a. On 3 May 67 MGF 957 contacted a multi-battalion sized force vic XT951669. This unit was equipped with AK-47's, RPG-2 rocket launchers, 2-3 heavy MG's, unknown type mortars and recoilless rifies. There were many ethnic Chinese fighting with this unit. The ethnic Chinese were all wearing khaki uniforms. One other group of VC were wearing black uniforms with camouflage soft hats. Some VC were wearing blue uniforms. This unit was well trained. They employed both fire and maneuver (well executed) and human wave attacks were attempted after many of the MGF were casualties. This unit is believed to have been 271 VC Main Force Regiment AKAQ761-subordinate to the 9th VC Division. This is based on reports placing 271 MF Regt in the immediate vic, and on a report that the 271 employs many ethnic Chinese mercenaries. On 11 May vic YT039408 recon mission 8 observed a total of 200-250 VC moving south from 0355H to 0515H. The VC were using flashlights and traveling in 4 different groups (approx company size). At 0734H the SIGMA FAC located 50-75 of the VC in an open area vic YT023378 and at 0802H TAC air was put in on the VC. Reaction by 2 platoons of 1st Company resulted in capturing 2 PW's and numerous documents that identified the units as 2d Company, 2d Bn, 273 VC Regt, AKAQ763, subordinate to VC 9th Div. Also, C-23, Medical Detachment, subordinate to 273 VC regt. Uniforms were mixed cloths of black, blue, and green. On 17 May MGF 957 located a large concentration of VC vic YT143578 (center of mass). There were many well used trails running coast-west throughout the area. Commo wire was run along some of the trails. All VC in the area were equipped with

Page 213

new CHICOM series of weapons (1956). Uniforms were well cared for and troops appeared well groomed and healthy. This is believed to have been part of 9th Div HQ Security. SPAR reports indicated that 9th VC Div is located northeast of center of mass coordinates given.

b. The 9th VC div is apparently massing its subordinate regiments in War Zone "D." This could be a temporary move for attacks on targets near War Zone "D" but more probably the 9th VC Div has moved into War Zone "D" on a permanent basis. Presently, the only two 9th Div Regiments believed to be in War Zone "D" are the 271 and 273 VC Regts. Both located and identified by Operation Black jack 33.
