AFRTS stations in Vietnam were initially known by the name "AFRS" (Armed Forces Radio Saigon), but as the number of stations quickly expanded throughout South Vietnam became known as "AFVN" (American Forces Vietnam Network) and had several stations, including Qui Nhơn, Nha Trang, Pleiku, Da Nang and Huế, the latter being overrun by the People's Army of Vietnam during the Battle of Hue in January/February 1968 and replaced by a station in Quảng Trị. AFVN's headquarters station was located in Saigon.
