13.   ADMINISTRATIVE MATTERS:

          a.   SUPPLY:  All requests of supply were available in sufficient quantities to meet operational demand.  Elements of the 1st Logistic Command provided supplies from their facilities at Tay Ninh.  25th Division Support Command provided a complete staff to meet all logistic requirements of th 2nd Bde. Task force.

          b.   MAINTENANCE:  Co C, 719th Maintenance Bd. Provided direct support during the operations.  No unusual problems were encountered.

          c.   SERVICES:   Laundry service provided by quartermaster facilities was inadequate.  Contractural services were provided, but were engaged far too late in the operation to be used.

          d.   TRANSPORTATION:   Courier from Cu Chi did not arrive daily in sufficient time to effect resupply of ice and mail to forward units.  Although scheduled to arrive at approximately 1300 hours daily, arrivals at times were later than 1700 and delivery of these items could not be made until the following day.

(a)  Troop haul requirements for infantry battalions were met by Support Command when requested.

(b)  With the exception of 2 convoys to the Brigade Forward Base on 13 and 14 Nov, all re-supply was accomplished by helicopter.  A total of 1,279 MF BG sorties and 26 CH47 sorties were flown in re-supplying.

(p21)
14.   Special Equipment and Techniques:

               (a)   Greater use of -----------was made to isolate cutting, mark clearance for arty and mortars, b-gl-r material, clearing areas for head-quarters and indirect fire wagons, and cutting used for surfacing roads.  For planning purposes, an area/maneuver battalion are required.

`15.   Commander's Analysis:

               (a)    Alternate LZ's must be prepared during the context of an airmobile assault.  This action provides a certain amount of deception and also insures adequate preparation of alternate LZ's if the primary LZ is found to be “hot”.    

               (b)   The judicious use of the air and arty during air-mobile combat assaults is the key to the rapid introduction of an infantry force in a combat picture.  This support must continue during the actual landings and extractions.  Sufficient time must be allocated for detailed coordination between all support services involved is: the inf. unit making the assault, tac air, stray air, and arty.

               (c)   As maneuver battalions are extended from forward supply bases to areas not serviced by roads, the resulting more ground time for helicopter re-supply quickly became unacceptable.  Planning must include positioning of supply bases on usable roads as for forward as possible.  

               (d)   Engineer support for elements operating in War Zone C is definitely essential.  Aerial readiness cannot give an estimate of all trafficability.  Many  streams require preparation (log-laying) before landings can be made.  -------------------teams and usable roads are a scarcity and precautions must be made for immediate replacement when ---become as far forward as possible.                   

 (p22)
               (e)   Mired or disabled vehicles present a major problem to Mech. movement.  It can be expected that there will be an increase in mining in the future operations in WAR ZONE C.  Planning must include provisions for security, repair, evacuations and destruction.

               (f)   Mechanized infantry can operate in most heavily wooded areas in WAR ZONE C to a limited degree.  Capabilities include provisions for rapid movement to secure forward bases, probing and reinforcement.

               (g)   All helicopter support must be controlled by the Task Force headquarters.  This system permits rapid change of priorities as the tactical situation develops.  Planning must include adequate areas in the rear for the brigade teams to include a landing area for helicopters.

               (h)   Planning for extended operations must include provisions for direct exchange of Class III items.

               (i)   Major component replacement for disabled mech. Vehicles is essential.  Planning must include provisions for immediate replacement and maintenance assistance from division forward support bases.
               (j)  It appears that the VC do not desire to engage large US Forces in War Zone C.

16.   Recommendations:

          Where possible, aviation support units should station liaison officers at the brigade trains and the brigade tactical command post.  These representatives greatly assist in the initial planning of an operation and provide the commander with detailed information concerning the mission as they are prepared.

ANNEX  A:     TERRAIN, TRAFFICABILITY, WEATHER


1.   General:   The terrain exploited by the 2nd Bde Task Force in WAR ZONE C was characterized by dense jungle and open marshlands.  Elevation ranged between 10 meters (XT2260) and 80 meters (XT1173), with the general average of 35-40 meters in the area of operations.  Relatively little land was cultivated;  the majority of agricultural efforts were small or individual garden plots.

2.   Roads and Trails:   Roads through the area reflect lack of cars and maintenance.  Portions of the major roads have been cratered by bombing and mines, and subsequent erosion has occurred.  Fallen trees in a few areas have blocked roadways making detours necessary.  The major road network from (XT284619) to KATUM (XT333898) to BO TUC (XT380857) were subjected to thorough air reconnaissance.  Road use of approximately 46 kilometers proved it to be adequate for tracked vehicles.  Major obstacles were found at (XT327893) where steep banks had to be leveled by demolitions to accommodate crossing.  Even after leveling had been accomplished, crossing was still reported to be difficult.  At (XT325886), craters and muddy conditions made trafficability extremely difficult.  

Trails and footpaths were observed throughout the entire area.  They appeared to occur at random, leading into dense jungles, (Appendix 1).  Due to the vegetation and the limits of advance, none of the trails could be explored completely.  LRRP reported that two trails (XT213879) were blocked at irregular intervals by cut trees and foliage.  The purpose of these blocks is unknown.  The LRRP also reported seeing several observation platforms built high in the trees at irregular intervals.  The patrol was unable to pinpoint the locations of these platforms.

3.   Bunkers and Fortifications:  In the area of operations, elements of the 2nd Bde Task Force encountered relatively few bunkers and trenches as compared with other areas: i.e., the HO BO WOODS, the BOI LOI WOODS, other known VC strongholds.  Bunkers which were manned and defended by fire were located at (XT224812) and (XT227813).  Other bunkers, as depicted in Appendix 1, were deserted, although most of them showed signs of recent repair.

4.   Base Camps:   There were nine base camp sites reported in the entire area of operations.  For the most part, the typical base camp found in WAR ZONE C consisted of several protective bunkers, a few small huts, a small cache of rice, garden plots, and evidence of recent use.  Base areas found during the operation are depicted in Appendix 1 and are listed below:

(XT303777)     Heavily booby trapped area with 20 tons of rice.
(XT243800)        Campsite for estimated 100 VC
(XT278828)     Campsite apparently used by 25 - 30 VC
(XT263757)     Campsite with 1500 lbs rice and a rice milling machine
(XT344919)     A series of cultivated garden plots and small huts
(XT383896)     Campsite with shower, latrine, and recently repaired bunkers.
(XT224810)     Five huts and extensive tunnel system:  defended briefly by VC    

 (p24)       

(XT329919)     Small base camp appeared to have been used by 30 - 50 VC
(XT349940)     Base camp large enough for 200 VC with fresh food in area.

5.   Cross Country Trafficability:  The axis of advance of the mechanized infantry battalions, the 1/5(M) and the 2/22(M), are depicted in Appendix 2.

Although there were mine incidents experienced, the greatest barriers are caused by      terrain, specifically jungle and lowland marshes.  Generally, movement cross country was slow with the daily average advance of 10 kilometers.   Land elements of the mechanized infantry normally required an average of one hour to penetrate 400-500 meters of dense jungle.  Difficulty for trail elements was encountered in low spots; at elevations of less than 35 meters, the swath cut by lead elements became too muddy and consequently impassable to trail elements, necessitating the cutting of new routes through the jungle.  

Marsh lands provided the greatest single obstacle to progress of tracked vehicles.  Soft mud predominant in open areas at elevations of 35 meters or less continually bogged down vehicles.

6.   Land Zones:  Areas suitable for helicopter landing zones are depicted in Appendix 3.

7.   Weather:  Weather facilities were available to the 2nd Bde during the period 18-23 Nov.  During this period, the following data were compiled:

     Average maximum temperature          89
     Absolute maximum temperature          92
     Average minimum temperature          74          
     Absolute minimum temperature          70
     Total precipitation                    .32  inches
     Maximum precipitation               .32  inches

Except for occasional  early morning fog and evening showers, weather did not materially affect air or ground operations.
