821st Combat Security Police Squadron

The 821st Combat Security Police Squadron was a United States Air Force unit activated during the Vietnam War era. Established in 1966, the squadron was tasked with providing air base ground defense and security for critical USAF installations, including Phan Rang Air Base in South Vietnam. Its personnel conducted perimeter defense, rapid response to enemy attacks, and patrolled base surroundings to deter Viet Cong and North Vietnamese Army infiltrations. The unit was inactivated in 1972 as American military involvement in Vietnam decreased and bases were handed over to South Vietnamese control.
