Back to TOC
I Field Force, Vietnam, was organized in August 1965, as Task Force Alpha to control all U.S. Army forces in Vietnam. Shortly, however, the mission was changed to control over forces in II Corps. In November 1965, Task Force Alpha was renamed Field Force Vietnam. The command became I Field Force in March 1966, when a second field force was organized in III Corps. Currently, the major units under operational control of I Field Force include the 4th Infantry Division; the 173rd Airborne Brigade; Task Force South the 17th Combat Aviation Group, and Company B, 5th Special Forces Group. The battalions of I Field Force Artillery provide support for all major U.S. and Allied combat operations. The complex communications network in II Corps is operated by the 54th Signal Battalion. Task Force South was organized in July 1968 to increase pressure on enemy forces operating in the four southern provinces of II Corps. It is a force made up of combat units from the 4th Infantry Division, 173rd and the 101st Airborne Division (Airmobile) with armor, helicopter and artillery support. Task Force South's command element is co-located with the Light Infantry Command Post of the Army of the Republic of Vietnam (ARVN) 23rd Infantry Division. Coordinated operations have resulted.
