HISTORY
1961
In December 1961 as the first U.S. Army aviation units
arrived in Vietnam it became apparent that logistical support had to be
increased.
The 9th Logistic Command on Okinawa sent a logistic support team to South Vietnam on December 17, 1961.
This team would eventually become the headquarters of the U.S. Army, Vietnam, the Army component of the U.S. Military Assistance Command, Vietnam.
1962
On 15 May 1962 the U.S. Military Assistance Command, Thailand (USMACTHAI) initially consisted of the following: A U.S. joint task force (JTF 116) in Thailand deployed as an element of the SEATO exercise and later held there because of Communist activity in Laos; the Joint U.S. Military Assistance Group, Thailand (JUSMAG); and other U.S. Military elements deployed to Thailand, many from Okinawa. Army units in Thailand were placed directly under MACTHAI on October 30, 1962. The original designation of MACTHAI was U.S. Military Assistance Command, Vietnam-Thailand and called the Military Assistance Group in Thailand (MAGTHAI). MACTHAI would have operational control over all U.S. forces in Thailand.
1965
By the end of 1965 USMACTHAI and
MAGTHAI would be consolidated into a single command called MACTHAI.
1956
The history of the United States Army Support, Thailand (USARSUPTHAI) began as early as February 1956 as an element of IX Corps stationed in Okinawa. Known then as Headquarters IX Corps and assigned to Headquarters US Army Ryukyu Islands (USARYIS) as a planning group for Southeast Asia missions and exercises.
1966
When IX Corps reorganized, a Headquarters and Headquarters Company formed on April 25, 1966 began as the forerunner of Headquarters and Headquarters Company, USARSUPTHAI.

In October 1966, the first echelon of eleven officers and
twenty-eight enlisted arrived in Korat. Subsequent air and sea movements
followed on schedule and the headquarters closed at Korat on November 15, 1966.
