Region 5 Enemy Military Proselytizing Section (EMPS) operations against
US military personnel emphasized the recruitment of Vietnamese
interpreter/ translators, as well as the preparation and distribution of English-
language psychological warfare leaflets and pamphlets to subordinate
provincial-level EMPS. The Region 5 EMPS organized intelligence teams to
collect information on US/ Allied sweep operations; promoted antiwar
sentiments in US combat units; and supervised the administration, detention,
indoctrination, and interrogation of captured US / Allied and ARVN personnel.

ARVN, Australian, Filipino, ROK, Thai, and US military personnel with the
objective of creating and exploiting friction between them in order to reduce
their combat effectiveness and to induce increased desertions and acts of
mutiny against participation in combat actions. Allied forces of the US were
branded‘ in EMPS propaganda as hired US mercenary forces who had no
national interest in fighting a war in Vietnam.
Two subordinate components of the Region 5 EMPS were involved in
operations against the American target. They were the Region 5 EMPS
Propaganda Subsection, and the Interrogation and Detention Camp Subsec-
tion. Its subordinate Quang Da Special Region (QDSR) EMPS was similarly
organized against the American target. Eight other subordinate provincial
