d. (C) Intallitsic

(1) Discussion:

(a) General: bemy activity against US Forces in Long An Province duringthis reporting period continued te remain at a fairly moderate level. TheSummer Campaign, which is now moving into Phase Two, is the Only high point tobe recorded during this reporting period. Phase Two was to start between 25April 70 and early May. Tactics that were to be employed in this offaisive phasewere attacks by fire, Sapper attacks and large scale ground attacks. The 3dphase of the offensive is scheduled for early June 70. Generally, enemy activityis usually scattered, with smell AhVN and IF, IV, OP's as the enemy's main targetfor attacks. The enemy continued to place a strong emphasis on Sapper tacticsas one of their key weapons against isolated I7, PY compounds. Because of lowstrengths and a failure of the Rear Service to supply equipment in adequateamounts and quantities, Main Force Units and the lot WA Rlet have been assigneda mission of avoiding contact and couuorlmg the GO1 Pacification program inLong An Province. Local Force Companies have been used to guide Main Force Unitsand replacements and act as security elements for meetings of Villogse and Districtcadre.

(b) February: Activity during the mouth of February was limited to scat-tered contacts. On 23 Feb 70, an increase of eswe movement occurred throughoutthe province. US operations on the night of 20 Fob resulted in 23 enemy KIA.There was a sharp decrease in enemy moment detect:ed the fellowing night.

(d) April: fnemy activity during the munth of April was somewhat of anincrease. The reason for this was possibly due to the initial start of PhaseI of the Summier Campaign. During this month, the enemy only suffered a lossof 115 men. This is the lowest number of enemy KIA during the reporting period.Also during this month there were six attacks by fire on US installation3.

During the month, the K5 NVA Battalion was once again contacted numerou,times resulting in a 0ose of at least 26 NVA to the unit. The largest contxctcame I April 1970, when the 60 X? Co engaged an estimated squad of enemy e-,sulting in six enemy KIA and one NW.

(2) Enemy Order OF Battle.

(s) Recapitulation- During the period, VC/NVA combat effectiveness contlinueIon a low scale. The enemy a rear service is continuing to operate under s.vfr.handicaps because of low strengths in many units. The lst Ind NVA legt remainsthe dominant unit in the AO but haa been suffering ever increasing casualties,NW's and Roi Chanhs. All Main Force elements in Long An Province are trying toavoid contact and are hiding in an effort to build up lost strength. LocalForce units are at very low strengths; in fact, one of these units, the C2 TanTru LFC was completely dropped from O listings because of lack of contact andidentification for a period of approximately one year.

1. The let Ind NVA Regt has been extremely active in Long An Province inthe past three months and has sustained many casualties. Of special interstis the K5 Battalion which has had approximately a 40% loss in strength due toAllied activity and desertion.

2. The 6th XF Battalion was last identified from documents captured in acontact on 12 March 1970 vie XS683830, This unit was alIo contacted on 5 March1970 vie X9683814 and one PW from 3d squad, 3d platoon, 6th Wf Battalion wascaptured. Re stated that the Battalion has a strength of 174 sen. The OR MYBattalion became fairly active during the period I Feb * 30 April 1970. CnY-',c%was made with this unit on 10 Feb resulting in four enemy KIA. On 12 Feb document.,were captured at vie XS604793 identifying the 308th. On 16 April 1970, vic XS-666782, two enemy KIA were identified as members of the 308th W Battalion, Th,,211 Wf Battalion has been very active in the last three months. There have bi.nnumerous captured documents, Hol Chanhs, and PW's attesting to the units op-erations in Long An Province, On 15 March 1970, vie X8717649, the PoliticalOfficer of the 211 Wf Battalion was captured. The 211 remained dispersed in aneffort to coneerve strength. The 265 Battalion has continued to operate at auextremely low strength level. According to documents captured 14 March 1970.there is an indication that the 265 Battalion possibly has be" reduced to acompany size unit. Last contact was made on 18 March 1970 when bttional Policeapprehended one detainee who was a deputy hamlet chief and a member of the 265If Battalion. The 520 Hf Battalion had been all but wiped out at the end of thelast reporting period. The strength of this unit was 50 VC/WVA at the end of thelast reporting period as compared to 175 at the beginning. At present the stren-gth of the 520 MY Battalion is eight VC/NVA.

(3) Discussion of Enemy Techniques and Tactics

(a) During the reporting period, enemy initiated activity remained at alow level, with March as the lowest month.

(b) Due to the increased GYN and Allied operations end the success of th•Pacification Program, the enemy is gradually losing the security of his lines ,'fcommunication and his once numerous hiding places, In accordance with COSV Rles-olution #9, an all-out military effort has been discontinued, and the eneay hagfragmented the lot NVA Regiment and his W Battalions by operating in dispersedfive to seven man squads. The purpose of this is to conserve both manpower ande*utpment, and to allow these elements to establish control of the population intheir assigned areas by concentrating at the lowest level. Recent captured dec-uments point toward increased emphasis on guerilla operations using small scalesapper tactics to overrun isolated GVY outposts and lightly defended hamlets,

(5) Intelligence Sources and Assets

(1) Significant Activities and New Techniques in the Area of Counterintellf'enc*.

1, The Counterintelligence Section (CIS), in keeping with its basic mission,employed eight (8) coded sources, five casual informants and six tiger scouts.During the reporting period, CIS msnpower was increased by the assignment ao fouradditional special agents. This increase in personnel made possible a vew programof assigning specLal agent personnel directly to the three maneuver battalionsof the Brigade. These special agents have established field offices with therespective battalions which now operate in conjunction with the central fieldoffice located at 493d MI Detachment Headquarters. Bach field office controlsits own informant net. The presence of these offices with each battalion hasgreatly reduced the time period between acquisition of ir.formetton by CIS anddisseminatton of information to reaction elements. Working closely with thebattalion S2, the CIS personnel are able to provide tuformation on a very tivelvbasis. To further the dissemination of information, all reports produced bybattalion field offices are sent by secure electronic means to the 82, 3d kLipd.This procedure allows the Brigade Comeader to be fully informed of intellisevicdita on a timely basis, so that the fullest co-ordination of response can beobtained, Because of the location of the field offices with the battalion 82's,:ocal agents help in solving problems of base camp security and the monitoringof the activities of indtgenous persomel in the base caup areas.

during the reporting period and has enjoyed increasing success with thiAp,.gr-am, The tiger scout, working exclusively under CIS direction, leadsc.ombat unit against intelligence targets. CIS has had continued successin the utilisation of codqd sources and Special Agent personnel to assisttht comander in the C&C helicopter in pinpointing intelligence targetsduring strikes. This technique precludes compromise of either the sourceor the Special Agent, and neither are in the area of conflict. Cooperationwith Field Station 34 of the 525th MI Group in Long An Province has providedvluable verifications of CIS reports and, on occasion, supplemented in-formation. Liaison with Province Security Committee advisors to the SpecialPolice, Provincial Reconnaissance Unit and Chiou Hoi programs has provided CISwith other extremely valuable information. CIS is also now receiving intel-ligence information from the Ministry of State Security which has given itvaluable leads, especially in regard to attempts by Comrunist intelligenceunits to penetrate US bases of the 3d Brigade. CIS has utilized Combined in-telligence Center Vietnam facilities in Saigon to develop a broader data basefor CI operations and information pertinent to the 3d Brigade TAOI. CLbcontinues to work closely with the 14th ARVN MID in a mutual exchange of in-formation and has just recently begun to work with representatives of theAustralian FVKAF operaring in an area adjoining 3d Brigade TAOD in an exchangeoi information germane to the mutual operations.

(b) The Prisoner Interrogation Section-

During the reporting period, the IN Section processed a total of 116d-tainees. Of this total, 24 were classified Innocent Civilians, 17 werekiassified Civil Defendant, five CD/VCI, 32 were classified PW's and 20 werelassified Hot Chanhs. In additln. the ,.,'ton processed 123 batches of capturel

(b) During the dry season infantry units, both mechanized end gr,.nd, wt:e.afforded hard ground on which to conduct operations. Additionally, airmobileoperations were never affected by adverse weather conditions. The dry terrainalso permitted longer operations without being plagued by imnersion foot andother fungus infections.

(c) The enemy was also provided with this increase in ground foot move-ment, however, the removal of the rice crop decreased the concealment availableco the enemy for his night movement. While on the other hand, the lower watercable gave him access to spny areas which previously had been too swampy tofortify.

(8) Enemy Capabilities, Vulnerabilities and Possible Courses of Action:

(a) The enemy has the capability to:

1. Conduct attacks on Province and District seats, other major cities,and military installations.

2, Conduct brief attacks by fire, hide his equipment, and withdraw fromthe area prior to employment of counter-mortar techniques.

3. Conduct attacks by fire and harassment on towns, villages, hamlets,outposts, and other installations.

4. Conduct sniper and terrorist attacks on kay bridges, roads, RD pro-jects and population areas.

.. Defend bese areas and positions with local security forces and reinforce

within a four kilometer area.

j. Disperse major units into platoon and squad etse elerents.

W. Withdraw and disperse easily.

3, Wep politial eand psychologtcal warfare on the pepulseas d hold eustrolof any area where there iosno friendly security at night.

(b) The anmy to vulnerable to :

5. Detection by friendly surveillance devices.

6 A breakdown in his infrastructure by aggressive allied actions.

7. A lack of combat effective troops and a low morale due to heavy casusltie3,and desertions,

(9) New Techniques:

(a) Continuing intelligence reports, Hoi Chanh information, and PW readoutsindicate that enemy movement during the hours of darkness along lines of cimun-Ications was being conducted by widely dispersed groups, Because of the Brigade'sintensified night ambushes and aggressive air assault techniques, Tat 1970 andCampaign "X" failed to materialize.

(b) Using a five man *skimmer" craft on the waterways enhanced interdictionand movement of men and material in Long An Province, RVN. The success of these"4,terborne" operations are attributed to the combined intelligence efforts ofArmy, Navy, and GVV forces participating in combined operations. increased useof small scale aerial photography in locating intelligence targets assisted the2d Battalion, 60th Infantry on 19 April 1970 in locating the lot Company, SR-3Comso Liaison resulting in 15 enamy KTA and disrupting a major infiltrationroute into eastern Long An f'xovince from the Ba Thu area, Each battalion S-2of the 3d Brigade has been staffed with a representative from IfP/, MI, 0 andan interpreter to facilitate processing of imeoiate tactical information, inter-rogation, establithment of local agent nets and exchanging informtion with theiriespective district counterparts.

(10) Techniques of radar Imploymeat:

(a) During the reporting period the Brigade Ground Surveillance Radar de-Lected 3880 sightings resulting in 545 artillery fire missions. The Brigadereacted to the targets of 10 ground surveillance radars, including the eight •CL-Sanic PPS-5 s, men Navy FPF-5. the P13-25 attached to the 2/4th Artillery, andthe PPS-25 orpeaLiag in the Pineapple Area. Due to recent detachoents in thebrigade our organic FPS-5 strengths has decreased from eight to six.

(b) Our radar effort has been concentrated in areas which the esemu usesfor Infiltzation and rasuppl;, t•i, at:- -fa wjr concern is the Plain of Reeds,.ond we have hWd nmeroaus radar sites in t:hat area. The loss of the attached TPS-ý,. -n 25 April 1970 1,as Irsatly decreased our coverage in the Plain of Reeds,

• tid required cC1c:.,ntrAt1ior of organic radars to componsace for its loss.

(c) The quick reaction to radar targets by a"•ll~ery is by far the mostdesirable method of engsgement, and even tho-igh survaillsnce of the target areacan not be conducted prior to dav'tght. the effectiveness of this technique bansuccessfully denied the qnery his major routes of commnication and supply.

Exceptfor the period I March to 16 Harch, when the enemy conducted nine attacks on Goutposts, there were few enemy initiated incidents. The comunistu continued toavoid decisive engagements with Brigade forces throughout the reporting period.

(3) The 3d Brigade has continued to keep pressure on the enemy through theuse of daily daylight Jitterbug Airmobile Operations and night CheckerboardAmbush Operations. These techniques have reduced the enemy0s ability to no"during daylight and made his susceptible at night. The number of enemy eliminateddecreased significantly in April as has the number of total contacts. The Brigadehad 129 contacts in February; 125 in March; and 81 in April.

(4) Combined operations continue to be the primary technique for upgradingGYM forces. These operations have rapidly increased effectiveness of GYM units.In April, for the first time, GTY forces accounted for more enemy killed the*Brigade forces.

(c) The MV0P campaign against th let NVA Regiment has been very successfulduring the reporting period through the use of five special tapes and three sp-ecial leaflets prepared by NVA ralliers and addressed to specific units of thelIt NVA Regiment. The taped broadcasts by NVA ralliera were found to be themost effective N8YOP appeal. Potential ralliers recognize the northern accentand feel confident that they could believe the message. Widespread dissatisfac-:ion is apparent in the lot NVA Regimont due to lack of medicine and equipment,lsolation from population, the necessity to constantly hide and fear of PUMA'sfirepower. All these fears have been exploited in operations against the 1st NVARegiment.

(d) The PS!OP section has intensified the iot Chanh interview program toobtain now thaws for exploitation. Reasons for rallying, methods to persuadecomrades to rally, ane exploitable conditions are the primary tiemes of thisinterrogation.

(1) During the reporting period the Long An Province 206-kilomterSa~ondary load Pro3rao received the major portion of engineer effort. 31.ements of the 20th Engineer Brigade, the AMYK 30th Engineer Group, US Navy Sea-bees, and the Brigade's organic 571st Engineer Company combined to raise theprogram's percentage completion from 13i to 53n. While slew delivery of contrac-tor-furnished laterite for the surface cap has delayed sen projects, rapid pi'o-gross has been made on bass course preparation. Two of the twentp-two roads com-prising the program are complete, and eight more need only the laterite cap.These eight are nam uwable during the dry season, and have contributed to pac-iftcation of the districts in which they are located. Tan Tru District reportsthe roads provide direct land access to areas which in the past could be reachedby military forces only after long foot marches or by air. In Ben Luc District,former residents who moved to Saigon years ago are now building home along thenewly opened roads.

(2) The enmay has acknowledged the success of the roads by increasing bonbytrapping and miding incidents designed to disrupt the program. To date, nocasualties or equipment damage have resulted. Many mines and booby traps havebeen pointed out by local villagers so that the roads would mat be destroyed.

(3) Tma organic 571st ngistneer Company has directed its resources toprojects requiring earthfill, as the rapidly approaching mnsomon season *illinundate barrow pits. Projects that can be completed 'during the rainy seasonhave been delayed to allow mextmm effort on these requiring earthfill. Combatsupport furnished by the engineers averaged one squad per say. Combat supportIs provided on a mission basis, as the live battalions have a limited iem seeofand demolitions capability. This capability enaMes the esginser eonpany toemploy their orgastic mine ep equipmsc in support of the umit's secondary roadprojects.

(4) 20th Rngimser Brigade units have completed all base construction insupport of tbe Brigade. They have bapn work on protective berm and minimaessential requirements for Tan An Airfield.

(3) Modified use of Airnobile Pile-On and exlnded initial insertionarea.

OBSERVATION, The VC/NYA build bunkers in patches of nippa along streamlines. These areas, which are very thickly covered and difficult to movethrough, provide emcellent areas for the VC/WIA to hide. Pile-On air-nobile operations were not completely successful in trapping enemy unitsin these areas,

E•VAUATION, In order to increase their security and defend againstU' airmobile operations, the enesF has spread his bunkers further apartand fragmented his units.

R!OOK=ATIONs That units of the 3d Brlade, 9th Infantry Divisionmodify the airmobile pile-on and expand the initial insertion area.Instead of attempting to immdiately seal the initial point of contactduring an airmobile Jitterbug operation, platoons should insert up to 1Jkilometers a&Wa from the initial point alona =Jor avenues of escape.Air caalry team should be used to cover the entire area and keep theen from wing. The platons then start a eeries of sweeping oper-ations wing toward the initial contact area. This tactic also allowsnrtillery to be employed while units are being inserted.
