          e.     Intelligence.

               (1)     VC Activity

                    (a)     February 1967

                         1     General:  VC activity remained at a high level of intensity due to Operation GADSDEN and JUNCTION CITY in War Zone C.  This activity is attributed to the presence of elements of the 271st Regiment and 70th Regiment as well as elements of COSVN within the operational area.  There has been an increase in enemy activity around the Division Base Camp area which is attributable to the absence of most of the Division on operations in War Zone C.  Incidents of anti-aircraft fire by VC units decreased from 96 in January to 62 in February.

                         2     Significant Operations:

                              a     On 8 February, Recon Plt, 4th Bn (M), 23rd Inf received SA and rifle grenade fire from the CAMBODIAN side of the river vic WT967715.  Fire was returned.

                              b     On 26 February, A Co, 4th Bn, 9th Inf, with elements of Co A, 6th Engrs attached, received heavy SA, AW, rifle grenade and mortar fire from an estimated 250 VC, at XT701191.  Fire was returned with SA, AW, mortars and Arty.  Area was illuminated by use of flare ships and the engagement was supported by airstrikes.  A reactionary force consisting of Co B, 4th Bn, 9th Inf elements and Trp A, 3rd Sqdn, 4th Cav elements encountered an ambush en route to Co A, 4th Bn, 9th Inf's location, but penetrated it successfully.  As a result of the complete action which began at 260030 February and terminated at approximately 260600 February, VC casualties were 113 KIA (BC) and 33 KIA (poss).  Captured were 2 US BARs, 1 AK-47 rifle, 1 CHICOM carbine with grenade launcher, 1 Russian light machine gun, 2 RPG-2 rocket launchers with 18 RPG-2 rds, 1 M1 rifle and 1 .50 Cal tripod.  A PW, HUYNH VAN HUYNH, captured in the area was identified as an Assistant Squad Leader, 2nd Plt, 5th Company, 1st Battalion, MR IV.  Numerous documents captured on the battlefield made reference to the MR IV Bn, indicating that 1st Bn, MR IV was the unit that initiated the action.

                         3     The VC continue to be forced from their base and supply areas by friendly operations.  The loss of major caches will continue to affect the tactical operations of the VC in the future.

                         4     The presence of US Forces in the Division area of operations continues to give the people confidence in their government and government's ability to protect them from the VC.

                    (b)     March 1967

                         1     General:  VC activity remained at a high level of intensity during the month of March.  A significant increase in mortar attacks against U.S. unit command posts and base camps was noted.  Approximately 700 mortar rounds of various types were received by Division elements during the period, including the employment of 120mm mortars against the 196th (Lt) (Sep) Inf Bde at BAU CO (XT2868).  Most of the enemy contact which occurred during Operation JUNCTION CITY, WIALUA and MAKALAPA was with small enemy elements from 3 to 6 men, left behind to harass US forces.  However, during Operation JUNCTION CITY, VC forces engaged US forces in platoon strength and higher when necessary to protect critical installations or when they had an apparent advantage which could be decisively exploited and used for propaganda purposes.  The latter is believed to be the case in the VC Regimental attack of Fire Support Base GOLD which is narrated in detail in paragraph 1a (9) above.  The attack coincided with President Johnson's arrival at GUAM and showed the VC forces' willingness to accept heavy casualties in an attempt to achieve a military and political victory.

                         2     Significant Operations:

                              a     On 1 March, C Co, 2nd Bn, 34th Armor received heavy SA, AW, Mortar and RR fire from an estimated VC Battalion at XT414441.  Enemy losses:  13 VC KIA (BC), 35 VC KIA (poss) (no unit identification), 4 AK-47 assault rifles, 3 RPG-2 launchers, 2 CHICOM carbines and 80 grenades were captured.

                              c     On 15 March at 2000 hours, the 25th Infantry Division Base Camp at CU CHI received 50 rounds of 82mm mortar fire and 25 rounds of 75mm RR fire.  Fire was returned with artillery.  Enemy losses:  Unknown.

                              d     On 21 March at 0640 hours, patrols from 3/22 Inf made contact with a VC force at SUOI TRE (XT385715).  This contact triggered an attack against the 3/22 Inf and the 2/77 Arty by the 272nd Regt, supported by fire from 60mm and 82mm mortars, recoilless rifle and RPG-2 rocket launchers.  The 2/12 Inf, 2/22 Inf (M) and 2/34 Armor (-) reinforced the units under attack.  Contact lasted until 1100 hours and airstrikes and artillery pounded the area throughout the afternoon.  Enemy losses:  647 VC KIA (BC), 6 VC PWs, 93 small arms ammunition, 579 RPG-2 rounds, 1900 stick grenades, and 20 recoilless rifle rounds.  See Para 1a (9).

                    (c)     April 1967

                         1     General:  VC activity remained at a high level of intensity during the month.  There were 130 reports of enemy contact, 57 reports of antiaircraft fire, 58 antitank mining incidents and 46 antipersonnel mining incidents.  Eleven obstacles were cleared along the main supply route during the period.  The majority of the enemy contact was with small size VC elements of ten men or less.  A significant number of VC weapons were captured by US Forces.

                         2     Significant Operations:

                              a     Operation JUNCTION CITY continued in War Zone “C” with the 1st Bde, 9th Div continuing Phase III of the operation on 20 April 1967.  The only significant enemy contact occurred on 27 April 1967.  Co B, 2nd Bn, 47th Inf (Mech), received small arms and automatic weapons fire from 2 VC squads.  Fire was returned with small arms, automatic weapons and artillery.  Results:  4 VC KIA (BC).  Documents found on the bodies identified the 1st Bn, 70th Guard Regt.

                              b     Operation MAKALAPA continued in the “Pineapple Area” until 21 April 1967.  The only significant enemy contact occurred on 16 April 1967.  First Bn, 27th Inf, on an EAGLE FLIGHT operation vic XS567915, engaged an estimated VC company with small arms and automatic weapons.  Artillery, gunships and airstrikes supported the engagement.  Results:  22 VC KIA (BC), 72 VC KIA (poss) and 2 VC PW.  The PW's were from (a) HUUTHLANH Village Guerrilla Force and (b) GINH TAU Security Squad, BINH TAN District.  On 15 and 16 April 1967, Co A, 2nd Bn, 14th Inf, located weapons caches at XS7631865 and XS633868.  A total of 74 weapons were captured and included one 8mm mortar, two 60mm mortars, two 75mm recoilless rifles, two 57mm recoilless rifles and three light machine guns.

                              c     Operation MANHATTAN began on 23 April 1967, in the vic of the BOI LOI Woods.  A large number of mines and booby traps were encountered during the initial phase of the operation.  Enemy contacts consisted mainly of harassing attacks by small groups of from 3 to 6 VC.  On 27 April 1967, Co A, 2nd Bn, 14th Inf located a weapons cache at XT503347 consisting of 105 small arms weapons and 12 crew served weapons.  In addition, over 100,000 rds of SA ammunition were destroyed.

                              d     The 3rd Sqdn, 4th Cav, conducted local Search and Destroy Operations in the vic of TRANG BANG and in the FILHOL Plantation.  The most significant enemy contact occurred on 20 April 1967, during SABER THRUST.  Co A and D Trp, 3rd Sqdn, 4th Cav engaged an estimated VC Platoon at XT371370.  Results:  12 VC KIA (BC), 8 VC KIA (poss).  Documents found on one VC body identified the 401 Company, D-14 Bn.

                         3     US operations conducted during the month continued to force the VC from their base areas.  Enemy losses in manpower, facilities and equipment are expected to reduce the effectiveness of VC units in War Zone “C”, the BOI LOI - HO BO Woods Complex and the Pineapple area.  

                         4     The US/ ARVN Joint Operations Centers continue to operate efficiently, adding greatly to the overall intelligence effort of US/ARVN Forces.

               (2)     Long Range Reconnaissance Patrol (LRRP)

                    (a)     Operations.  During the reporting period, 1 Feb 67 thru 30 Apr 67, the division LRRP conducted missions for the ACofS, G2, the Division and the 3/4 Cav.  There were a total of 29 patrols conducted in HAU NGHIA, BINH DUONG and TAY NIN Provinces.  The LRRP has the capability of operating at extended distances and for extended periods from the division base.  The patrols gain information concerning enemy movement patterns, unit locations and installation locations.  The LRRP has been utilized as an economy of force measure to screen the flanks of division units conducting operations.

                    (b)     Training.     There were two internal 3-week training programs conducted by LRRP.  Twenty-seven members completed the course.  Twenty-one members of the Division LRRP have attended the 5th SPG MACV RECONDO School.

               (3)     Counterintelligence.  The Counterintelligence Section continued liaison to and with all echelons of local government and with counterintelligence counterparts of the Army of the Republic of Vietnam with which the 25th Infantry Division came in contact.  Essential operations such as personnel security investigations, security inspections and security checks were continued.  Files containing the infrastructure of the Viet Cong and files of “Black List”, “White List”, and “Grey List” personalities were expanded and revised.  Counterintelligence operations have resulted in the capture of 27 Viet Cong from within the division's indigenous work force since July 1966.  Of that number, 6 persons have been apprehended and neutralized during the period of 1 February 1967 to 30 April 1967.

                    (b)     During April 1967, project OREGON required 351 G-130 sorties.  The Division Transportation Office was on site at the departure airfield to provide technical advice and staff coordination.

                    (c)     The large amount of personnel departing the division on PCS movement was reflected in the activity of the Baggage Section the past (3) months.  During the quarter, the baggage section moved 3,090 pieces of baggage weighing 229,828 pounds for 2,053 personnel.

                    (c)     Average for quarter (tons/day)          63.0

          g.     Administration

               (1)     Personnel.  During the past quarter, the personnel posture of the division has been excellent.  Assigned strength (approximately 106%) exceeded the authorized strength.  This average has been maintained in an attempt to keep the division PDY above 100%.  There continues to be a shortage of Infantry and Artillery NCO's grades E5 and E6.  Other MOS that this headquarters places in the critically short category are:  11D40; 11F20; 11F40; 26C20; 63E20; 82C10 and 91B20.  These shortages have occurred as a result of lack of fill action against requisitions.  Also, there are some instances where personnel in lower grades have been used to fill requisition of NCO's.  The overall officer strength of the division has decreased considerably during this reporting period.  Although assigned strength remains at 102%, the present for duty strength has dropped to 97%.  This deficit is primarily due to diversions and the non-fill of valid requisitions, which accounts for a shortfall of 43 officers, but also includes 21 combat losses which have not been replaced.

          h.     Revolutionary Development Support

               (1)     Significant Organization or Unit Activities.

                    (a)     Regular liaison visits were made to MACV and (illegible) in the provinces of NAU NGHIA, BINH DUONG, TAY NINH, GIA DINH and LONG AN.  During the quarter, liaison was also made with IIFFORCEV.

                    (b)     Two studies were written o the Combined Lightning Concept.  These studies were designed to answer questions on command, commo, and support of the Combined Lightning concept.  An information letter on the Combined Lightning concept was prepared for transmission to General CHINH, 29th ARVN commanding General to initiate staff planning by the 25th ARVN.  In April, the CLC was transposed to draft form and final plans are now being completed.

                    (c)     The departure of LTC Bashore (SARDS) caused a reorganization of the Division Revolutionary Development Staff Section.  The Revolutionary Development Brand and its associated activities was placed under control of the ACofS G5.

                    (d)     The Revolutionary Development Branch has adopted the New MACV Hamlet Evaluation Rating System to report status of hamlets in the 25th Inf Div's TAOR.

                    (e)     The Revolutionary Development Branch provided Statistics and initial coordination for the ACofS, G3 to consider the possible use of US 25th Div resources to help provide security for the GVN village and hamlet elections in April.

                    (f)     On 30 April, the Commanding General of the 25th Inf Div escorted Brigadier General W. A. Knowlton, Director of Revolutionary Development Support, accompanied by the G5 on a tour of the RD Team working in XOM HUE hamlet in CU CHI District.  Prior to entering the hamlet, BG Knowlton was briefed on current and future RD projects and the status of the RD Teams in the 25th Inf Div's TAOR.

               (2)     Hamlet evaluation rating changes from initial report in Feb - Mar:

                    (a)     HAU NGHIA Province:

                         1     DUC HOA District - TAN AN HOA Village - MUY LON (XT615110) changed from D to C rating.

                         2     CU CHI District - TAN AN HOA Village - AN LOI Hamlet (XT455210) changed from D to C Rating.

                         3     TRANG BANG District - AN HOA Village - AN LOI Hamlet (XT455210) changed from D to C rating.

                    (b)     BINH DUONG Province:

                         1     LAI THIEU District - AN SON Village - AN PHU Hamlet (XT825080) changed from D to C rating.

                         2     LAI THIEU District - AN SON Village - AN HOA Hamlet (XT830095) changed from D to C rating.

                         3     BEN CAT District - AN DIEN Village - KIEN DIEN Hmlet (XT732323) changed from D to VC rating.

               (3)     Revolutionary Development operational factors or activities contributing to lessons learned.

                    (a)     Observations:

                         1     The new MACV Hamlet Evaluation Rating System was first initiated during the month of February with the first results available in late March.  The new system rates the hamlets from A to E or VC.  The new report is completed by the MACV District Advisor and shows a more realistic evaluation of hamlet status than the old GVN system.  Some problems have been discovered due to the subjectivity of the report.  However, detailed guidance is available on the filling out of the report.

                         2     Each hamlet is evaluated on eighteen different points - nine involving security and nine community development points.  After computation, the final ratings are furnished this office.  If the ratings of these eighteen separate points could be provided, the information contained therein would give a clearer picture of the hamlet, i.e., that a hamlet with low overall hamlet rating was due to a lack if community development points versus security points.  This information would be very useful at this level.

                         3     Due to the deletion of GIA DINH and LONG AN Provinces from the Division's TAOR, the RD and hamlet evaluation data is no longer kept by this office.

                         4     The Combined Lightning Concept was studied and a workable solution was proposed.  Basically, the concept is one US squad, one ARVN squad, and one PF squad together in one outpost.  Proposals for training and operational control have been finalized and now are awaiting final decision by ARVN and US commanders.

                         5     Village elections were held through the month of April and will continue through the next quarter.  Elections were held in the secured villages only.  The following number of village elections took place during the month of April.  TAY NINH Province, 23; HAU NGHIA Province, 6; PHU HOA 7& TRI TAM Districts of BINH DUONG Province, 5.  US units assisted the 25th ARVN Division when asked to provide additional security.  The election turnout during April appeared to be favorable; reports will be available at the conclusion of the elections.

                         6     Liaison is being established at district level by the RD Officer and NCO with attention given to districts where RD teams are currently active.  It was found that more specific information is available in reference to RD Teams and RD activities at this level.  Emphasis will be placed in the future in visiting district advisors.

                         7     The last two months of the quarter have shown an upturn in RD Team effort; however, it appears that some of the teams will not accomplish all of their goals for 1967.  The overriding cause for this seems to be weak team leadership.

          i.     Civic Action

               (1)     Significant Organization or Unit Activities.

                    (a)     During the reporting period, the Division lost Operational control of the 196th Light Infantry Brigade.  The 8th AA Platoon of the (illegible) CA Company was attached to the 3rd Bde, 4th Division at DAU TIENG but remained in their present position at TAY NINH.  The team assists the 1st Bde, 9th Division now located at TAY NINH.

                    (b)     Statistical Summary:

                                             FEB - APR     TO DATE
                         Helping Hand Recipients     20,165     89,867
                         MEDCAP Patients     25,999     98,977
                         Health & Sanitation Projects     15     1,199
                         Construction          52     440
                         Education and Training     6     170
                         Community Relations     88     817

                    (c)     MEDCAPS during this quarter showed a slight decline from 317 to 237 conducted.  The number of patients treated also showed a slight decline from 34,500 to 31,671.  Additional projects of training GVN medical personnel and conducting maternity clinic continued with approximately 50 people receiving some training.

                    (d)     The helping Hand program provided commodities to needy individuals.  Tents were provided to refugees at DAU TIENG in addition to clothing and other necessities required, such as carpenter kits, family kits and a midwife kit.  Approximately 275 evacuees from the MANHATTAN Operational Area were affected.  The following is a summary of Helping Hand issues during the quarter:

                    ITEM               QUANTITY
                    Books               1 “C” Box and 60 in English
                    Candy               80 Ind

                    Wheat               10 Bags

                    (e)     Construction:  The division actively participated in 52 construction projects from repair of roads and bridges to school repair and painting.  Emphasis was placed on schools and playgrounds.  Construction projects during the quarter included:

     1     Roads repaired:  7 (approx 35 km)     6     Latrines:  4
     2     Bridges constructed:  1          7     Walls built:  3
     3     Fences:  3                         8     Dispensaries:  3
     4     Playgrounds:  1                    9     Miscellaneous:  18
     5     Classrooms repaired:  9

                    (f)     RF/PF Assistance:  Assistance to RF/PF Forces continued during the quarter with two outposts being constructed, one at PHUOC VINH NINH and one at TAN THOI.  A third outpost was repaired at HUI LON.  Four hundred and eighty-nine members of the RD/PF forces were given medical assistance during the period and approximately 1,600 individuals received Helping Hand commodities.  Housing for PF was constructed at TAY NINH and a playground adjacent to a PF nursery at DAU TIENG.  Support with commodities and barrier material in the TRANG BANG District was carried on during this period.  Drainage ditches were improved in the Dependent Housing area of HOC MON.

                    (g)     Friendship Council Meeting:  On 12 April 67, 2nd Bde conducted a Friendship Council meeting at TAN AN HOI (XT6412).
                    (h)     There were no Civic Action activities during Operations GADSDEN, WAIALUA, MAKALAFA and JUNCTION CITY.

                    (i)     During Operation MANHATTAN, approximately 275 refugees were evacuated to DAU TIENG Refugee Center.  They were supported with tents, clothing, toilet articles and building materials.

               (2)     Civic Action operational factors or activities contributing to Lessons Learned.

                    (a)     Observations:

                         1     Since February, the Division has participated in three major operations requiring a preponderance of forces to be employed in those operations.  With these elements out of Civic Action, a general trend downward on accomplishments was noted.

                         2     There was a willingness on the part of the population to take part in Self-Help  projects which is demonstrated in the construction of the PF outpost at TAN THOI.  The entire project was completed by voluntary labor from the hamlet.

                         3     (this line illegible)
during Operation MANHATTAN as well as a RF/PF (balance of line illegible).

                              a     Road and bridge construction continues to be a definite asset to Civic Actions.  Opening of the road from PHUOC VINH NINH to TAN HOA allows transportation to flow freely from CU CHI to VAU DUONG.

                    (b)     Recommendations:  None

          j.     (C)     Psychological operations (PSYOPS)

               (1)     Significant Organization and Unit Activities:                               
                    (a)     PSYOP activities were directed primarily in support of operations conducted by division elements in HAU NGHIA, LONG AN, BINH DUONG and (illegible) DINH Provinces.

                    (b)     A total of 22,463,900 leaflets were dropped and hand disseminated throughout the division operational area.  Thirty-five (35) leaflets were originated by G5 PSYOPS and produced by the 246th PSYOP Co to exploit PSYOP opportunities.

                    (c)     Aerial loudspeaker broadcasts conducted during the quarter totaled 225 missions for 142 hours of broadcast time.  Ground loudspeaker broadcasts totaled 25 hours.  An aerial loudspeaker set is presently being prepared to mount on an UH1D helicopter.  This will replace the set previously used on the H-23 aircraft.  The UH1D set will provide greater flexibility and consolidate the aircraft requirements for PSYOP as the UH1D will be utilized for both leaflet drops and loudspeaker appeals.

                    (d)     During the quarter, the G4 PSYOP section supported the following division operations:
                         1     Operation GADSDEN.     
                              2     Operation WAIALUA.
                              3     Operation MAKALAPA.
                              4     Operation JUNCTION CITY.
                              5     Operation MANHATTAN.

                    (e)     During the month of March, an ARVN PSYOP Team from the 30th Political Warfare Bn was placed in direct support of G4, PSYOP Section.  In April, a second ARVN PSYOP Team was released from the 196th Bde and placed in direct support of the 3rd Bde, 4th Div.  These teams have been instrumental in helping carry out the division PSYOP missions.  They have been used extensively in the following areas:

                         1     Interpreting.
                         2     Interviewing HOI CHANH.
                         3     Preparing leaflets.
                         4     Loudspeaker announcements and appeals.
                         5     Hand distribution of leaflets and posters.
                         6     PSYOP support of MEDCAPS.

                    (f)     A PSYOP campaign has been conducted along Highway #1 from CU CHI to GO DAU HA, offering rewards for information on VC mines.  So far, 3 Vietnamese civilians have given information regarding the locations of mines and have been paid rewards.

                    (g)     A bus mining incident occurred on 8 April 67 on Highway #1 between TRANG BANG and GO DAU HA, resulting in 18 civilians killed and 10 injured.  The incident was exploited, utilizing the ARVN PSYOP Team to broadcast messages showing that the VC were responsible and hand distributing leaflets showing that medical care had been given to the survivors by the GVN/US Forces.

                    (h)     Requisitions have been submitted by the G5 and each brigade within the division for a tape recorder and a Polaroid camera.  These items will be utilized for preparing tapes and making pictures for leaflets, thereby increasing the timeliness and credibility of our PSYOP material.

                    (i)     CHIEU HOI Program:  The CHIEU HOI Program continues to show improvement.  There is evidence that the program is beginning to affect the VC main force units.  During the month of April, two (2) former VC acting company commanders from the D-14 Bn and a VC tax collector from the MICHELIN Plantation rallied.  They cooperated by writing letters to be made into leaflets, allowing their pictures to be taken and recording tapes persuading their friends to rally.  They also provided useful information for improving our CHIEU HOI PSOP Program.  Most of the information listed under Para 2b (Lessons Learned).

               (2)     Psychological (PSYOPS) operational factors or activities contributing to Lessons Learned.

                    (a)     Observations:  The PSYOP Program continues to show more and more results as experience increases.  The number of leaflets disseminated and the amount of loudspeaker time has increased.  Effective themes are used to make our propaganda credible.  More hard core VC are rallying to the GVN, indicating that our propaganda themes are effective.  As more HOI CHANH are interviewed, the PSYOP efforts will be improved.  Ground loudspeaker and leaflet operations face to face communication and personal letters written by HOI CHANH to VC families have proven to be the most effective means of propaganda dissemination.

                    (b)     Recommendations:  See Lessons Learned.

          k.     Medical.

               (1)     Personnel and Supporting Medical Units.

                    (a)     The Division at the end of the reporting period was short four (4) Medical Corp Officers and one (1) Medical Service Corps Officer.  The shortage of physicians existed in the 25th Medical Battalion (2), and the headquarters and Headquarters Company, Division (2).

                    (b)     The 7th Surgical Hospital terminated all support by its personnel (who were infused into the 12th Evacuation Hospital) and moved out of the CU CHI base camp to assume another support mission.

                    (c)     The two primary medical facilities remaining in the CU CHI camp are the 12th Evacuation Hospital and the 25th Medical Battalion (-).  In April, however, the 25th Medical Battalion sent C Company to CHU LAI as part of a provisional task force, and now has only Headquarters and A Company and C Company in CU CHI.  B Company remains attached to the 4th Infantry Division at PLEIKU.

                    (d)     In March 1967, the 196th Infantry Brigade began participation in Operation OREGON for an indefinite period.  Medical support for garrison units at TAY NINH and combat units in the area was assumed by a clearing platoon (-) of the 25th Medical Battalion which was later replaced by a clearing company of the 9th Division.

               (2)     Training.

                    The 25th Medical Battalion conducted refresher training for all newly assigned corpsmen and initiated a plan wherein these personnel were infused into the Infantry battalions for a period of fourteen (14) days.  The instruction was met with enthusiasm and the plan was well received by the Support Command and the Infantry battalions as well.

               (3)     Preventive Medicine.

                    Health of the Command.  The health of the command continues to be excellent.  Malaria and Hepatitis cases remain at a low rate.  Venereal disease remained relatively consistent.  A rather high rate of diarrheal disease occurred in the month of April.

               (4)     Environmental Situation.

                    (a)     Water Supply.  The Division Preventive Medicine personnel consistently check the four water points in the CU CHI camp.  Each of the water points is operational and chemical analysis indicates the water supply to be excellent.

                    (b)     Waste Disposal.  Plans are being drafted to move the sanitary fill to a new location and to intensify the supervision of disposal of edible garbage.  The G4, in conjunction with the Post Veterinarian, is developing this program.

               (5)     Conclusion.

                    Medical support continues to be excellent.  The influx of new personnel into all medical facilities during the reporting period has not resulted in a setback of quality support, but rather has resulted in fresh energy and new ideas which has led to better medical service for the 25th Infantry Division.

               (1)     On 9 March, the Division Signal Office made distribution of a Staff SOI to be used at brigade and division headquarters.  To meet requirements of the respective staffs, the new staff SOI is on 8 X 10-1/2” sheets used in three-ring binders for ready reference and ease of understanding.

               (2)     On 13 April, the Signal Office presented to the USARV Signal Conference various topics of importance to this Division.  These included problems encountered in the frequent changing of radio relay frequencies, requisitioning of major items of radio relay equipment, the need for additional personnel, and air conditioning requirements for communications equipment.

          m.     Training.

               (1)     February 1967.  Training during the month of February 1967 continued, but at a slower pace due to the large number of units employed on Operation GADSDEN.  The following number of personnel attended the below division schools:

     Ambush Academy - No class in Feb     Replacement Training     423
     NCO Academy          138     Motor Officer Course     0
     Mines and Booby Traps     265     Generator Operator Course     16
     Explosives and Demolition     45     Military Justice Course     10
     Small Arms Maintenance     12     Mess Management Course     1

               (2)     March 1967.  The 25th Infantry Division Training Course has been increased with one additional course, Co Aidman course.

     Ambush Academy     161     Motor Officer Course     10
     NCO Academy          68     Generator Operator     12
     Mines and Booby Traps     390     Military Justice     10
     Explosives and Demolition     240     Mess Management     11
     Small Arms Maintenance     12     Company Aidman Course     34
     Replacement Training     1,657

               (3)     April 1967.  An additional course was added to the 25th Infantry Division Training, Tunnel Training Course.

     Ambush Academy     49     Motor Officer Course     0
     NCO Academy          65     Generator Operator Course     3
     Mines and Booby Traps     1,610     Military Justice Course     12
     Explosives and Demolition     101     Mess Management Course     2
     Small Arms Maintenance     1     Company Aidman Course     34
     Replacement Training     1,876     Tunnel Training course     32

In addition, New Equipment Training has conducted classes in the month of May on the AN/PSR-1 ANTI INTRUSION DEVICE.  Fifty-one personnel attended.  Also on (illegible) which allocations are received from higher headquarters, listings are as follows:

                    Recondo Course     33
                    Orientation Course     3
                    Helicopter Maintenance Course     15
                    IACAF Jungle Survival School     9

These figures of Non-Division Schools represents February, March and April.

     2.     (C)     Commanders Observations and Recommendations.

          a.     Observations (Lessons Learned)

               (1)     Personnel.

ITEM:  Turnover of personnel.

DISCUSSION:  Due to the units initial movement to RVN in April 1966, the Battalions experienced a heavy turnover of personnel in March and April 1967.  The units have had a hard time in keeping the combat effectiveness up and keeping the unit functioning smoothly due to this lack of experienced personnel.

OBSERVATION:  Rotation should be spaced so as to preclude any large turnover of personnel.  This can be done by:

                    (a)     Adjusting the DEROS to allow rotation over a 2 - 3 month period.

                    (b)     Inter-transfer of personnel between units to preclude both units having a large turnover; i.e., a Battalion with a heavy rotation of personnel in January could exchange 30 - 40% with a Battalion that has a heavy rotation in June or July.

ITEM:  Need for additional personnel in the Aviation Battalion.

DISCUSSION:  On 18 April, a Div Cir, 616-2, was received which stated that all outstanding MTO&E's requesting additional personnel had been disapproved and that the Battalion should prepare itself to function within the confines of the “E” series TO&E.  Examination revealed dire need for additional people if the Bn was to continue to operate in an effective manner.

OBSERVATION:  This unit, as far as can be determined, is not organized like any other aviation unit, either divisional or non-divisional, in RVN.  A general rewrite of the Aviation Battalion TO&E is urgently needed to establish a logical structure from which the Aviation Battalion can continue to provide support for the Div without straining its existing assets.

ITEM:  Replacement of Aviator Personnel to maintain combat effectiveness.

DISCUSSION:  Aviators have been rotated prior to replacements being assigned to the unit.  When new aviators are assigned, a period of approximately fifteen days is required to train personnel to assume the duties of those who have departed.

OBSERVATION:  Replacement personnel should be programmed to arrive a minimum of 15 days prior to the departure of an aviator in order to maintain combat effectiveness.

ITEM:  Availability of Operations personnel of proper MOS to replace personnel who are to depart.

DISCUSSION:  During the last three months, all Company Operations personnel have rotated with no qualified personnel for replacements.  At present, all personnel working in Operations, with the exception of one, are on-the-job trainees.

OBSERVATION:  A concerted effort should be made to replace personnel in critical MOS's prior to departure to maintain a proper continuity in these slots.

               (2)     Operations

ITEM:  Deliberate versus Hasty Search.

DISCUSSION:  Deliberate and Hasty Search Ops both have distinct advantages and disadvantages.  Generally, the Hasty Search Op is planned to move through an AO quickly to catch VC off guard.  The Deliberate Search is planned with the idea of destroying VC food, supplies, equipment, and fortifications.

OBSERVATION:  The initial phase of an op should consist of Hasty Search of the entire AO, preferably by the use of highly mobile units such as Mech or Heliborne forces.  Subsequent phases should employ phase lines which require units to do a thorough job prior to moving on.

ITEM:  Detection of Mines.

DISCUSSION:  A rain, especially a relatively hard one, will uncover mines laying near the ground surface, particularly in open areas and along roads.

OBSERVATION:  Following heavy rains, maximum advantage should be taken of greater mine detection capability resulting from mines being uncovered to recon future routes, CP locations, etc.

ITEM:  VC Contact.

DISCUSSION:  Calling in Arty/Mortar fire and/or airstrikes against light contact even though some element of the unit may have heavy contact and several serious casualties, causes considerable delay to counterattack plans, usually resulting in loss of VC contact.  These fires should be called for immediately, but at such distance that they seal off the objective area and initially serve as a block to withdrawing VC.

OBSERVATION:  Light enemy contact must be met with aggressive action.  Arty, mortar, and air fires should be called for immediately but at a distance which will seal off the area from VC reinforcements and block VC routes of withdrawal.

ITEM:  Perimeter Defense.

DISCUSSION:  A possibility exists that a vehicle (or vehicles) on a perimeter could be overrun and its .50 Cal MG turned on other carriers.

OBSERVATION:  Each vehicle inside the outer perimeter must also be assigned a sector of fire which includes the friendly carriers within that sector in the event they are overpowered in an attack.

ITEM:  Personnel Riding in Carriers versus on Carriers.

DISCUSSION:  There are distinct advantages and disadvantages to both riding in carriers and on carriers.  Generally, riding on carriers results in fewer casualties from RPG-2 rds and more rapid response to enemy contact; however, it also results in more casualties from command detonated claymores and sniper fire.

OBSERVATION:  There should be a fixed policy on riding on/in personnel carriers.  The local commander must determine whether the greater threat is from RPG-2 rds or from command detonated claymores and booby traps.  Once he decides on the most probable threat, he should place his men accordingly.

ITEM:  Mutually Supporting MO Bunkers.

DISCUSSION:  In a human wave frontal assault, VC were able to overrun 2 - .50 Cal MG bunkers.  These bunkers, despite their heavy fire power, are not capable of withstanding a heavy frontal assault.

OBSERVATION:  MG Bunkers are the first objectives of a VC human wave attack.  They must be heavily protected by concertina wire, sand bags and fortifications.  MG bunkers must be mutually supporting and must have FPL's immediately in front of the adjacent MG bunker.  MG bunkers must have M16 claymore mines at least 2 rows deep and 3 rows wide in front of them to break up assaults.

ITEM:  Defensive Arty Concentration.

DISCUSSION:  DEFCONS are an excellent means of providing rapid, close, and accurate arty fire w/o time consuming adjustments.  When properly used, the DFEFCONS can provide instant support and first rd hits on advancing enemy force.

OBSERVATION:  DEFCONS must be fired to within 100 meters of the FPL.  To do this, trps must be in protective positions while firing.  DEFCONS must be fired at all quadrants, a minimum of 4 or more, depending on the size of the unit involved, and should cover all avenues of approach and all dead space.  DEFCONS must be fired in at different intervals, at a minimum every other day, to make allowance for difference in guns and movement of perimeter.  Irregular firing of DEFCONS during the night insures that the VC cannot approach FPL.

ITEM:  Small Unit Sweeps.

DISCUSSION:  Slow ground sweeps in a single direction results in VC detecting the axis of advance and fleeing the zone of action.

OBSERVATION:  Small unit sweeps should be a two phase op.  The first phase is a fast violent attack to surprise the VC.  The second phase should be a meticulous search of all likely hiding places after the zone of ops has been effectively sealed.

ITEM:  Selection of a Defensive Position.

DISCUSSION:  A major river is a dangerous obstacle on which to have a perimeter.  Rivers are often bordered with heavy vegetation that limits observation.  The obstacle hampers the movement of friendly troops and offers protection for snipers firing from across the river.

OBSERVATION:  Select defensive perimeters with small obstacles with good visibility and fields of fire.  The inside of the perimeter should afford cover and concealment.

ITEM:  Canal Crossing.

DISCUSSION:  Crossing canals at previously constructed sites often results in booby trap casualties.

OBSERVATION:  Construct multiple crossing sites.  Secure the far banks and flanks and cross well dispersed, with at least five meters between individuals.  A good rule is one man on the far bank, and in the water, and one on the near shore.

ITEM:  Helicopter Resupply.

DISCUSSION:  Shuttling helicopters over long distance resupply routes from base camp to the forward combat units results in long turn-around times when the helicopter is not being profitably used.  This also increases the time needed for resupply ops and forces the forward unit to halt combat ops early in the afternoon.

OBSERVATION:  Moving supplies by convoy to the Fire Support Base early in the day cuts turn-around time to a minimum and permits maximum use of daylight hours for combat ops.

ITEM:  Aviation Unit Standard SOP.

DISCUSSION:  Small differences in aviation unit SOP on such things as formations, leading, signal, smoke, etc., can mean the difference between success and confusion on combat airlifts.

OBSERVATION:  A Vietnam-wide SOP on heliborne Ops which spells out minor points but allows those points to be changed when the situation dictates would allow for more effective Ops with all aviation units.

ITEM:  Hand Grenade Employment and Safe Distance When Destroying Bunkers.

DISCUSSION:  Mines and booby traps in VC bunkers often create a larger explosion than expected when demolitions are employed to destroy the bunker.

OBSERVATION:  Hand grenades should be thrown in all bunkers after visual inspection.

ITEM:  Immediate action after an APC hits a Mine.

DISCUSSION:  When a Mech unit remains in place after one of its vehicles hits a mine, it lays itself open to VC AW and anti-tank fire.  Minefields are often covered by fire.  If the unit halts in column, it is difficult for medical personnel to move their APC up to the mined APC.

OBSERVATION:  Once an APC strikes a mine and receives fire, the remaining vehicles should bring fire to bear on enemy positions, maneuver toward those positions, and post dismounted security elements forward.

ITEM:  Nightly firing of Final Protective Fires.

DISCUSSION:  Controlled firing of the Co FPF just after dark, before the listening posts move into position, followed by a Bn critique proves to be very effective.  The action:  (1) Verifies weapons positioning, (2) clears the wood line of VC prior to patrol deployment, (3) gives the men confidence in their defensive fires.

OBSERVATION:  Final protective fires should be fired nightly and adjusted as necessary.

ITEM:  Satelliting of ARVN to US Units down to Platoon Level.

DISCUSSION:  Twice during Op JUNCTION CITY, the 1st Bn (Mech), 5th Inf operated with ARVN Units.  Companies were satellited to US Companies, and Platoons worked together.  The spirit of aggressiveness and cooperation far exceeded previous Ops where ARVN units worked toward the same mission but in separate areas.  Results were gratifying.

OBSERVATION:  When the VS Commander agrees, US-ARVN units should be paired down to Platoon level and controlled by a joint Headquarters at each level.

ITEM:  Use of Wiretap Teams.

DISCUSSION:  Several times in Ops of the 1st Bn (Mech), 5th Inf, VC commo lines were discovered but high HQ8 indicated that only specially trained teams should be allowed to tap them for intelligence material.  The time required for such teams to arrive in the area is long.  The question remains unanswered on whether an inexperienced team tap would produce an audible click in the line, and if it did, would a VC operator recognize the sound.

OBSERVATION:  A written policy should be published concerning wiretapping of enemy lines.  Any evaluation of the problem should consider immediate tactical value of intelligence gained in relation to the chance of compromising the tap.

ITEM:  Small VC Mines may be Augmented with Larger Explosive Charges.

DISCUSSION:  On important roads, small exposed mines have been found to be connected with concealed large explosive charges.  In many cases, if the apparently small mine is detonated, the supplementing explosion can cause craters, unexpected damage, and casualties.

OBSERVATION:  In areas which should be preserved from damage, all mines should be carefully examined before destruction.  Care must be taken in analyzing the resultant damage which might occur if the mine is, in fact, used as a detonator for a larger mine.  Disarming and removal of mines should be accomplished whenever possible.

ITEM:  Routes May be Mined Shortly After Use.

DISCUSSION:  When units return on the same route previously used, they have found that mines have been laid in the interim.  On a recent Op, one unit returned over a route they had cleared only six hours earlier and found that mines had been laid in the fresh tracks.

OBSERVATION:  When feasible, exit an area over a route different from that used to enter.  When this is not possible, use mine detectors and be alert to the likelihood of recent minings.

ITEM:  Cross Country Mobility of M42 (Twin 40mm SP).

DISCUSSION:  The M42 unit can be effectively employed with Mechanized and Armored Cav units operating in open areas of rice paddies and hedge rows.  Their use in jungle areas or in dense undergrowth is not recommended.  Optimum deployment is two M42's per platoon of supported units.  The M42's direct fire capability for counter fire at night.  Logistic support for POL and ammunition is critical.  Maximum range of M42 cross country is (illegible) miles as fuel consumption is 2-1/2 gal per mile.

OBSERVATION:  Direct support missions of Mechanized and Armored Cav units are within the capability of the M42 weapons system.

ITEM:  Security of Disabled Vehicles.

DISCUSSION:  An M55 (2-1/2 ton trk mtd Quad .50 Cal MG) was mined, resulting in 3 WIA and destroying the vehicle.  Ten minutes after the incident, the crew received SA and AW fire from an est Sqd of VC.  The alertness and aggressive action of the crew forced the VC to break contact.

OBSERVATION:  The establishment of security must be done simultaneous with the care of wounded after a vehicle is disabled.

ITEM:  Fire Coordination Lines.

DISCUSSION:  Coordination of fires adjacent to other units requires extra precaution and coordination.

OBSERVATION:  Direct VHF Communications between adjacent artillery clearing Hqs is imperative.  There should be no middle man in the clearing process.

ITEM:  Clearance of Fire Adjacent to Fire Coordination Lines.  

DISCUSSION:  During a recent Op, two Bdes shared a mutual boundary designated as an FCS.  One Bde policy restricted fires within 500 meters of friendly position.  They often refused to clear fires in the adjacent Bde area if those fires would fall within 500 meters of their positions.

OBSERVATION:  FCL's should be treated as defined in PM 6-20-1, i.e., a coordination line, not a clearance line or permission line.  No other units should have the authority to deny fires within another unit's area of Op, provided the effects of the fire will not go into the other unit's area.

ITEM:  Employment of Artillery Searchlights.

DISCUSSION:  The employment of searchlights in support of perimeter defense is new to many tactical units and their deployment and use require special techniques.

OBSERVATION:  Searchlight missions require the same coordinating procedures as fire missions, i.e., adjacent units must be consulted.  Also, the lights must be laid for direction with direct communication to a light DC.  Lights should have alternate positions and be moved nightly.

ITEM:  Flights near Defensive Fortifications.  

DISCUSSION:  On 14 Jan 67, an aircraft was assigned the mission to defoliate the perimeter of an ARVN compound.  While flying at approximately 30 feet in performance of this mission, a friendly claymore mine was detonated.  The mine was probably triggered by the aircraft rotor wash and resulted in the aircraft receiving approximately 30 holes through the skin and the crew chief being wounded slightly in the hand.

OBSERVATION:  Careful consideration must be given to any mission which is to be performed in the vicinity of defensive fortifications.

ITEM:  Obtaining Ground Clearance for Aviation Operations.

DISCUSSION:  The amount of coordination required to obtain ground clearances to conduct Army Aviation Aerial Fire Support and Firefly type Ops takes up a considerable amount of time if accomplished on a day to day basis.  Whenever possible, Ops of this type should be preplanned to cover longer periods of time and clearances obtained as much as a week in advance.  In this matter, advance notice is available to all concerned and more effort can be directed to detailed planning.

OBSERVATION:  In planning aviation support, mission type orders should cover longer periods of time.  Clearances can then be obtained earlier, cover a longer period of time and require less time and effort to coordinate.

ITEM:  Concertina Wire.

DISCUSSION:  Triple concertina defense wire, when properly used and installed, is very effective in preventing infiltration and frontal assaults on friendly positions.  A single strand of concertina can be easily breached and must be (illegible) to triple strand.  Triple strand wire, if not properly secured, can be infiltrated by individuals.

OBSERVATION:  Triple concertina defensive wire must be:

                    (a)     Securely staked down with 8' and 4' (illegible) pickets and strung with barbed wire.  This prevents the wire being lifted and infiltrated.

                    (b)     Concertina must be minimum of 50 meters from the nearest friendly elements to prevent hand grenades being thrown in from in front of the wire.

                    (c)     Concertina must be covered by AW fire at points of easiest access.

                    (d)     Trip flares and noise making devices should be used to provide warning of any attempt to break the perimeter.

                    (e)     Booby traps and mines can be employed in front of and under the concertina wire.  Those areas must be covered with AW fire.  Permission to booby trap must be received from 25th Inf Div CO.

               (3)     Training and Organization.

ITEM:  Formation of provisional combat team within a support-type unit enhanced morale and improved efficiency.

DISCUSSION:  Some soldiers in the Sqdn's Hq & Hq Trp did not feel that their administrative and logistical duties effectively contributed to the U.S. effort in RVN, and several had requested reassignment to line trps.  The line units provide an ambush patrol outside the base camp's perimeter every night, along with other operational missions.  Volunteers were assembled from the HHT and undertook additional training for three weeks.  The twenty-five persons who persevered were formed into a provisional unit which participates in an ambush patrol at least once per week, relieving the line units that night.  This unit is known locally as “McCormack's Raiders” after the HHT Commander.

OBSERVATION:  Formation of volunteers from HHT into a provisional unit has afforded them the opportunity to actively participate against the VC, and has greatly increased unit pride and Esprit de Corps.

ITEM:  Rotation of Bn Personnel.

DISCUSSION:  Over 50% of the enlisted personnel and 80% of the officer personnel were rotated to CONUS in the past 90 days.  This “rotational” hump was completed while the Bn was involved in Op GADSDEN and JUNCTION CITY.  The program of cross training personnel, coupled with the prompt requisitioning and arrival of replacements was a major factor in the successful accomplishment of the Bn (illegible) in support of combat operations.

OBSERVATION:  That continued emphasis be placed upon cross training of personnel and prompt requisitioning of replacements.

ITEM:  Div MARS Station.

DISCUSSION:  There exists the requirement for more frequencies to be made available for use by the 25th Inf Div MARS Station.  This station operates a net which consists of five stations.  At the present time, two frequencies are available that can be used daily and one additional frequency that can be used every other day.

OBSERVATION:  If two more frequencies were made available, the number of phone patches could increase, resulting in a greater number of Div personnel receiving benefit from this facility.

ITEM:  Division Signal School.

DISCUSSION:  The Div Signal School makes available training classes on use of the codes and secure voice communications equipment to all units within the Div.  The following are the number of classes conducted and personnel who attended:

               (a)     February:       4 Classes       7 attended
               (b)     March:     11 Classes     67 attended
               (c)     April:     11 Classes     74 attended

OBSERVATION:  Attendance at this school is not mandatory but is provided for the benefit and convenience of the Div.  Units send personnel to the Div Sig School when operational commitments permit.

ITEM:  Destruction of Duds and Mines.

DISCUSSION:  Much time can be lost by having the finding unit (usually the lead element) destroy duds and/or mines.

OBSERVATION:  Mines and duds should be marked and prepared for demolition by the finding platoon, but actually blown by a following element.

ITEM:  Use of Grappling Hooks.

DISCUSSION:  Grappling hooks with long ropes can be used effectively to check enemy mines, equipment, road blocks, brush and trees from roads, etc., for possibly booby traps.

OBSERVATION:  Grappling hooks with long ropes attached should be carried (1 per platoon) for use in blowing booby traps.

ITEM:  Test Firing Weapons.

DISCUSSION:  Patrols desire to test fire their weapons frequently but are not always provided with a range without request.  This is also true of Hqs Personnel.

OBESERVATION:  After due coordination with adjacent units an/or ARVN, a range and time can be established for test firing of weapons.

ITEM:  Use of Claymore Mines.

DISCUSSION:  Berms, ditches, folds in the terrain, etc., often preclude claymore mines from being effectively employed.

OBSERVATION:  Dead space can sometimes be covered by placing claymore mines in trees, on poles, etc.  The Lesson Learned is to use imagination in the placing of claymores.

ITEM:  Gasoline Operated Chain Saws.

DISCUSSION:  Due to restrictions on selection of Arty position areas, it is often necessary to remove trees and other obstacles to provide required fields of fire or to reduce site to mask.      

OBSERVATION:  Gasoline operated chain saws should be included as part of the Arty firing btry MTOE.

ITEM:  Aviator Training.

DISCUSSION:  During the month of Feb, this unit only participated in four combat Ops.  This occurred during a period of maximum aviator change-over, so that when the end of Mar arrived, A/25 only had eleven fully qualified aircraft commanders out of a required total of twenty-five.  To be considered fully trained by this unit's SOP, the aircraft commander must be signed off by an instructor pilot after he has successfully participated in a minimum of three combat assaults as an aircraft commander.

OBSERVATION:  A minimum of fifteen combat assaults monthly is considered essential to maintain aviator proficiency and to train new aviators.  When the turnover of personnel increases during a given period of time, consideration must be given to the unit's CA commitment so that aviator proficiency does not decrease.

ITEM:  Lack of (illegible)-Secured Ranges for Gunnery Training.

DISCUSSION:  The only available ranges have been over hostile territory, making it necessary to use two armed helicopters in these areas.  The lack of flyable aircraft in sufficient numbers to accomplish this has made proper and continuous training impossible.

OBSERVATION:  The availability of a range or a local secure area would facilitate the use of only one aircraft to accomplish gunnery training when two aircraft are not available.

ITEM:  Flight Sections.

DISCUSSION:  Under our present TOE, the General Support Company consists of a General Support Platoon, containing a (illegible) Section and a (illegible) Support Section.  This causes some aviators to fly an excessive number of hours, while others fly a lesser amount.

OBSERVATION:  By dividing the aviators into 4 flight sections, controls can be established governing the number of hours and types of missions that each aviator would fly, thus giving each aviator a chance to fly different type aircraft and a more rounded experience in different type missions.

ITEM:  Organic Armed Helicopters.

DISCUSSION:  Co A does not have the capability of immediately responding to airmobile lift requirements because of the lack of an organic armed helicopter platoon.  The general support requirement placed on Co B by the Div scattered Ops precludes rapid response.  The armed helicopters in B/25 provide fire support to ground elements, night surveillance and interdiction missions, convoy cover, counter mortar suppression and medical evacuation/resupply aircraft escort cover.  Div requirements for gunship support on these missions presently tax B/25's capabilities to the fullest.

OBSERVATION:  With an organic armed platoon, A/25 would not have to wait for the recall of B/25 gunships or the attachment of fire teams from other units in the Corps area.  Teamwork between the lift aircraft and the gunships is absolutely essential for a successful airmobile op.  At present, this team action must be coordinated for each and every assault.  With organic gunships coordination would be a matter of standard operating procedure, and provide the (illegible) proven capability now employed by combat Avn Bn Airmobile Companies.

ITEM:  Requirements for TO&E Augmentation.

DISCUSSION:  This unit currently is organized under TO&E 1-75E as directed by (illegible), Hq, 25th Inf Div.  No augmentation has been provided to allow for increased activities initiated by combat requirements.

                    (a)     Under original Div TO&E, the maintenance Bn was staffed to provide E Co, DS maintenance for Aviation support.  At that time, Div had only the general support company plus separate aviation sections to furnish aviation support to the Div.  Co A, Airmobile (Lt) was added in May 65.

                    (b)     US Army manning level augmentation criteria for establishing maintenance personnel requirements indicate far greater maintenance personnel strength is required to furnish the aircraft availability and utilization which the Inf Div has proven necessary for sustained Ops in RVN.

                    (c)     Firm commitment for sufficient pilot strength is not available at company level, although the additional pilots required to fill both pilots seats in 25 aircraft appear on TO&E 1-77E as augmentation Para 08 Line 01.

                    (d)     No action has been approved to allow 25 door gunner positions or to assign rank structure for those individuals.

OBSERVATION:  Tactical necessity for increased maintenance capability has been proven for over 4 years by airmobile companies (Lt) thru flying hour programs, A/O availability and overall mission capability.  Those units have assigned AO maintenance detachments as outlined in TO&E 29-5000.

RECOMMENDATION:  Recommend procuring a like maintenance Det for Co A, 25th Avn Bn.  Further recommend necessary action be initiated to provide complete operational TO&E with necessary augmentation approved thru CO.

               (4)     Intelligence

ITEM:  Innocent photographs can provide enemy intelligence with valuable information.

DISCUSSION:  In Feb 67, three VC low level agents were captured on the 25th Inf Div Base Camp.  Their apprehension was based on three photographs that were captured from an unidentified VC intelligence unit.  The photographs contained the pictures of five indigenous laborers employed on the base camp whose features had been obliterated, apparently by being burned out with a cigarette.  The background of the photographs contained figures listing distances in meters from Arty/registration points, as well as identification markings on various military equipment and structures.  During interrogation, the three agents admitted that the photographs had been taken by their Bn supervisors to do a favor to the agents and that the measurements had been written in the photographs at the request of their handler, who had specified the point at which to take the measurements.

OBSERVATION:  All personnel, and especially those assigned to duties supervising indigenous employees, should have the security risk inherent in even innocent photographs brought to their attention.

ITEM:  The necessity for furnishing a complete, accurate Captive Card (MACV Form 340) with every detainee.

DISCUSSION:  In many instances, detainees are evacuated for interrogation without a Captive Card or with one which contains fragmentary, incomplete or erroneous information.  It is difficult to gain the upper hand during the initial interrogation when this occurs.  It is, therefore, essential that capturing units complete individual Captive Cards IN THE FIELD, providing the DETAILS of the capture of every person detained.  In some cases in the past, personnel of capturing units Hqs have attempted to complete capture tags after the arrival of the detainee at the Div PW Collecting Point.  Naturally, the lack of first hand information concerning the circumstances of the capture of the individual leads to serious omissions of vital information.

OBSERVATION:  Every member of the individual line units should carry and know how to complete Captive Cards of detained persons.

ITEM:  Visits of Unit S2's.

DISCUSSION:  Past experience has shown that timely visits by S2's to the Order of Battle (OB) Section, 25th (illegible) Det, have been valuable to both parties.  The free exchange of intelligence information inherent in their visits eliminates the possibility that intelligence may not reach the S2 and allows clarification in detail of intelligence holdings.  Extensive visual aids ((illegible) maps, photos, charts and overlays) maintained at the (illegible) Det enable the S3 to relate his information to the overall situation in the Div TAOR.  All intelligence sources available to the (illegible) are analyzed and related to the specific area of interest of the S2's unit.  The S2, in turn, provides detailed information on areas in which his unit has operated.  This information plus the results of exploitation of intelligence provided by the OB Section are of significant value to the overall intelligence program.

OBSERVATION:  Frequent visits of Bde and Bn S2's to the OB Section are of value to the overall intelligence program in general and the continued (illegible) in particular.

ITEM:  H & Y Target Acquisition with SLAR Aircraft.

DISCUSSION:  A moving SLAR return in the vicinity of a suspected VC base camp indicated that the camp might be occupied.  Arty fire was placed on the base camp and large secondary explosion resulted.  A moving return on a road or river can be engaged by firing along the road or river or by firing at known or suspected crossing of off loading sites in the vicinity.  A return in the vicinity of a planned concentration can be fired upon almost immediately.  SLAR returns which require comparison with other available intelligence to determine proximity to known installations or activities can generally be fired upon within 25 minutes after sighting.

OBSERVATION:  In flight spot reports from Army MOHAWK SLAR aircraft can provide lucrative Arty H & I targets.

ITEM:  Use of MI Teams at Bn Level.

DISCUSSION:  Military Intelligence Personnel remain at Bde OP locations during Ops.  MI Teams could collect more timely and accurate information if they were in the field with maneuver elements.

OBSERVATION:  MI Teams should be available to company sized units on call for on-the-spot exploitation of captured documents, personnel, and materials.

ITEM:  Rapid and accurate reporting of VC Structures and Materials.

DISCUSSION:  Because of the nature of many Ops which require company elements to maintain their momentum, there is little time for Bn Intelligence Personnel to conduct on-the-spot investigation of discovered installations or materials; the company must move on.  In order to obtain timely and accurate information about enemy structures and materials, the company should be prepared to conduct its own inventory of materials and to make diagrams of structures.

OBSERVATION:  Each company should assign a team to sketch enemy fortifications; a second team could conduct an accurate inventory of captured material.  This information could be quickly passed to Bn, and with little delay the company could continue to move.

ITEM:  H & I Fires may prevent VC recovery of bodies.

DISCUSSION:  When an ambush patrol engages VC during contact but does not subsequently leave its position and search the target area, the VC usually return before daylight and remove the bodies.  Recently, a unit called frequent harassment and interaction (H & I) fires into the killing ground until daylight and then was able to move out and identify the VC losses.

OBSERVATION:  VC knowledge.  When H & I fires will fall on the killing ground they discourage recovery effort and enable an accurate body count.

ITEM:  Aviation Spot Report Net.

DISCUSSION:  Division Aviation Units fly all over the Div on routine missions daily.  Continuous surveillance of the area by aircraft on routine missions can result in significant intelligence information which would otherwise go unnoticed.  Currently, here is no central reporting facility for aviation spot reports.  Each aircraft reports to its parent unit and the reports are then routed up through channels, delaying the arrival of this information at the (illegible).  The aviation Bn used its flight following facility, Clipper Control, as an aviation spot report net monitored by the Bn S2, who, in turn, phones significant reports to the G2.

          The usefulness of the system was pointed up when an aircraft on a courier mission reported sighting what appeared to be a mined bus in Hwy #1, diverted to the scene and successfully evacuated several seriously injured civilians.

OBSERVATION:  An Aviation Spot Report Net or Intelligence Net monitored by Bn personnel would facilitate a much faster dissemination of timely valuable information reported by aircraft over the Division TAOR.

ITEM:  Booby Traps.

DISCUSSION:  In order to provide protection for base areas, caches, hospitals and LOC, the VC will heavily mine and booby trap an area or an avenue of approach into an area.  The VC have been known to have an area prepared with (illegible) booby traps and, when forced to leave an area, will attach trip wires or otherwise arm the booby traps.  Bunkers have been known to have mines or booby traps mounted just inside the entrance where an attempt to enter will cause detonations.

OBSERVATION:  Engr mine detector and (illegible) teams can save much time and (illegible) casualties while traversing a mine field or booby trapped area.  Mine detectors should be used in the entrances of all bunkers, fortifications and VC structures.

                    (a)     (illegible) dispersion will lessen chances of large numbers of casualties from a single booby trap.

                    (b)     Where practical, booby traps should be blown in place either with ammo or by use of a grappling hook to detonate the booby trap.

               (5)     Logistics

ITEM:  Potable Ice Supply.

DISCUSSION:  The Potable Ice supply at CU CHI is inadequate.  Two 15 ton capacity ice plants at base camp are operational, but only produce 25 tons per day.  Requirements are for approximately 66 tons daily.  Because of lack of adequate potable ice and lack of adequate refrigeration equipment, 1st Log Comd supplements the potable ice produced at CU CHI with non-potable ice on government contract.  This non-potable ice, contaminated with bacteria from human waste, is a constant health hazard as continual supervision is needed to prevent mixing of potable and non-potable ice at the user level.

OBSERVATION:  Additional ice plants need to be built at Camp CU CHI for production of potable ice.  Two are scheduled for construction within 4 to 5 months.

ITEM:  Operation of ASP at CU CHI.

DISCUSSION:  An ammunition supply point is presently operated at Camp CU CHI by the DAO, 25th Inf Div.  The Inf Div (illegible) does not authorize personnel or equipment for purposes of operating an ASP.  Due to the relatively isolated geographical location of the Div in relation to Class V stocks at depot, it is necessary that Class V be stocked at CU CHI to allow quick response to any operational necessity.     

OBSERVATION:  Operation to include providing of personnel and equipment of the CU CHI ASP should be taken over by elements of 1st Log Comd.

ITEM:  Air Drop Resupply.

DISCUSSION:  During the period 21 Mar - 7 April 67, the 196th Bde was largely dependent on air drop resupply while participating in its floating brigades operation during Operation JUNCTION CITY, Phase III.  A total of 613.3 short tons of Class I, III, and V supplies were airdropped at eight different locations.

OBSERVATION:  Inter-service cooperation was excellent.  Response by Air Force crews to (illegible) changes in drop zones and their overall delivery accuracy and timeliness was exceptional.  Though Air Force and Logistical assets were limited and stretched to the (illegible) during this period, the ground commander was successfully resupplied and in a position to devote his full energies to his tactical mission.

ITEM:  Aircraft Refueling Capabilities.

DISCUSSION:  During The logistical planning phase prior to the conduct of Op (illegible), (conducted 8 Apr - 22 Apr 67) it was established as a valid requirement that two (illegible)-ports were needed in the operational area.  These (illegible)-ports were needed for (illegible) resupply.  Detailed discussions and studies resulted in the conclusion that none of the units of the Div have the personnel or equipment capability to operate (illegible).  (Illegible) refueling points at field locations.  (Illegible) refueling points at field locations, (illegible).  Aviation Bn and the aviation section of Bde Hqs do not provide the (illegible) to operate the (illegible)-ports in Bde trains area or (illegible).  The problem was solved in this Op by the MACV advisory element located nearby to the operations are voluntarily operating the (illegible) refueling point by providing both personnel and equipment.

OBSERVATION:  The (illegible) of the (illegible) was the concept of combat service support for the Div (illegible) aircraft refueling must be given detailed study with possible resultant requests for (illegible) of TOE's and combat service (illegible).

ITEM:  Oil Analysis Program Reports.

DISCUSSION:  Oil analysis reports indicate that gear box and engine (illegible) and (illegible) Aircraft are contaminated from dirt.

OBSERVATION:  After extensive research, random sampling of the oils throughout the Div, it was decided that by reducing the time interval of oil changes required by applicable Technical Manuals the problem was largely solved.

ITEM:  Div Photo Lab.

DISCUSSION:  During the tactical combat photographic missions, experience has shown that certain photographic equipment currently being used by the Div Sig Bn is not satisfactory.

OBSERVATION:  The (illegible) and MS-AA cameras are too complex and fragile for use in combat photography.  The (illegible) rate for this equipment and lack of replacement parts reduces the capability of the Div Photo Section.  There is a lack of working space in the dark room AA/(illegible), which materially inhibits the Op of this facility.

ITEM:  Medium Size Jungle Fatigues.

DISCUSSION:  Non-availability of medium jungle fatigues.

OBSERVATION:  Due to the rapid turnover of personnel and high percentage of direct (illegible) due to (illegible) wear and tear, (illegible) overage of authorized storage of jungle fatigues, size medium, should be kept on hand.

ITEM:  Resupply to Fwd Units.

DISCUSSION:  Resupply to fwd units is at best time consuming process, rations, water, ammo and misc gear must be taken in every night and extracted in the morning.  In addition, in inundated areas where no cover is available filled sandbags are required to provide (illegible) positions for the troops.

OBSERVATION:  Where (illegible) and tactical situation allow (illegible) CH-47 is the fastest and easiest method of (illegible) resupply.  One sortie of CH-47 carries as much as 5 - 8 times the load of a (illegible)-12.  Loads can be slung and dropped into the area w/o causing a lot of loading and unloading problems.  By using CH-47 resup time was cut by 2/3 and exposure of troops and equipment to enemy fire reduced to the min.  To properly use the Ch-47 capabilities, additional slings and cargo nets are required in the basic TO&E equip.

ITEM:  Dry-cell batteries no longer possessing full power can be re-used in equip required reduced quantities of energy.

DISCUSSION:     The reason life of batteries occurring in RVN (illegible) it considered that they be used with (illegible) efficiency.  When no longer powerful enough to operate the (illegible) switchboard, the BA200 six volt battery can still power (illegible) lantern.  BA30 batteries no longer powerful enough to operate an AA/(illegible 35 (illegible) unit are still suitable for use in (illegible) flashlights.

OBSERVATION:  While re-used batteries do not last as long as fresh ones, they perform satisfactorily for a reduced length of time and ensure the batteries complete use.

ITEM:  Climate conditions in RVN indicate treatment of fungal dermatitis with GRISEOFULVIN.

DISCUSSION:  The fungal dermatities are among the most common problems seen on rolling sick call.  (illegible) in that category are tinea (illegible), tinea (illegible), epidermaphytic infections, and non-specific external otitis infections.  Whereas local medications have in the most part proven to be useful in treating these conditions, the moist dusty climate encountered in VN has (illegible) to (illegible) treatment by this method both impractical and prolonged.

               Consequently, all patients presenting any of the above problems are begun on Griseofulvin 100 mg (illegible), as well as local antifungal medications.  On this combined regiment, there has been a remarkable increase in cure rate, and decrease in time of treatment necessary.  The patient is put on a one week course of Griseofulvin and there have been no cases to date of toxic hematological reactions to this dose regimen.  

OBSERVATION:  Griseofulvin has proven to be a valuable first-line treatment of the fungal dermatitis encountered in RVN.

ITEM:  Rough handling of 2.75 M.E. Rocket causes rocket motor explosions.

DISCUSSION:  It has been determined that dropping 2.75 Rockets will separate the propellant, causing the propellant to burn to the separation and explode.  Rough handling before or after the warhead and motor are assembled will cause the propellant to separate.

ITEM:  Supply Problems.

DISCUSSION:  In too many cases it has been necessary to conduct a physical search of (illegible) warehouses to determine if a needed item is on hand.  Once this is done, requisitions are then carried from one office to another and unit pick-up is effected.  This (illegible) is usually caused when the requesting unit encounters incomplete or invalid advice codes on follow-ups, or when there are long delays in obtaining high priority items.

OBSERVATION:  It appears that often it is necessary for more impetus to be provided at user level in order to cause the supply system to function.

ITEM:  Mid-Day Water Resupply.

DISCUSSION:  Due to the high temperature in late March and early April, it was found that the combat effectiveness of the trps was lowered if they were restricted to two canteens of water peer day.

ITEM:  Aerial Broadcast.

DISCUSSION:  Aerial broadcasts have proven to be an effective way to reach VC for propaganda in support of GVN ops.  To further the PSYOP program an aircraft equipped with loudspeakers and an aerial observer was employed for 4 nights at the FILHOL Plantation - PHU HOA DONG area.  The “No-(illegible)” flights (illegible), oriental music and CHIEU HOI appeals.  The aerial observer was included to call arty fires on any VC shooting at the acft.

OBSERVATION:  The “No-(illegible)” flights proved eff in that they read sniper fire on a number of occasions and that the PHU HOA DONG residents were made very much (balance of paragraph illegible).

ITEM:  Utilization of Jeep mounted loudspeakers.

DISCUSSION:  Organic to every Inf Bn is one loudspeaker set capable of being mounted on a ¼ ton truck for mobile use.  This equipment was used to make announcements of MEDCAPS and for PSYOPS.  It was also used in support of seal and search missions and by village chiefs during PSYOPS.

OBSERVATION:  The jeep mounted loudspeaker has proven to be the most effective way to reach large groups of people at the same time.  Allowing the village Chief to use this equipment, with US driver and US personnel present, may increase his stature in the village and gain more willing cooperation from the village for US Forces.

ITEM:  The use of cartoons and caricatures tends to reduce the effectiveness of propaganda.

DISCUSSION:  Based upon interviews with several HOI CHANH, it was found that (illegible) cartoons or caricatures for illustration in larger than life figures, animated helicopters, etc., tends to discredit the entire leaflet even though the message itself may be a valid one.

OBSERVATION:  When drawings are used for illustrations, they should conform as much as possible to true-to-life representation.  Whenever possible, photographs should be used to add credibility to the propaganda message.

ITEM:  Ground loudspeaker and leaflet ops have a greater degree of effectiveness than aerial ops.

DISCUSSION:  Indications are that ground loudspeakers and leaflet missions continued along Hwy #1 have a greater impact and produce more response than aerial loudspeaker and leaflet drops.  Although the area covered is considerably smaller, the message is more effective since it is more personalized.  Ground mounted ops are very effective for offering mine rewards or exploiting VC atrocities which occur near populated areas.

OBSERVATION:  A greater emphasis be placed on hand dissemination of printed material and vehicle mounted loudspeaker ops.

               NARRATIVE REPORT

1.     GENERAL:

     During the period starting 1 August 1967 and terminating 31 October 1967, this Battalion continued to support the 25th Infantry Division in all operations.  Multi-channel VHF systems continued to provide a major portion of the communications for the Division as increasing use was made of this means to interconnect Fire Support Bases and Battalion Patrol Bases.  The VRC-12 series radio remains the initial means of communications and the primary back-up for existing VHF systems.  During the period, a detailed survey of FM radio operations, requirements and configurations was conducted.  The more significant lessons learned during this period are contained in this report.  This report supplements the 1 May to 31 July 1967 report.  Lessons learned reflected in that report are not repeated in this one.

2.     SECURE FM:

     One of the findings made during the period will, I believe, have serious impact upon the planned program for the application of secure equipment to all FM nets.   We have found that any interference on the frequency assigned for secure use will interrupt and make unreadable transmissions in process in the secure mode.  For completely reliable secure transmission, free from continuous interruption, “totally discreet” frequencies are required.  Based upon our experience, such a frequency is extremely rare.  Therefore, reliable land responsive secure transmission over multiple nets does not appear to be feasible utilizing the KY-8 or similar device.  Development of a security device which is not sensitive to interference is necessary in view of the requirement to “share” frequencies.  


     Present TOE authorizations for FM radio equipment in the Headquarters and Headquarters Companies of the Infantry Division, Brigades and Battalions are inadequate to completely meet the communications requirement in the counter-insurgency effort in Vietnam.  During combat operations in forward locations, the Battalions habitually establish small command posts from which to maintain tactical control of their maneuver elements.  The FM radio equipment authorized by the TOR is adequate to meet this requirement.  However, a Tactical Operations Center (TOC) must also be maintained at the Battalion's base camp for command, control and coordination purposes.  Photograph 1 at Tab A shows the typical base camp TOCL  FM radios in use by an infantry Battalion engaged in field operations.  The same situation exists at Brigade Headquarters, since a Tactical Operations Center must be maintained at Base Camp while the Brigade operates a forward CP.  Photographs 2 thru 5 at Tab A show the FM radio configurations in use in one Brigade Base Camp Tactical Operations Center.  In the forward area, a like FM radio requirement exists.

     The same general situation is also found in the Division Tactical Operations Center (DTOC).  Photographs 6 and 7 at Tab A show 2 radio configurations installed in the DTOC.  These radios must be maintained at all times for command and control purposes and for coordination between the staff planners at base camp.  They must be duplicated at the tactical command post in a forward area.

     Another serious drain on tactical FM communications is the requirement for radios for base camp defense nets.  A significant number of RT-524's and AN/PRC-62's are “tied down” at base camp observation towers, listening posts, firing bunkers and command posts.  Units man the base camp defenses as an “additional duty” while continuing their basic field missions.  The radios employed for base camp defense are diverted from TOE assets that should be with the unit in support of their basic field mission.

     To help meet this greatly expanded combat requirement for FM radio communications in tactical operation centers, radios have been taken from lower priority staff officers.  This action leaves many personnel and sections without the communication equipment authorized to accomplish their assigned missions in a timely and efficient manner.

4.     Power Source for FM Radios:

     Quite often FM radio equipment must be operated for extended periods of time in a ground mount configuration, removed from the vehicles in which they are normally installed.  The TOE configurations depicted in the previous paragraph exemplify this requirement.  This requires a 24 volt DC source other than that provided by the vehicle.  Usually, two 12 volt vehicle batteries wired in series are utilized for powering the equipment with a charger or rectifier to maintain the batteries in a charged state.  These rectifiers are often hard to come by.

     In the 125th Signal Battalion, another method has been utilized with excellent results to maintain the charge on the batteries.  Certain AC generator sets, such as the 10 KW air-cooled generator SF-10 (MD) and 10 KW, water cooled FERRO I, are equipped with battery charging receptacles.  The purpose of the receptacle is to permit a DC generator to be utilized to charge the batteries of the AC generator sets.  Through the use of an adapter, a power cable can be connected to this receptacle (See Tab B) in order to use it as a source of DC for operating FM radios requiring 24 volts DC.  This system is a highly reliable, efficient and effective method of providing power for the operations of FM radio equipment.

5.     Masts for FM Radio Antennae:

     To increase the effective range of the VRC-12 series of radios, this unit has utilized telephone poles at base camp for antenna masts.  Telephone poles ranging in height from l48 to 90 feet have been used depending upon the required range and terrain.  The added height over the standard 12.5 meter RC-292 antenna has greatly extended the range of base camp radio stations.

     In areas where there is a requirement for several antennae, such as Brigade and Division Tactical Operations Centers, a “bonnet” constructed from an ammunition canister and engineer stakes (see Tab C, picture 1) may be mounted atop the telephone pole (Tab C, picture 2).  This “bonnet” will mount as many as four RC-292 antennae.  Tests have shown negligible interference among the antennae so mounted as long as a frequency separation of at least 3 MC, and preferably 5 MC, is maintained.

     This field expedient also results in a significant savings in space in the CP in that the extensive area required to erect multiple antenna masts with associated buy lines is eliminated.

6.     Antenna Masts for AN/MRC - 69's:

     Erection of standard 45' antenna masts in areas with heavy tree growth or swamps is a problem.  
The problem occurs when the antenna sections must be assembled on the ground before being “gin-poled” to a vertical position.  Lowering the mast to trouble-shoot the antenna, or to change dipoles necessitated by a frequency change is awkward and time consuming.

     The AB-557 antenna mast (depicted at Tab D) designed for use with the AN/GRC-50 radio, has been tested as a replacement for the standard TRC-24 mast by the 125th Signal Battalion in the Vietnam environment under combat conditions.  Tests have proved tha the AB-577 is ideal to meet our requirements here.  We have learned the AN/TRC-24 antenna reflector, AT-214, can be affixed to the AB-577 (shown in Tab D) without modification.  Since the AB-577 is required for specialized conditions only, it is not felt that each AN/MRC-69 need be so equipped.  A quantity of ten (10) of these antennae would be sufficient, as an example, for this unit operating in the current terrain.  The AB-577's appear to be in short supply however, and we have been unable to obtain the quantity we feel desirable.

7.   Secure VC Retransmission Station:

As utilization of the new VRC-12 series of radios with the secure voice equipment (TSEC/KY-8)
expanded, the requirement for a secure retransmission capability became evident.  There is presently no standard equipment configuration available to meet this secure retransmission requirement.  As an interim measure, the 125th Signal Battalion has devised a manual retransmission station which will allow retransmission of secure information utilizing the KY-8 and  -RT-524.                    (P3)

     First, two secure radio stations are established, one on each of the selected operating frequencies.  The two radios are then inter-connected, utilizing a modified control radio set, C-2299/VRC.  At this point, a locally fabricated control box is connected into the Radio Control Set.  Tab E, picture 1, shows the secure retransmission station ready for operation.

     The heart of the retransmission station is a two switch control box (see Tab E, picture 2).  Positioning of one switch allows either automatic clear retransmission, separate utilization of each radio, or manual operated secure retransmission.  When the first switch is set in the secure retransmission position, the operator at the secure retransmission station monitors the transmission and operates switch number 2 to connect one secure radio to the other when he hears “over” at the end of each transmission.  Basically we utilize radio wire integration (RWI) operating techniques in the operation of the secure retransmission station.

     Although the system described requires the presence of an operator when in use, it provides a vital link in the communication network for the Division and allows secure retransmission of combat essential information over extended distances when required.

8.     Multi-channel VHF Diagram - 25th Div Monsoon Campaign as of 22 October 1967:

Multi-channel VHF links remain as the backbone of the Division communication system.  Wide
Dispersion of Division elements during the period resulted in added emphasis being placed on the ability to support these elements with artillery fire.  A marked increase in the number of Fire Support Bases (FSB) requiring Signal Battalion VHF support was experienced.  A diagram depicting typical multi-channel VHF network during the period is attached at Tab F.

9.     Drying of Photographic Film:

     Difficulties have been encountered in providing adequate dust free facilities for the drying of photographic film.  Even in areas where limited air-conditioning is available, dust still remains a major hazard to the production of high quality film negatives.  Since standard air-tight film drying cabinets are not available, this Battalion has found a partial solution to this situation.  Tab G, picture 1, shows a rough film drying cabinet approximately 2'x 3'x 2' which has been fabricated from plywood.  Inside the cabinet, two light sockets are mounted.  Each contains a 150 watt light-bulb.  The end result is shortened drying time for the film with minimum exposure to dust.
     Based on the success of this initial endeavor, the 125th Signal Battalion is in the process of constructing a larger, improved drying cabinet utilizing the same principle.  A sketch of the new cabinet is attached at Tab G (picture 2).

10.     Reduction of MOISTURE and DAMPNESS in Cameras:

     During the rainy season in Vietnam, a constant problem is encountered in maintaining photographic equipment, especially cameras, in a dry, moisture free atmosphere.  Moisture in the camera creates a maintenance difficulty along with general deterioration of the metal land fabric parts of the camera.  Additionally, the rapid growth of mildew and fungus which results from the warm, moist climate in South Vietnam contributes greatly to camera operation problems.

     The 125th Signal Battalion has combated this problem by building into a shelf system a sealed cabinet with light bulbs similar to a film drying cabinet.  A picture of this facility is shown at Tab I.  Storage of cameras and associated equipment in this cabinet keeps the moisture level down, thus retarding the growth of fungus and virtually eliminating mildew and moisture damages.

8.     (C)     Intelligence:

          a.     Intelligence collection and studies, prior to the start of Operation YELLOWSTONE, indicated that War Zone “C” had long been a major VC/NVA base area for elements of COSVN HQ and subordinate units consisting of:  69th Artillery Regt, 1st Guard Bn, 680th Training Regt, 7th NVA Div, 82nd Rear Services Group and possible elements of the 9th NVA Div.  The total strength of these units was estimated between 10,000 and 14,000; however, in late November 1967, the 9th VC Div moved into Northwestern Binh Long Province and other units were dispersed down to battalion-size units throughout War Zone “C”.  Initially, their pattern of activity was to defend supply areas and to fight delay actions, allowing COSVN Hq to move north across the Cambodian Border.  Once this was accomplished, enemy forces conducted counter sweep operations and attacks on friendly base camps.

          b.     War Zone “C” is characterized by extremely heavy jungle vegetation and occasional open areas.  The hydrography of the area is restricted to two small streams which had little effect on friendly or enemy movement.  The terrain was heavily dotted with trenches and fortifications.  The largest concentrations appeared to be in headquarters and cache areas just south of the Cambodian Border.

          c.     In the first week of the Operation, friendly units met with little enemy resistance.  Most of the contact was limited to indirect fire harassment and probing actions.  Intelligence indicated that COSVN HQ and its security guard units were located due north of KATUM, probably moving across the border.  Other unit dispositions and locations were unknown; however, it was suspected that elements of the NVA 7th Div were dispersed to the south and east of KATUM.  There were no signs of a mass exodus of War Zone “C” upon the arrival of US troops.

          d.     Significant contacts during the operation were generally with company or smaller sized units defending base camps.  There were a few instances of enemy units attacking ARVN or FWF during sweeps, but the majority of activity involved contact with VC/NVA units in heavily fortified base camps or forward defensive positions.  Enemy tactics were to make the operation as costly as possible while committing a minimum of troops.  He made extensive use of indirect fire, employing 60mm, 82mm, and 120mm mortars and 122mm rockets.  These attacks were generally used for harassing purposes, attempting to inflict casualties and destroy supplies rather than to support ground attacks.  However, the enemy did no two occasions demonstrate a capability to conduct a multi-battalion attack on friendly FSBs.

          e.     The enemy employed AT mines on Route 4, but AP mines and booby traps were conspicuous by their absence.

          f.     Significant enemy losses:

               (1)     08 and 09 Dec 67:  4-9 Inf Bn vic XT 299 938 located three caches containing 350 tons of unpolished rice.  The rice was later evacuated.  

               (2)     200140-200500 Dec 67.  The 4-9 Inf Bn FSB BEAUREGUARD (XT380 855) was attacked by estimated 1-2 NVA battalions from the 141st NVA Regt.  Results:  6 US KIA, 12 US WIA; 40 VC KIA (BC), 33 KIA (POSS), 18 small arms, 9 crew-served weapons, and 1 PRC-10 radio captured.

               (3)     041030 Jan 68.  B Co 2-14 Inf located and destroyed 40 tons of polished rice vic XT 358 858.

               (4)     171428-171700 Jan 68.  2-14 Inf engaged an estimated 2 VC companies vic XT 348 908.  Results:  2 US KIA, 13 US WIA; 13 VC KIA (BC), 1 small arm and 5 heavy weapons captured.

               (5)     251415-251620 Jan 68.  2-14 Inf engaged an estimated VC company vic XT 248 952.  Results:  1 US KIA, 16 US WIA; 20 VC KIA (BC).

               (6)     031513 Feb 68.  A Co 4-9 Inf ambushed a VC squad vic XT 362 870 resulting in 7 VC KIA (BC), 2 pounds of documents and 1 machine gun.

               (7)     070015 Feb 68.  1st Brigade CRIP ambushed an estimated VC company, vic XT 186 504.  Results:  1 US WIA, 2 PF WIA; 26 VC KIA (BC).

               (8)     161245-170900 Feb 68.  2-14 Inf engaged one VC battalion vic XT 242 483 entrenched in Tay Ninh City.  Results:  4 US KIA, 25 US WIA; 81 VC KIA (BC).

               (9)     19 Feb. 2-14 engaged an estimated VC company with all organic weapons and supporting fires vic XT 0754.  Results:  3 US WIA; 66 VC KIA (BC), 2 VC POW, 81 rounds 107mm rockets, and 114 rounds 82mm mortar.

          g.     The heavy jungle in War Zone “C” made movement slow and tiring.  Streams were for the most part an insignificant factor in effecting movement.  The ground was hard, but the jungle restricted movement of tracked vehicles to the road.

          h.     Observation and fields of fire were extremely limited by the dense vegetation.  The VC overcame this by making extensive use of observers in trees.  In this manner, the VC were able to accurately adjust mortar fires on the FSBs.

          i.     The overall evaluation of the intelligence information gained from local and attached sources was considered to be C-3 (sometimes reliable, possibly true).  In War Zone “C” there was a lack of local agents.  Most intelligence was from the combat troops and aerial detection devices.  Operational security of Operation YELLOWSTONE was considered fair.

               (3)     Route 247 (XT 101 758 to XT 272 772)

10.     (C)     Concept of the operation:  The 1st Brigade conducted combat operations with the 4-9 Inf, 2-14 Inf, and the TF 2-34 Armor constituting the major force.  Combat Operations were designed to support the engineer effort at KATUM and PREK KLOK, THEIN NGON, and secure logistical convoys to KATUM, and to search out and destroy VC/NVA forces and bases.  This operation was conducted in three phases.

          a.     Phase I.  (D-Day to D+10)  The 4-9 Inf, 2-14 Inf, 7-11 Artillery and the 588th Engineer battalion were airlifted into the CIDG secured LZ at KATUM, and conducted combat assault vic KATUM with the 4-9 Inf and 2-14 Inf.  TF 2-34 Armor secured movement of the heavy engineer equipment to KATUM, artillery to PREX KLOK, and logistical convoys on Route 4 from MUI BA DAN to KATUM, and began improving the KATUM airstrip to receive C-130 aircraft.

          b.     Phase II.  (D+10 to D+60)  The 1st Brigade conducted methodical search and destroy operations within the TAOR, opened Route 4 for overland resupply to PREK KLOK and KATUM.

          c.     Phase III.  (After D+60) YELLOWSTONE forces began phasing down.  2-14 Inf and HHC 1st Brigade returned to TAY NINH BASE CAMP 8 Feb 68 with the remaining elements closing TAY NINH 23 Feb 68.

11.     (C)     Execution:  1st Brigade received the 25th Infantry Division OPLAN 18-67 (Operation YELLOWSTONE) dated 281900H Nov 67.  The 1st Brigade prepared and implemented OPORD 12-67 (Operation YELLOWSTONE) dated 031200H Dec 67.  In executing D-Day of Operation YELLOWSTONE each battalion of the Brigade Task Force prepared their OPORD.  The 2-14 Inf and the 4-9 Inf conducted a combat assault into LZ's in the vicinity of KATUM, securing objectives designed to provide security to the Task Force elements to be quartered at KATUM.  The 588th Engr Bn from D-20 to D-1 cleared and opened roads required to support Operation YELLOWSTONE, and on D-Day convoyed to KATUM.  On D-Day, the 7-11 Artillery Bn was airlifted from TAY NINH to KATUM (FSB CUSTER).  TF 2-34 Armor from D-2 to D-1 occupied FSB BLISS (XT 287 642) and FSB HILL (XT 278680) while on D-Day the TF 2-34 Armor attacked north to establish a FSB at PREK KLOK (XT 288 815).

          b.     Significant contact:

               (1)     11 Dec 67:  4-9 Inf in an ambush patrol vic XT 275 960 engaged 2 VC with small arms at 0135H.  At 0218H, this AP received 50 rounds of 60mm mortar resulting in 1 KIA and 8 WIA.  The mortar fire lasted 21 minutes.  The AP requested a LFT, counter-mortar ship, and a Spooky.  Artillery fire was provided from FSB CUSTER (XT 333 903).  At 0313H, mortar fire began again with 10 rounds of 60mm from vic XT 268 975.  At 0316H, 14 rounds of 60mm and 1 RPG were received from vic XT 265 966.  Losses:  2 KIA and 22 WIA.  VC losses unknown.  NOTE:  By engaging the 2 VC with unknown results, the 4-9 compromised their position but did not relocate.

               (2)     120845 Dec 67:  While the 1-49 ARVN Inf was combat assaulting to an LZ vic XT 378 858, one of the UHIHs carrying troops was shot down vic XT 334 915.  The LZ was initially cold at 0836H but as the third lift to 1-49 Inf landed on the LZ at 0901H, they received 60mm mortar fire, indicating the LZ was hot.  The mortar was spotted at XT 390 857 and was engaged with a gunship and artillery.  Mortar contact was broken at 0937H.  The LZ remained cold after 0937H.

               (3)     121130 Dec.  The CO HHC, 1st Brigade C&C ship received small arms fire from vic XT 343 913.  Artillery was fired into the area.  At 1130H also a CH-47 extracting an UH-1D from XT 342 913 from XT 342 913.  At 1304H, FAC received fire from XT 342 913 resulting in no hits.  At 1425H, B Company 2-14 Inf received small arms fire from XT 342 913, returning fire with artillery and organic weapons.  At 1508H, B Company 2-14 Inf received additional fire from XT 342 913, again returning fire with artillery.  At 1514H, FAC received BAR fire from XT 342 913 and again artillery fire was delivered into the area.  Losses:  no friendly; enemy unknown.  NOTE:  Artillery does not negate the necessity for the infantry to move through an area to clear the area of VC.

               (4)     140827 Dec 67:  A Company 2-14 Inf received SA and AW fire from vic XT 343 912 from an estimated 2 VC.  Contact was broken at 0829H with no casualties.  Contact was reestablished at 0844H, resulting in 1 KIA and 1 WIA.  Contact was broken at 0910H and reestablished at 1035H with A Co receiving SA and AW fire and rifle grenades resulting in 2 WIA.  Contact broken at 1038H and reestablished at 1056H from a bunker vic XT 343 913 with A Co receiving AW fire and RPG from an estimated 20 VC; 90mm fire was delivered point blank on the bunker and an airstrike delivered at XT 343 912.  The airstrike resulted in 2 US WIA from A Co and one WIA from C Co who had maneuvered into the area to assist A Company.  At 1540H, A Company continued to sweep to XT 338 909 while C Company swept to XT 342914 without contact.  Friendly losses:  2 KIA, 15 WIA; enemy losses:  2 VC (BC).

               (5)     140940 Dec:  C Company 4-9 Inf received SA fire and claymore from vic XT 245 941 with sporadic fire continuing until 0950H.  B Company moved in to block the trails vic XT 241 937.  Contact was maintained until about 1100H.  An airstrike was delivered at 1105H to XT 250 940.  B Company moved to the north flank as the contact was reestablished at 1115H.  Contact at 1120H was vic XT 245 944 with this contact broken at 1147H.  Friendly losses:  6 KIA, 18 WIA; enemy losses:  7 KIA (BC), 10 KIA (POSS), and 3 RPG-2 rounds.

               (12)     11 Feb 68.  KATUM Base Camp received 31 rounds of 82mm mortar.  Some of the rounds contained “gas” which incapacitated 10 individuals.  The casualties were reported to be nauseous and have headaches at 1002H.  By 1330H, all of these casualties had been returned to duty.

               (13)     150825 Feb 68:  A Company 588th Engr Bn and 1 plastoon of A Company 2-22 Inf (M) en route to THIEN NGON were ambushed by an estimated VC company at XT 089 790.  The VC fired AW and RPG, resulting in 10 KIA and 2 APC destroyed.  The contact was broken at 0850H with unknown VC losses.

               (14)     160115 Feb 68.  PHU KOUNG, XT 234 746, began receiving mortar and 122mm rocket fire and ground attack.  MACV requested and got ½ APC ARVN troop and 2 ARVN Inf companies to support MACV.  Action broke at 0245H as it began at BIEN KEO, XT 231 435.  At 0510H, the mortar fire began again at PHU KOUNG and BIEN KEO, but the ground attack had ceased.  At 0345H, as both contacts continued, PHU KOUNG reported VC had entered the MACV compound.  One VC POW, captured by MACV, stated that his unit was from NUI BA DEN and that the unit would continue the attack until after sunrise, then would return to NUI BA DEN.  Contact was broken at PHU KOUNG at 0530H but continued at BIEN KEO.  At 0545H, the VC CP was suspected to be located vic XT 245 485; and the TAY NINH Province Chief requested US forces to sweep the area XT 250 493 to XYT 250 495 to XT 270 493 to XT 270 470, giving clearance to fire any type ordnance the US forces required.  By 1200H, 2-14 Inf was sweeping the area vic XT 27 49 and XT 28 50.  The combined force at this time was 4 US companies and ARVN companies.  Contact was established at 1245H and continued Vic XT 241 485 at 1905H and B and C Companies 2-14 Inf moved to support A Company 2-22 Inf (M).  At 1959H, three airstrikes were delivered at St 244 486.  Sporadic contact and mortar fire continued to 170425 Feb.  At 170806 Feb, it was reported that the VC unit had withdrawn at 170300 Feb.  Contact was not reestablished.  Friendly losses:  4 KIA, 25 WIA; enemy losses:  81 KIA (BC).  The VC force was estimated at 1 battalion.

13.     (C)     Administrative Matters:

          a.     PX facilities were not available to the troops in the field on this operation.  A mobile PX was considered but deemed not acceptable in that this would automatically result in the discontinuance of sundry packs.  Any desired items not included in these packs could be purchased by designated unit individuals at Tay Ninh and sent out on resupply.  This is preferable to the certain inequities that would occur if a mobile PX was available at the forward base camp.

          b.     There was considerable difficulty in the rapid distribution of mail in the early and intermediate stages of the operation.  This was largely due to the irregular air service.  A regularly scheduled cargo plane eliminated this problem.

          c.     Difficulties were also experienced in getting replacements, returning R&R personnel, etc. from Cu Chi to Tay Ninh and Katum.  Again, this was largely due not only to irregular aerial service but also insufficient flights.  Getting soldiers back to their units was always slow.  The problem would have been at incalculable proportions if it were not for the frequent ground convoys.

          d.     Supply:  All classes of supply were drawn fron Tay Ninh LSA who operated a forward support area at Katum.  Supply convoys were operated daily and controlled by DISCOM Forward.  Water points were operated at Katum, Prek Kloc, and Bau CO by the 588th Engineers Bn.  At Fire Support Base Knox all potable water was supplied by a water point operated by the 65th Engineers.  Showers points at Katum were operated by Tay Ninh LSA and at Bau CO by 588th Engineers Bn.  The greatest problem area of supply was ice, which seemed to be in limited supply at all forward camps.

               (1)     Class I:

                    “A” RATIONS     251,439     meals
                    “C” RATIONS     183,375     meals
                    LRRP RATIONS     680     meals
                    SUNDRY PACKS     1,079     ea

               (2)     Class II and IV:  A total of 345 tons was used in support of the operation.

               (3)     Class III:

                    Mogas     46,490     gal
                    Diesel     73,800     gal
                    Lub oil OE-30     2,370     gal
                    Lub oil OE-10     1,159     gal
                    Lub oil OE-50     1,450     gal
                    Lub oil OE-90     325     gal

                    Aviation Gas     13,232     gal
                    JP-4          18,000     gal

               (4)     Class V:

                    Ctg, 5.56mm     41.3     tons
                    Ctg, 7.62mm     82.0     tons
                    Ctg, Cal .45     2.8         tons
                    Ctg, Cal .50     139.2     tons
                    Ctg, 40mm     16.9         tons
                    Ctg, 81mm     347.0     tons
                    Ctg, 90mm     808.4     tons
                    Ctg, 106mm     3.6        tons
                    Ctg, 60mm     210.0     tons
                    Ctg, 4.2” Mortar     279.5     tons
                    Hand Grenades     14.5     tons
                    Smoke Grenades     15.5     tons
                    Mine, claymore     5.7     tons
                    Miscel, (flares, demo, sig)     13.3     tons

          e.     Maintenance:  Maintenance teams from the battalions were with their respective units.  They were able to perform all 2nd echelon vehicular maintenance.  The 725th Maintenance Battalion provided some maintenance facilities.  No 3rd echelon maintenance was provided in the field.  Problem areas for the 2/34 Armor were:

               (1)     Procurement of tank engines

               (2)     Availability of repair parts for M73 machine gun

               (3)     Support maintenance for fire control instruments, artillery and small arms.

          f.     Treatment of casualties, evacuation, and hospitalization:  Dust Off support was provided by Cu Chi and Tay Ninh MEDEVAC units.  Battalion aid stations treated patients for minor ailments and “D” Co, 25th Medical Clearing Station located at Katum handled all cases beyond the capabilities of the battalion stations.

          g.     Transportation:  Transportation was provided by organic vehicles, CH-47, C-130, C-123, UHID.

          h.     Communications:  Communications were provided by brigade and battalion sections; this consisted of FM and RTT.  UHF was provided by 125th Signal Battalion.

          i.     Medical Evaluation:  Personal health was general good throughout the operation.  One significant problem area was that of rat control.  Control measures included:

               (1)     Proper police of area, especially the mess area.

               (2)     Use of anti-coagulant poison.

               (3)     Use of traps and snares.

               (4)     Dapafane Malaria Prophylaxis was used in addition to the Chloroquins-Primacuin tablets.  No malaria was reported during the operation.  Common complaints included colds, minor cuts and scratches and, at first, sunburn.  Skin irritations were a persistent problem with most resulting from the heat.  These were minimized by the daily use of showering facilities.

14.     (C)     Special Equipment and Techniques.  None reported.

15.     (C)     Commander's Analysis:

          a.     All engineer projects assigned to the 1st Brigade were completed (USSF/CIDG camps at KATUM and THEIN NGON and improving the airstrip at KATUM to receive C-130 aircraft and constructing an airstrip at THEIN NGON to receive C-123 aircraft).

          b.     The roads were secured, cleared, and improved to support the Brigade operations within War Zone “C” and the Brigade located and destroyed many VC/NVA bases and forces.  At about D+30, there was a substantial decrease in VC contact as the VC moved into the Saigon area for their TET offensive.

          c.     From 18 Jan 68 to 15 Feb 68, all contact with the VC was with very small units or scattered individuals.  During this time, minor mortar attacks were the only VC offensive actions.  Major contact was established on 15, 16, and 17 Feb 68 which suggested that some of the units which had moved to the Saigon area had returned.  On 19 Feb 68, the 2-14 Inf located a VC company area which was suspected to have conducted the mortar attacks on the TAY NINH Base Camp.

          d.     Action continued throughout Operation YELLOWSTONE with sporadic contact almost daily.

          e.     The use of airmobile assets enabled the Brigade to assault a large portion of its TAOR.  Without airmobile assets the Brigade was restricted to the immediate vicinity of its base camps.  When restricted to assault entirely by ground movement, the effectiveness was minimal since the VC units began to move around the US installations and effective ground range.

          f.     Eagle flights were conducted infrequently because of the requirement to support US forces with artillery and the difficulty in moving and securing arty at temporary FSB's based on the dense jungles and lack of CH-47's to accomplish timely movements.

7.     Supporting Forces

     A.     Artillery

     1.     During the period of Operation YELLOWSTONE, the 2/77 Arty was in direct support of the 3rd Bde and attached maneuver battalions.  From 10 Dec 1967 until 15 Dec 67, A/6/77 Arty was attached to 2/77 Arty and in DS role to 3rd Bde elements.  From 29 Dec 67 until 31 Jan 68, A/3/13 was attached and in a GSB role to 2/77 Arty.

     2.     Normal use of preplanned and on call fires were used extensively during the operation.  During Search and Destroy missions by maneuver battalions, effective use was made of blocking fires along routes of march.  One highly effective technique, particularly during the occupation of FSB BURT, was the employment of close-in H&I's.  These were fired in great volume at BURT and were believed instrumental in the suppression of VC mortar attacks.

     3.     During the battle of SUOI CUT (1-2 Jan 68), artillery played a highly significant role.  Direct fire was employed upon attacking VC forces in large volume.  During the battle, approximately 60 rounds of beehive ammunition were fired and were believed instrumental in stopping the VC human wave assaults.  During the attack, interdiction fires were fired on withdrawing enemy forces from FSB BEAUREGARD (vic XT381856).

C.     Army Aviation:

(1)     The brigade conducted numerous airmobile operations during Operation YELLOWSTONE by the 269th combat aviation battalion.  Working with the same helicopter companies is highly desirous as coordination is greatly simplified.  In addition, quick reaction insertions and extractions can be accomplished with minimum loss of time.

(2)     The brigade aviation section flew a total of 825 hours and 1734 sorties in support of the operation.  A total of 1626 passengers were transported during this period.

(3)     The largest single event during Operation YELLOWSTONE in which Army Aviation was involved was the battle of SOUI CUT on 1-2 January, 1968.  The Spartans from the 145th Combat Aviation Battalion arrived at 0330 hours with Class IV emergency resupply.  They were joined by the Little Bears of the 188th AHC.  Some of ammunition had been exhausted and others were critically low.  While the battle raged around them and while drawing intense hostile fire, on each approach, the slicks continued to bring in ammunition, without which Fire Support Base BURT could not have been successfully defended.

(4)     Fire Support Base BURT was located in the northeastern portion of War Zone C (XT500805).  The ground was dry and had been ground into a fine powder,  Due to the number of units occupying the area, air traffic was heavy and dust caused by the down wash of the rotors was a continuous problem.  This problem was partially alleviated by the establishment of two helipads, one for CH47 resupply aircraft and the other for command and control of OH23's and UH1's.  One pad would not suffice due to congestion and CH47 rotor wash.  These pads were covered with Peneprine using a 600 gallon spreader daily.  Air traffic control was achieved by utilizing pathfinders from the 25th Aviation Battalion.  A direct line link was established between the pathfinder and the artillery FDC to coordinate check fires for arriving and departing aircraft.  To avoid constant check fires, an air corridor was established through which all aircraft arrived and departed.  Depending on the tactical situation, this corridor was often changed to meet requirements.

(5)     Gunship support for the battle of SOUI CUT was provided by C Troop 3/17 Cavalry, 187th and 188th AHC's and Company B, 25th Aviation Battalion.  These aircraft were effectively employed to assist in blunting the two regiment attack.

8.     (C)     Intelligence:

     A.     Intelligence concerning the Brigade AO was obtained from 25th Inf Div S-2, and through Liaison with advisory teams.

     B.     The AO extended from War Zone “C” to the vicinity of Saigon.  Terrain varied from dense double canopy jungle to rice paddies and swampy lowland areas.

     C.     The following enemy initiated actions occurred:

     (1)     Sniper fire     41
     (2)     Mortar fire     57

     (3)     Mines          27

     (4)     Booby traps     10

     (5)     Engagements     60

     (6)     Fire against aircraft     14

     D.     The following major incidents occurred:

     (1)     131445H December 67:  B/3/22 Inf destroyed 6000 potato masher grenades and 9000 baseball grenades at XT429737.  These grenades were protected by Cosmoline and stored in 55 gallon drums, which were buried in the ground.

     (2)     012300H January 68:  FSB BURT (XT500805) received a ground attack from an estimated VC regiment.  The attack lasted from approximately 2300 to 0400, during which time the 3rd Brigade killed 355 VC, apprehended 500 PW's, and captured 75 AK-47's, 16 RPG-27's, 12 RPG-7's, 11 LMG's and 1 pistol.  US losses were 19 killed and 111 wounded.

     (3)     050902H January 68:  B/4/9 Inf encountered heavy resistance on a landing zone at XT5 3093.  In the ensuing engagement, 3rd Bde killed 65 VC (BC) and 200 VC (POSS), while losing 7 killed and 16 wounded.

     (4)     0914301H January 68:  B/3/22 discovered an arms cache at XT482792.  They evacuated and destroyed a total of 11,650 rds of 7.62mm ammunition, 14,000 blasting caps and 66 cases of demolition.

     (5)     300630H January 68:  The 3rd Brigade base camp at Camp Ranier (XT495473) received 8X107mm rockets; 107 (illegible) rockets were received again on 31 January.  This marked one of the first appearances of this Chinese Communist weapon in Vietnam.
