About this Unit
The **Military Assistance Command, Vietnam – Headquarters Support Group (MACV HGS)** was a vital component of the United States military presence in Vietnam between 1962 and 1973. Established to provide essential administrative, logistical, and operational support to MACV headquarters in Saigon, HGS managed services such as communications, transportation, and base security for American and allied personnel. The unit enabled the smooth functioning of MACV’s command structure, facilitating coordination among various branches and international partners engaged in the Vietnam War. As U.S. involvement in Vietnam drew down, MACV HGS played a key role in the phased withdrawal and redeployment of American forces before its deactivation in 1973.
