History of 4th PSYOP GP USARV

The 4th Psychological Operations Group (4th PSYOP GP), assigned to the United States Army Vietnam (USARV), was activated during the Vietnam War to conduct psychological operations in support of U.S. and allied military objectives. Established in 1967, the group specialized in disseminating propaganda, leaflets, and radio broadcasts aimed at undermining enemy morale and bolstering support among the local population. Its efforts included collaboration with South Vietnamese forces to influence perceptions and behaviors of both the Viet Cong and the civilian populace. The 4th PSYOP Group played a significant role until the drawdown of U.S. forces, after which it was inactivated as part of the overall reduction in American military presence in Vietnam.
