on KCP/KPLA request. Others remained in Kampuchea with military region
staffs along the Kampuchea/Vietnam border, where PAVN/SVNLA units
continued to operate. ,_
After the KCP/KPLA takeover of Phnom Penh on 17 April 1975 and the
establishment of Pol Pot's Democratic Republic of Kampuchea (DKR) with
Chinese backing, relations between the KCP and Hanoi continued to
deteriorate. The last vestiges of Vietnamese influence over the KCP and its
KPLA disappeared as Vietnamese-trained Khmers were systematically
removed from their positions. New developments occurred after Pol Pot's
KPLA began ‘launching cross-border attacks into Vietnam. The PAVN
services, including CDV field elements, supported PAVN retaliatory attacks
into Kampuchea. This eventually led Hanoi to make the decision to topple the
Pol Pot government and to remove it from power with a Khmer Government
which Hanoi could control. Hanoi proceeded to create the antilPol- Pot
Kampuchean National Union for National Salvation (KNUS) front, and
developed its Kampuchean People's Revolutionary Army (KPRA). The PAVN
services, including the CDV, were undoubtedly involved in the training and
development of the small KPRA enemy proselytizing service, which now
operates as an extension of the CDV in Kampuchea. On 25 December 1978,
PAVN launched its major offensive into Kampuchea which seized Phnom
Penh on 7 January 1979 and which installed its KNUNS front as the
Kampuchean People's Republic (KPR) under Premier Heng Samrinn
As of July 1979, PAVN has an estimated 225,000 personnel committed to
action in Kampuchea against the KCP/KPLA. About 3,300 CDV personnel
accompanied PAVN forces into Kampuchea. Each infantry division political
staff has a" 50-man enemy proselytizing section, including a 25-man detention
facility for POWs. Each regimental political staff has a 10-man enemy
proselytizing subsection, and each. battalion has a three-man enemy
proselytizing cell. -
