.  Damaged aircraft assessments are accomplished rapidly, and the helicopter is either flown out or expeditiously evacuated in order to reduce vulnerability to enemy actions.  Having this aircraft readily available during operations also increases the capability to immediately evacuate wounded personnel.

OBSERVATION:   The use of the maintenance and recovery helicopter assigned to the maintenance section of the troop should be confined to its primary role.

ITEM:   The use of OH aircraft in the aerial reconnaissance role is effective and reduces the valuable flight time of armed helicopters.

            DISCUSSION:  The use of light scout (OH-23) for reconnaissance and surveillance missions is     
            realistic and effective.  The tendency has been to utilize the armed UH-1B helicopter in observation
            roles because of its greater survivability in the event it is fired upon.  Limitations on the OH-23 are
            ineffective armament sub-systems, low survivability, and incompatibility of the old and new series of
           radios .

OBSERVATION:   Increased use should be made of the light scout aircraft (OH-23G) of the air cavalry troop for reconnaissance.

ITEM:   Road trafficability during the monsoon season.

DISCUSSION:   Units have experienced difficulty with trafficability on secondary roads and within operational base areas.  This situation was not experienced prior to the monsoon season.  This problem is normally encountered with vehicles carrying supplies such as ammunition, repair parts, barrier materials and similar items.  Trafficability can be increased to a great extent by squad location and ----------and equipment among organic vehicles.


ITEM:   Combined Combat Support Coordination Center (OSCC).

DISCUSSION:   A OSCC, jointly operated by ARVN and US personnel, was recently employed by the 25th Inf Div during the period 3 9 June 1966.  The OSCC functioned well, and contributed to mutual understanding between US and ARVN forces.  Rapid reaction to various situations was made possible by close and continuous ARVN - US coordination.  In the planning phase of joint operations, consideration must be given to the physical layout of the OSCC facilities.

          (1)     Billeting of ARVN personnel must be a responsibility of the headquarters setting up the OSCC.  Because the ARVN is short of equipment, US personnel must make every effort to be good hosts and provide comparable facilities for them.

          (2)     ARVN personnel should be briefed on the area surrounding the DTOC to include all facilities and specific location of guards.  Guards in turn should be briefed on the number of ARVN personnel in the area, and when they work and sleep.

     (3)     US personnel should, whenever possible, escort their ARVN counter-parts to meals to preclude any misunderstandings.

OBSERVATION:   Consideration given to the above will eliminate misunderstandings and promote a much more efficient and harmonious working relationship between US and ARVN forces.

ITEM:   Attached airmobile company.

DISCUSSION;   On extended operations, the attachment of the same airmobile company for the duration of the operation would eliminate repeated orientation of the crews on enemy and friendly dispositions.  In addition, mutual confidence and training would be greatly enhanced.

OBSERVATION:   In allocation of airmobile assets, consideration should be given to attaching the same airmobile company to a unit for the duration of their operation.

ITEM:   Joint utilization of tactical assets.

DISCUSSION:   The confidence and professionalism of ARVN has been markedly improved by providing them with resources to react to current intelligence, i.e., tactical air, artillery, and army aircraft.  Frequently the brigades will release their assets to the RVN for short periods of time in order for them to conduct limited operations.

OBSERVATION;   This technique must be exploited in order to insure continued ARVN participation in pacification efforts.


ITEM:   Early identification and coordination with supporting airmobile units is essential to proper aviation planning and the satisfactory execution of airmobile operations.

DISCUSSION:   The identification of supporting non-divisional airmobile companies is frequently delayed until the evening before a scheduled combat operations.  Such delays precipitate numerous unnecessary problems in coordination, planning and execution of airmobile operations.

OBSERVATION;   Supporting non-divisional airmobile companies should be identified a minimum of 18 hours prior to an operation.

            ITEM;  Air traffic congestion:  The control of all air traffic in the objective area in an airmobile assault     
is vested in the Air Mission Commander.

DISCUSSION:  Repeated instances of unauthorized aircraft intruding into the objective area during an airmobile assault continues to cause collision hazards to aircraft participating in the assault.  These aircraft interrupt or delay supporting fires, and result in the unnecessary maneuvering of assault aircraft.

OBSERVATION;   The flight of observer aircraft into the objective area of an airmobile operation must be coordinated and cleared with the Air Mission Commander.  He will assign routes, altitudes and communications necessary to insure control.

ITEM:   Communication support for tactical operations.

DISCUSSION;     The signal equipment utilized in support of tactical operations for the 25th Inf Div in RVN has been reduced.  The airmobile concept employed by division eliminated the use of signal equipment mounted in 2 ½ ton truck, and required a similar signal element for support.  The equipment affected by this concept is the Radio Terminal (AN/MRC -69), Manual Telephone Central (AN/MTC -3), and Telegraph Terminal (AN/MSC - 29).  The signal battalion has used the TO &E Manual Control Office (AN/MTC -7) and Teletypewriter Central Office set (AN/MGC - 17) which are mounted in ¾  ton trucks, to replace the AN/MTC -3 and AN/MSC - 29 respectively.  To replace the AN/MRC-69 with a piece of equi0pment that would be airmobile, an AN/MRC 34.5 (so designed by the Signal Battalion) was improvised.  This set consists of equipment from an AN/MRC-69 mounted in a ¾ ton trailer.  It provides 4 to 12 channels of VHF communications.  The accessory equipment to include:  TE-75 generators, is stored in a ¾ ton truck.  In addition, this equipment has a reduced height of 72 inches enabling it to be airlifted by the OH-47.

OBSERVATION:   The reduced signal element provides adequate communications for tactical operations.  The AN/MRC 34.5 has been on three operations:  EWA, KAJANA I & II.  Results were outstanding.

          (3)  (FOUO)  Organization and Training:                             
ITEM:     TO&E Changes

DISCUSSION:  The 125th Signal Battalion is preparing changes to the TO&E requesting additional equipment and personnel.  The following items will be requested.

(1)     Additional photographic equipment and personnel to augment the present photographic     service.

(2).     Special lightweight VHF Radio Terminals (AN/MRC-112's) to support the airmobile concept.

                 (3).     Additional machine-guns for the signal elements supporting tactical operations.

OBSERVATION:   Because of the geographical location and operational commitments, the additional equipment and personnel are necessary.

ITEM:   Pathfinder assistance is necessary in the conduct of airmobile operations.

DISCUSSION:   The 25th Aviation Battalion has learned through the conduct of airmobile operations over a four month period, that the assistance of pathfinder personnel is essential to the efficient accomplishment of airmobile assaults and extractions.  Operations conducted during the hours of darkness require pathfinder assistance both in the staging area and in the landing zone.  Night airmobile assaults cannot be effectively conducted without them.

OBSERVATION:   Due to the large number of airmobile operations being conducted by divisional units, recommend that a pathfinder detachment be provided each division size unit in RVN.

ITEM:   A division aviation battalion must have the capability to exercise adequate control over both organic and attached operational aircraft.

DISCUSSION:   A division aviation battalion must have a flight following capability.  This would enable the unit to recall aircraft for rapid reaction operations, provide flight and mission information, and to initiate search and rescue operations.  A flight control center, equipped with both FM and UHF radios, and manned by sufficient personnel for continuous 24 hour operations, is required to give the aviation battalion this capability.

OBSERVATION:   Current TO&E's do not provide this capability for division aviation battalions operating in RVN.  Recommend that personnel and equipment be authorized to implement a flight following center.


ITEM:   An Airfield Command Section is required to control and coordinate airfield activities at division level.

DISCUSSION:   The activity generated by organic and attached aircraft operating from a division base airfield is beyond the present control capability of the division aviation battalion.  The additional activity of refueling and rearming during the conduct of airmobile operations, together with traffic control for the numerous flights operating from the division base airfield, necessitates a control and coordinating agency for efficient functioning of airfield activities.

OBSERVATION:   In the absence of an Airfield Operating Detachment, it is recommended that an Airfield Command Section be authorized the aviation battalion to control airfield activities.

ITEM:   Additional helicopter maintenance personnel are required to maintain the desired availability rate of aircraft in RVN.

           DISCUSSION:   Increased aircraft maintenance requirements caused by operating in unfavorable     
climatic conditions, and by combat damage, severely increases the normal workload of assigned maintenance personnel.

OBSERVATION:   Recommend that sufficient additional helicopter maintenance personnel be authorized the aviation battalion in order to be able to implement a 24 hour maintenance operation.

ITEM:   Door gunners are essential for in-flight security of aircraft during both combat and administrative flights in RVN.

DISCUSSION;   During all flights of UH-1D helicopters, both the helicopter crew chief and a door gunner armed with M60 machine-guns provide in-flight security for the aircraft.  The need for armed door gunners is especially great when operating at low level.  Their worth has been proven during 5 years of helicopter operations in RVN.

OBSERVATION:   Current TO&E's do not provide for door gunners for each assigned UH-1 aircraft.  Recommend that they be authorized the aviation battalion to provide necessary in-flight security.

ITEM:   The aviation battalion has determined in conducting airmobile operations over a period of 4 months, that it is necessary to provide the Commanding General, each Brigade Commander, and the Aviation Battalion Commander with a UH-1D helicopter equipped with the Airborne Command Console AH/ASC-6.

DISCUSSION:   To provide the ground commander with adequate communication facilities with his subordinate units and supporting agencies, the airborne command control aircraft should be equipped with the Airborne Command Console AN/ASC-6.  The AN/ASC-6 also provides the Aviation Battalion Commander (Air Mission Commander) the communications capability with which to control airmobile operations.


OBSERVATION:        Recommend that sufficient aircraft equipped with the AN/ASC-6 console be provided the aviation battalion to fulfill operational needs.

ITEM:      Untrained aviation replacements are an unnecessary burden on a tactical organization.

DISCUSSION:   It is presently necessary to transition aviators by both type and model aircraft, and conduct aerial gunnery training for armed helicopter pilots.  This places a burden on aircraft availability, and reduces combat effectiveness.  It requires 25 hours of valuable UH-1 time to train in this model.  Training in gunnery and armed helicopter tactics is required by all aviators assigned to armed helicopters.  This requires a minimum of an additional 10 hours of aircraft time prior to combat.

OBSERVATION:  That individual aviator replacements be assigned according to their aircraft qualifications, or training be conducted prior to assignment to a tactical unit.

ITEM:   Generator Classes:

DISCUSSION:   Generators are the life-blood of a signal battalion.  Climatic conditions and their continued use require that all generator operators be familiar with the basic fundamentals of generators.  A generator class, examination, and critique has been conducted to determine what areas of instruction should be intensified.

OBSERVATION:   These classes have increased the operator's efficiency, and decreased generator down time.

          (4)   (C)   Intelligence.


ITEM:   Close liaison with RVN intelligence collection agencies.

DISCUSSION:  Close liaison with Sector and Sub-sector advisors, Special Forces detachments, and village chiefs has provided this headquarters with timely intelligence that would have been received too late for immediate reaction.

OBSERVATION:   Maintaining close liaison with the above mentioned agencies is necessary in order to maintain a timely and current intelligence system.

ITEM:   Red Haze missions.

DISCUSSION:   Red Haze missions are being flown over areas recently fired on by artillery.  Many reported emissions are, in fact, fires started by artillery fire.

OBSERVATION:   Coordination between Division G2 Air and Division Artillery operations will considerably reduce, if not eliminate, Red Haze missions over areas being subjected to artillery fire.
DISCUSSION:     Information collected by SLAP has been slow in reaching units which have an immediate reaction capability.  In many instances SLAR information gathered at night has not reached a firing unit until the following morning.

ITEM:   H & I Program:

DISCUSSION:   G2 Air conducted an extensive aerial reconnaissance over the area of operations during Operation FIREBALL  I.  As a consequence, much target information was gathered thereby permitting the artillery unit to immediately initiate an effective H & I program.  The success of this endeavor can be adjudged by the fact that an enemy mortar attack was not mounted on the artillery battery or supported unit even though both occupied VC dominated territory for three weeks.

OBSERVATION:   Development of a sound H & I plan prior to occupation of strange territory will considerably reduce the possibility of mortar attacks.

ITEM:   Intelligence furnished by RVN children.

DISCUSSION:  On 2 August 1966, several small children informed members of an armored cavalry platoon of the location of several mines which were located in a parking area adjacent to highway 1, southeast of CU CHI.  As a result of this information, three anti-tank mines were located and destroyed.

OBSERVATION:   Sincere efforts of US personnel to befriend the Vietnamese people often yield tangible results.

ITEM:   Quick reaction to perishable intelligence.

DISCUSSION:   The use of quick reaction forces that have reacted to perishable intelligence reports from agents and other collection agencies has been very successful.  If there is any delay in the reaction to this intelligence the target usually has disappeared.

OBSERVATION:   Quick reaction forces such as Eagle Flights are needed in order to react to timely intelligence.

ITEM:   The use of returnees (CHIEU HOI) as an important source of intelligence.


DISCUSSION:   Recent experience has proven that one of the most profitable sources of intelligence is a returnee (CHIEU HOI).  Many times the returnees have led US and ARVN troops to secret tunnels where weapons and supplies have been located.  The returnee also provides US/ARVN intelligence agencies with names of VC in the different villages.  Immediate operations to exploit this intelligence with the returnee accompanying the unit has proven most successful.

OBSERVATION:   One of the best sources of information concerning VC activities and supply routes has been the returnee (CHIEU HOI).

ITEM:   Interrogation teams at battalion level.

DISCUSSION:   The use of interrogation teams by battalions while operating as a separate mission has proven highly successful.  The information fathered by the team is immediately available tot the S2 and in some cases the captives have shown US forces the location of supplies and weapons.

OBSERVATION:   When battalions are on separate operations, interrogation teams at battalion level can provide the commander with timely intelligence.

ITEM:   Pictomaps.

DISCUSSION:   Only recently have pictomaps of our AO been made available to combat units.  Prior to that time, the standard 1:50,000 map and aerial photos were used for operations.  Now that pictomaps are available, the requirement for aerial photos has been greatly reduced.

OBSERVATION:   The use of pictomaps, scale 1:25,000 have proven extremely valuable to combat units.

ITEM:   Intelligence net.

DISCUSSION:   The use of a brigade intelligence net when two or more battalions are operating in the field provides the S2's with a means to transmit and receive intelligence details without congestion of the brigade command net.  In order to effectively operate an intelligence net, the requirement exists for each battalion to have a PRC-25 authorized for the S2.  With this capability there would be an improvement in the intelligence flow.

OBSERVATION:  Battalion S2's should be authorized  a PRC-25 and RTG since the jeep mounted radio is not available for heliborne operations.

ITEM:   Indigenous labor.

DISCUSSION:   Many of the same members of the labor force return to unite on a recurring basis.  Many guards, who are assigned to the duty frequently, become too friendly with the civilians.  The possibility of infiltration of the labor force by VC is an ever present threat.  Laxness or carelessness by the guards could have disastrous results.


OBSERVATION:   Guards must remain attentive and alert while in charge of the labor force.  They must be cautioned not to become too friendly with the civilians.

ITEM:   Aerial reconnaissance.

DISCUSSION:   Aerial reconnaissance of proposed LZ's is normally conducted in conjunction with airmobile assaults.  An aerial reconnaissance conducted jointly by the Airmobile Commander and the Troop Commander is highly desirable.  However, recent experience has shown that too many separate recons are being made by various elements.  The practice of over-reconning an objective area or LZ is highly detrimental to the airmobile assault, in that the enemy seems to be aware  of our intentions and is prepared to deliver heavy volumes of ground fire.  Continuous orbiting of the proposed LZ by numerous aircraft, is certain to compromise the tactical plan

OBSERVATION:   Reconnaissance must be held to a minimum when planning airmobile operations.  Devious flight routes and avoidance of the objective area must be employed to prevent direct enemy observation and possible compromise of the tactical plan.

ITEM:   Ground fire.

DISCUSSION:   The incidence of ground fire directed at aircraft within the TAOR ha increased in total numbers of rounds delivered and accuracy.  More automatic weapons are apparently being employed by the VC, especially in certain areas.  Hits are being sustained at higher altitudes which indicates the VC are developing more sophisticated techniques in leading the target.  Reports of heavy caliber automatic weapons are received in several INSUMS.  .50 caliber fire has been received by aircraft on two occasions in the TAOR.

OBSERVATION:  Aviators are instructed to vary flight path and altitude when repeatedly flying over known danger areas.  The use of low level (nap-of-the-earth) tactics is implemented when heavy caliber automatic weapons fire is encountered.

ITEM:   Ground Fire Charts.

DISCUSSION:   The ground fire chart is a valuable tool, by which routes, LZs, and dangerous areas can be pre-determined.  A 60 day presentation on the chart, sometimes races the path of an enemy force and provides valuable intelligence on enemy patterns of habit.  The chart is also used to brief new aviators, or those not familiar with the AO/

OBSERVATION:   Recommend that all units having organic aircraft maintain a ground fire chart.  Pilots must report all incidents of ground fire to their parent unit as soon as possible so that the chart can be constantly updated.


ITEM:    Interrogation,  Prisoners of War.  It is the policy of some VC units to have all their soldiers carry CHIEU HOI leaflets for use in the event of capture.                                                       
DISCUSSION:     Through interrogation of a VCC who belonged to the D14 Bn, Mobile Force, TAY NINH Province, it was learned that each soldier in that unit carries a CHIEU HOI leaflet.  He is instructed that in case of capture, he is to present the document and claim that he was on his way to rally.  The captive who furnished this information also used this tactic and only after several days of interrogation did he admit that he had no intention of rallying prior to his capture.

OBSERVATION:   A man who is captured automatically loses any rights he may have had under the CHIEU HOI Program.  He is a VCC and should be treated as a prisoner of war until proven otherwise.

ITEM:   The majority of the VCC who are captured, while not actually bearing arms, are almost always implicated by documents found on his person or those found near his place of capture.

DISCUSSION:   When a Vietnamese is apprehended in an operational area and he has no incriminating evidence on his person to prove he is a VC, the interrogation amounts to “his word against the interrogator's”.  Most persons whose names appear on VCC documents have difficulty explaining the circumstances.  To date, the following types of VC have been captured and confessed to being VC simply because the prompt evacuation of the person's documents or documents found in the immediate vicinity of the place of capture produced evidence which the VC could not deny.

            (1)     VC medic for DUC HUE District, HAU NGHIA Province.
(2)     Village finance cadre, DUC HUE District
(3)     A member of the DUC HOA District Military Provisions Section.
(4)     A member of G-20 Reconnaissance Company, SAIGON-GIA-DINH Special Region.

OBSERVATION:   It is imperative that documents captured on the person of a VC or near the place of capture accompany the VC during evacuation.

ITEM:     Approximately 1000 indigenous laborers are employed daily at the division base camp which presents an ideal vehicle to the VC for infiltration of espionage agents and saboteurs inside the division perimeter.  This local labor pool is constantly screened by the CI Section, 25th MI Det as part of Operation KLEEN, to detect any espionage or sabotage threat.                              (p41)
DISCUSSION:   The known and suspected VC elements, their families, and their sympathizers comprise a substantial segment of the civilian population in the area contiguous to the division base.  The following actions are currently in effect to minimize the risks inherent in such a labor force.

     (1)     A daily search and shakedown of all laborers prior to entering or leaving the base, with close supervision by noncommissioned US personnel to prevent the introduction or removal of contraband, espionage, or sabotage devices.  Women are hired in order to more effectively search women laborers.

     (2)     A continual screening of ID Cards, with periodic assistance by the National Police to detect bearers of false ID Cards in the division labor force.

     (3)     A continual collection and photocopying during the workday of laborer's ID cards provides a growing base of personnel data for comparison with current black and gray list holdings and for counterintelligence investigation.

                 (4)     Informants have been, and are being, developed at various levels within and without the base
                 camp to report on suspects within the labor force.

OBSERVATION:   Current search procedures reduce VC espionage potential to a minimum.  The ID Card checks hamper attempts to gain access with false documentation; developed informants and other counterintelligence measures have resulted in the detection and apprehension of six self confessed VC espionage agents, and the elimination of other known or suspected VC found in the division labor force.

ITEM:     Collection and recording of personnel data on known and suspected hostile personalities in positions to affect the mission of the division is one of the necessary functions of the Counterintelligence Section, 25th MI Detachment.  The growing compilations become a basic tool of division investigation and intelligence operations.

DISCUSSION:     At the onset of division operations in the current TAOR, local agencies furnished data on approximately 150 known or suspected VC.  At the close of the current quarter, division intelligence activities had increased the black and gray list holdings to nearly 1600 known or suspected VC personalities plus a listing of over 1500 employees and other individuals of intelligence interest.  These had initially been compiled in a conventional card file, but the requirements of the CHECKMATE program to include airmobile raids, dictated a greater flexibility in access to this centrally located card file.  The following actions were taken to meet operational needs:

     (1)     It was determined that Division AG Machine Records Branch could provide technical and automated assistance to reproduce old data and integrate new and additional data to the present black list and other intelligence personalities holdings.


     (2)     An alpha-numeric code was devised by personnel of the Counter-intelligence Section, 25th MI Det, to translate current files into a format usable by AG Machine Records Branch.

OBSERVATION:   The resultant machine records roster provide for a ready reproduction of current intelligence holdings in their entirety by geographic or populated area; by military unit or by types of personalities.  This form of automation permits simultaneous and instant use of the local division intelligence personalities assets by several elements of the division and in varied operational areas.  It also provides for ready dissemination of information to other headquarters.  The system has been accomplished with currently authorized personnel and equipment

ITEM:     Aerial photos of selected ambush sites have provided several advantages to ambush patrols.

DISCUSSION:  Then ambush patrols are furnished large scale aerial photos of ambush sites, the following advantages occur:

(1)     Thorough orientation of all patrol members regarding terrain features is possible prior to departure.
(2)     Best areas of concealment are revealed
(3)     Avenues of approach and escape are identified.
(4)     Any enemy defense within the kill zone such as trenches, AW positions, or possible bunkers can usually be identified by imagery interpreters over-printing these positions directly on the photograph.

OBSERVATION:   Units should exploit this asset to the fullest extent.  Personnel attending the 25th Inf Div Ambush Academy are presently schooled in this technique.

ITEM:   Tactical use of aerial photography in County Fair operations.

DISCUSSION:   Large scale aerial photographs of selected areas such as hamlets or villages, can be put together as a photo-mosaic to portray a specific area, with identifying data posted thereon, which can be successfully used as follows:

                (1)     When County Fair operations are planned, squad leaders are equipped with photos of the specific area with the exact houses or buildings marked that his squad is to search or exploit.  Complete coverage is assured beforehand.

     (2)     When used by interrogators, large scale aerial photos of a selected area enables a person being questioned to point out to the interrogator each individual house or position of interest being discussed.  This is an excellent aid to communication and understanding.               (p43)

OBSERVATION:   The above technique is being employed on a continuing basis by elements of the 25th Inf Div with considerable success.

ITEM:     Use of Special Imagery Interpretation Reports.

DISCUSSION:     Special imagery interpretation reports can be utilized to depict the enemy situation in a given area by portraying the information contained in the report directly on 1:25,000 picto-maps, thereby providing commanders with a graphic display of the terrain in an objective area.

OBSERVATION:   This technique should be applied during small unit actions utilizing the latest imagery interpretation reports that cover the objective area.  Special Imagery Interpretation Reports are distributed to battalion level on all aerial photo missions flown.

ITEM:     Targeting section at division level.

DISCUSSION:   The organization of the division level targeting section has proven extremely valuable in the collation and intelligence data.  This data is developed into a daily target list which provides FSR with a list of lucrative, active, target areas.  Additionally, for each planned operation, a supplemental target list is provided to the maneuver elements and supporting units.  Data collected includes but is not limited to the following:

(1)   Imagery interpretation reports.
(2)   SPAR reports
(3)   Red Haze land SLAR reports
(4)   Incidents of aircraft receiving fire.
(5)   Agents reports
(6)   All Order of Battle information.
(7)   Roadblocks, ambushes and attacks by the enemy.
(8)   Intelligence estimates and special studies.
(9)   Visual aerial reconnaissance reports.
(10) Long Range Reconnaissance Patrol reports.
(12) IPW reports

OBSERVATION:   The full utilization of this section has resulted in a continuous flow of lucrative targets to be exploited by TAC air, artillery, gunships and ground maneuver elements.  All units should continue to exploit this valuable resource.  In this connection, unit reports of defenses encountered and destroyed prove extremely valuable in keeping targeting data current and valid.

ITEM:     VC letter box numbers.

DISCUSSION:     Letter box numbers are one of the most positive means used to identify VC units.  It has been found that VC units may have several code/cover names, and the unit may switch cover names frequently to confuse friendly intelligence efforts.  Letter box numbers on the other hand are usually adhered to for an extended period of time.

OBSERVATION:   Units should catalogue VC letter box numbers for easy identification of units.

ITEM:     Leaflets utilized for possible informant recruitment.

DISCUSSION:     Several reward type leaflets have been published and distributed which instruct any person with information concerning the VC to write this information on the backside of the leaflet and mail it ot Box 12 at CU CHI, the District Headquarters.  The leaflet has one corner ticked which he is instructed to tear off and retain as a receipt.  The leaflet and the corner are both stamped with the same number.  He is instructed to report at a later date with his receipt to the District Office to ascertain if his information has been of intelligence value.

OBSERVATION:   This provides any Vietnamese with the anonymity he needs and desires while reporting information about VC activities, and offers an opportunity to recruit informants, either permanently or temporarily, through this screening system.

ITEM:     CHLIEU HOI Enticement.

DISCUSSION;     Psywar leaflets to date concerning CHIEU HOIs consist mainly of written enticements which the average VC cannot read, or cartoons which he does not accept.  The interrogation of CHIEU HOIs show a high illiteracy rate, and indicates that several of the major reasons for rallying consist of the following:

(1)   Constant hardships such as living in trenches and constantly on the move.
(2)   Constant fear of artillery fire and air strikes.
(3)   Constant hard work and lack of compensation.
(4)   Loneliness, separation from their families                         (p45)
(5)   Lack of, or scarcity of food.
(6)   False promises by the VC cadres regarding compensations and rewards.  Utilizing these reasons, an approach is being made to have photographs of actual scenes of CHIEU HOIs and even ARVN families in a comfortable  home with ample food and clothing, happy children, and a close knot happy family depicted in leaflet form.  Each photograph would include a caption in simple Vietnamese which they can understand.

OBSERVATION:   Leaflets of this type would have a greater psychological impact on the average VC as he will be able to observe the photos and more importantly, understand them, thereby increasing the possibilities of his rallying.

ITEM:     Handling National Policemen during field operations.

DISCUSSION:     Field operations conducted by division units will invariable require National Policemen (NP).  The proper utilization of these NPs will materially affect the degree of success a unit attains during field operations.  The treatment they receive and the method by which they are used while attached to a unit will also be of major importance in maintaining the close relationship needed with the National Police authorities to carry on this joint effort.  The following techniques should be followed when working with NPs.

(1)      Keep a NP, with interpreter, near the commander at all times to enable the commander to properly transmit his instructions to the NPs.
(2)       Keep NPs escorted at all times with US troops.  The NPs have a tendency to wander and the unit may lose control of their activities.
(3)       Maintain a roster of attached NPs with their respective Police Stations indicated.  This will assist in returning them to their proper duty station after the operation.
(4)       Muster NPs each morning and night for control and accountability.
(5)       When the NPs are interrogating, keep everyone away.
(6)       Rice is their staple food.  Conditions permiting, feed them rice with a C-Ration.
(7)       Give appropriate commendations to those NPs whom you believe have performed beyond their normal duties.

OBSERVATION:   Every little effort made to assist these NPs will reflect directly or indirectly on the success of the operations, and enhance our relationship with the NP authorities for their constant support which we must have.

                      (5)     (FOUO)   Logistics.                                  

ITEM:      Logistical support for operations.

DISCUSSION;   Normally, brigades operating more than 20 minutes in flight time from base camp should be supplemented by sufficient personnel from Support Command to operate a Forward Support Operations Center (FSOC).   The FSOC should have the capability to receive, store and issue all classes of supplies for brigade operations.  Maintenance and medical support should also be adequate for sustained field operations.  The FSOC should be resupplied in bulk by base camp RSOC.  Forward units are in turn resupplied from FSOC by air/ground as appropriate.

OBSERVATION:   The resupply by aircraft from base camp is undesirable due to time consumed and refueling.

ITEM:     The requirement for float helicopters.

DISCUSSION:     Whenever there is extensive battle damage incurred by any of the units' helicopters, the divisions combat effectiveness is automatically reduced.  Provisions should be made to replace these aircraft by float aircraft to maintain a high availability.  The accepted availability criteria has been set at 80% within this theater.  However, experience has shown that the armed helicopters fall below this level primarily because of battle damage.  The present availability rate for armed helicopers runs at less the 60%.  If a float were to be established to replace aircraft which require maintenance for a period in excess of one week, the effectiveness of the unit would be considerably increased.

OBSERVATION:   That a maintenance float for armed helicopters be established and maintained at the division direct support unit for issue to the using unit whenever an aircraft is required to be grounded for an extensive period.  It is felt that an acceptable increase in availability would be realized if the float criteria were established at 20% of the division aircraft authorization.

ITEM:     High attrition of selected items due to environment

DISCUSISON:     Weather, terrain and the requirements of operations in this area cause a high usage factor of certain items of supply.  Item such as steel tow cables, tow pintles, tow pins, light tow bars and heavy tow bars are used extensively due to the soft areas in which heavy tacked vehicles must operate.  These items are constantly breaking or in need of replacement.  Suspension parts for track M113, and M88's are also in short supply because of continued heavy usage and mine damage.

OBSERVATION:   That the high attrition rate of selected items be considered in order to keep the supply system responsive to user's demands at theater Army level.


ITEM:     Helicopter loading and unloading crews.

DISCUSSION;     When receiving and extracting equipment and supplies from forward areas by helicopters, sufficient personnel, organized as a team, should be immediately available to load and off-load aircraft with minimum loss of time.  Teams should clear the helicopter pad quickly so as not to interfere with incoming ships.

OBSERVATION:   Teams should be organized to load and off-load helicopters with minimum loss of time.

ITEM:     Control of helicopters.

DISCUSSION;     When more than one unit of a brigade is being resupplied by air, all helicopters should be controlled by the Brigade S4.

OBSERVATION:   Coordination is required to appropriately redistribute helicopters in favor of the most demanding unit.  A representative from the Brigade S4 stationed on the resupply pad is of great importance for maintaining control.

ITEM:     Communication power units.

DISCUSSION;      Adequate power units should be made available to units before deployment.  This unit is critically short of adequate power units.  72 each, 5KW generators are being used with communications equipment that requires 10KW generators.  Most of these generators have surpassed their life expectancy by 50 per cent.  As expected, down-time is increasing rapidly.  These unreliable generators are a serious threat to division communications.

OBSERVATION:    Adequate power units should be made available to units before deployment.

ITEM:     Artillery propelling charges.

DISCUSSION;   Damp powder seriously affects the accuracy of artillery projectiles.  Every effort should be made to keep powder dry.  Canisters for 155/8 inch propelling charges must be securely sealed.  Semi-fixed ammunition, once exposed to weather, will accumulate moisture rapidly and should be broken open only in small quantities.  If repacked in fiber containers, the containers must be resealed.  A system of ammunition rotation which provides for firing of opened rounds and firing of repacked rounds before breaking open additional ammunition will considerably reduce damp powder problems.

OBSERVATION:   Storage of propelling charges and rotation of ammunition must be carefully planned and actively supervised, especially during the Vietnam monsoon season.


ITEM:     Rotation of rations.

DISCUSSION:     Rations are susceptible to deterioration due to climatic conditions and storage facilities.

OBSERVATIONS:   Losses can be prevented by off ground storage and continual rotation.  A cover should be provided which shields the rations from sun and rain without preventing adequate air circulation.

                 (6)     Other.

                                     a.   (FOUO)     Civic Action.

ITEM:     Immediate response to death, injury or property damage caused by US units during operations.

DISCUSSION:     As soon as possible after learning that death, injury or property damage has been caused, an informal investigation is conducted in order to determine what immediate relief can be affected.  MILCAP forms are distributed.

OBSERVATION:   Monetary and material assistance should be channeled through local officials.  The showing of interest in the people's problems by the GVN is a major step in strengthening the people's faith in their government.

ITEM:     Effectiveness of Helping Hand, US  Aid, and Catholic Relief Society commodities.

DISCUSSSION:     Commodities from these organizations are used to support plans and objectives in conjunction with military operations and to initiate or support self-help projects.

OBSERVATION:   The amount and type of aid should be determined by local officials.  The commodities should also be distributed by local officials.  Care should be exercised to insure that these commodities are not distributed to the extent of disrupting the local economy.  The distribution has been effective when done properly.  This has been evident by the changed attitude of the people towards the local officials and the US personnel.

ITEM:   Effectiveness of English classes.

DISCUSSSION:   Classes are being conducted with the local officials, businessmen, school teachers, nurses, and young children desiring to learn the English language.

OBSERVATION:   The English classes seem to be achieving the main objective, i.e., teaching English to the Vietnamese, giving the Vietnamese people a better idea of the American way of life and why the American soldiers are in Vietnam.  It also increases understanding between the Vietnamese people and the US soldier.  The most effective classes do not have more than 10 people.  It is better to adequately teach a few people than to have a large class learn relatively nothing.


ITEM:   MEDCAP must be handled properly to insure maximum results.

DISCUSSION:   There are several factors which a MEDCAP must include to be successful.  Adequate security, working area with some degree of privacy, and one interpreter per each doctor as a minimum is required.  Local health officials should establish a screening program so that the doctor's time is effectively used.  Crowd control will require extra personnel.  A portable shower unit can effectively be used to clean patients and draw any inquisitive children to another area.  Any civic action distribution should be held in an area away the MEDCAP site.

OBSERVATION:   All incoming S5s and surgeons should be briefed on proper steps for a successful MEDCAP.
                  b.     Psychological Operations.                        


ITEM:     Use of aircraft in psychological operations.

DISCUSSSION:     Both the OH-23 and UH-1 helicopters have been successfully employed in support of psychological operations.  Aircraft have been flown for leaflet drops and loudspeaker missions.  The OH-23 has proven to be a more desirable vehicle for leaflet drops than the UH-1.  The wind flow path around a UH-1 aircraft tends to pull the leaflets back in the open door and scatter them inside the helicopter.

OBSERVATION:   The OH-23 is well suited for employment in support of PSYOPS when available.  The following flight techniques are deemed advisable in the conduct of these missions:

Maintain an altitude of at least 1500 feet above the terrain.
Make trial leaflet drops to note wind direction and velocity.
Note speaker amplification and maintain an altitude of 2000 feet on speaker missions.
Do not hover over the drop area as helicopters are lucrative targets for the VC.

ITEM:     Effect of psychological operations.

DISCUSSSION:     Leaflets and loudspeakers used in various areas have a positive effect on the village people.

OBSERVATION:   Local officials will furnish sound ideas for effective propaganda in their areas.  They wish to counter the VC influence and are anxious for psy-war operations to be conducted.  Due to lack of communication media (Radio, TV, Press) pamphlets and loudspeakers are an effective means to tell the people what is happening


     b.   (C)   Commander's Recommendations:                                  
Unlike previous operations in the TAOR in which the objective was the location and destruction
Of VC main and local force units, supplies, fortifications and base areas, three operations, Operations FORT SMITH east of TRANG BANG (XT4519), Operations FRESNO west of BAO TRAI (XT5204), and Operation SANTE FE east of BAO TRAI, were primarily intended as grass roots pacification ventures.  These operations positioned an Inf Bn (+) in an insecure area and by a combination of joint civil affairs and limited combat operations, improved the security situation and made the Vietnamese government's presence and position understood by the local populace.  The pilot pacification operation was MAILI conducted by the 1/27th Inf in the DUC LAP area during 27 April - 12 May.  The experiences and lessons learned from this operation were applied to the three other operations.  Obviously an operation of this nature, geared to winning over the local populace and undermining VC influence in a particular area, will not result in spectacular results or large VC losses.  The effects are nonetheless impressive and in the long run perhaps even more critical to victory in Vietnam.  Results that have been ascertained thus far include:

                 (a)     Introduction of GVN officials into villages and hamlets which because of the existing security situation, has not been ventured into for several years.
     (b)     Marked increase in the commercial traffic along the main LOC's and tertiary trails in the
operational area.  Particularly noteworthy is the current volume of traffic on the road between CU CHI and the province capitol BAO TRAI.  Although previously considered under government control, this road was seldom traveled by government or military vehicles without escort.

     (c)     Amelioration of the US and Vietnamese government's image through the conduct of
“Country Fair”, MEDCAP, distribution of Helping Hand goods, and other civil affairs projects in the operational area.

     (d)     The breaching of the VC local political and military organization and long standing
infrastructure in the area.  This is evidenced by the noticeable increase in voluntary informants, and the willingness of the VCC and VCS apprehended to implicate fellow cell committee members.  In one case, a VC platoon leader through his wife indicated his desire to surrender to US forces in the area.  Once apprehended, the platoon leader turned in his weapon and led a patrol to the hiding places of 9 other members of his platoon who were captured on the spot.  On four separate occasion s village children also led patrols to VC arms caches containing numerous mortar rounds, grenades and booby taps.

     (e)     Improvement of the cooperation and rapport between the 25th Infantry Division and
Vietnamese Government and Military Authorities in HAU NGHIA Province, which in turn has resulted in a significant increase in military operations against the VC by the 25th Division.


                 (f)     A bolstering of the spirit and substance of the RF and PF effectiveness in the operational area as a result of :  (1) reaction forces, (2)  fire support, to include gunships and illumination, and (3)  physical improvement of outpost fortifications   (For a more detailed analysis see App 14,  25th Div Pacification Operations in HAU NGHIA Province (U).)  

          (2)     The use of attached personnel carriers on S&D operations as well as pacification operations has greatly enhanced the ability of a dismounted infantry battalion to rapidly close with and destroy the enemy.  When an infantry battalion has attached personnel carriers, its movement is not as vulnerable to a few well positioned, well camouflaged enemy riflemen.  Valuable time is often lost determining the location of a sniper.  When track vehicles are a part of the maneuver element of an infantry battalion, this time is greatly reduced because the tracked maneuver element can close rapidly with the enemy to reduce or eliminate the sniper fire.

          (3)     During Operations FIREBALL  I and COCO PALMS, single firing batteries, with security attachments, were deployed in a direct support role for battalion size maneuver elements.  In each case, a command and control group was utilized.  The group consisted of a field grade officer, a lieutenant, NCO representatives of the Battalion S2 and S3 sections, one clerk and two RTO's.  The command group provided tactical fire control, the necessary command structure, insured that all personnel were briefed on the operation in progress and aware of the friendly and enemy situation, and aided in the coordination of supporting/reinforcing fires.

          (4)       Use of 155mm fires in direct support of infantry advancing in heavy undergrowth of semi-forested areas has proved effective.

          (5)     Adverse weather and bad road conditions during the monsoon season require units to  load vehicles only to prescribed load limits

           (6)     When operating during the monsoon season, tracked vehicles are essential to insure emplacement and extraction of artillery pieces and vehicles.

           (7)     The capability of the aviation battalion to respond rapidly and effectively to a wide variety of combat aviation missions has resulted primarily from the development of combat experienced small unit leaders and flight crews.  Perpetuation of this capability will be dependent upon the timely input of replacements for those personnel.
          (8)   Experience has proven that an infantry division operating in a counter insurgency environment requires a minimum of two organic airmobile companies.  Airmobile companies in a direct support role are not responsive to the division.  Planning is hampered by daily changing of direct support companies, and non-availability of support frequently requires radical changes in the ground tactical plan.  An MTOE adding an additional airmobile company to the division has been submitted.

 Eye Witness Account 11 May 68-LRRP 3/4 Cav


     On 11 May 1968, an eighteen man killer team from 3rd Squadron, 4th Cavalry LRRP element was inserted by eagle flight 1500 meters from the Saigon River in the Hobo Woods. The team moved several hundred meters and was pinned down by intense fire from a large NVA force. We were receiving small arms, automatic weapons, and RPG fire. We took up a position in a large bomb crater and started to return the fire. It wasn't long before we realized the NVA force had our team surrounded. We then called for air support and a fire team from Company B, 25th Aviation Battalion came tour assistance. Diamondhead 10 coordinated with us and then told us to keep our heads down he was coming in close; this was necessary since the enemy was about 25 meters in front of us. The gunships worked their way around our position and killed about 6 Viet Cong on their first pass. Even though the gunships were receiving enemy ground fire they continued to pound the enemy around us with deadly and accurate fire. When the enemy fire ceased Diamondhead 10 told us to move to a clearing 100 meters away and to wait for the slicks to arrive. As we moved to the clearing the gunships dangerously exposed themselves as they flew over us at very low-level to make sure the Viet Cong didn't have an ambush set up for us. When we got to the pickup zone we secured the area and waited for the slicks. When the slicks arrived they started to receive heavy enemy fire. Even though it was dark the slicks covered by another fire team Diamondhead 30, without regard to their own safety came into the small landing zone. One of the slicks was heavily damaged but returned to Cu Chi safely. The bravery of every crewmember that day was directly responsible for many valuable lives being saved. The courage and skill displayed by all crewmembers is praiseworthy and deserving of any award bestowed upon them.

 Eye Witness Account 11 May 68-Diamondhead 10


     On 11 May 1968 at about 1830 the Diamondhead 10 light fire team was scrambled to coordinates XT647225 to provide close air support to the Cobra 23 element. Upon arrival in the area Diamondhead 10 contacted Cobra 23. Cobra 23 was located inside a large bomb crater with the rest of his element. He was surrounded by Viet Cong, and numerous attempts were made to overrun his position. The Diamondhead 10 light fire team was asked to concentrate on the area to his west about 25 meters out. The fire team expended half its ordinance on that area and neutralized the target area even though  the fire team was receiving intense enemy fire during each firing pass from several locations. An attempt was made by the Viet cong to overrun the Cobra 23 element from the North but Diamondhead 10 immediately rolled in an ended the Viet cong effort by killing 6 Viet cong and wounding others. The East flank of Cobra 23 was threatened but the area was neutralized by Diamondhead 10. After forty five minutes of capping the area and killing many Viet Cong, cobra 23 was satisfied that he could move into a landing zone to the south for extraction. His element had reconned the area by fire and the Diamondhead 10 fire team made continuous low level passes ahead of the Cobra element to insure that no ambush had been prepared. The Cobra 23 element made it into the landing zone safely and were lined up for pickup. The Diamondhead 10 fire team helped coordinate with Clipper to arrange a team of slicks for pickup. Diamondhead 30 came on station and was briefed by the Diamondhead 10 team. When the briefing was complete the Diamondhead 10 team was forced to return to Cu Chi to rearm and refuel. They were then diverted to another mission.
