An Overview US Army in Thailand
During Vietnam War (Era)
1962 - 1976
After WWII, the occupation of Japan and the Korean War armistice the United States was instrumental in putting together an Asian equivalent of NATO with the signing of the Manila Pact signed on 8 September 1954 leading to the creation of the Southeast Asian Treaty Organization (SEATO) and headquartered in Bangkok in 1955. SEATO was considered a concept of anti-communist collective defense to Southeast Asia whereby the military forces of each member were intended to be coordinated to provide for the collective defense of the member states.
During the 1950’s the civil war in the Kingdom of Laos grew and by the early 1960’s the Kingdom of Thailand requested and received assistance when it seemed that this internal war would spill over and into its borders.
The first US combat troops were stationed at Bangkok’s Don Muang Royal Thai Air Force Base, and consisted of 4 combat aircraft stationed on alert beginning April 1961. As communist aggression increased in the region by 1962 priority for US intervention to Thailand was favored over that in Vietnam. It wasn’t until the “Gulf of Tonkin” incident that President Johnson committed US forces to Vietnam, while bolstering US troop strength in Thailand as well.
Due to the nature of the “Gentleman’s Agreement” between Thailand and the United States that prevented other nations from knowing the full extent of the US involvement to protect its ally, all communications and/or news “officially” proclaiming the extent of this involvement was banned by the Thai government.
Officially all bases were “Royal Thai Bases” and were commanded by Thai commanders, yet command of US troops was retained by the United States. News and news organizations were not permitted to name actions originating from Thailand and US personnel were not given official recognition for injuries received in actions in Thailand.*
This became a “Secret War” and still today said recognition is being sought by personnel who were there “unofficially”.
The most noticeable were the air crews who flew combat missions into North and South Vietnam, Laos and even Cambodia.
Not seen were the Army Special Forces personnel training Royal Thai Police and Royal Thai Army units and personnel to fight Communist Thai (CT) and NVA insurgents throughout Thailand.
There were US Coast Guardsmen manning LORAN stations in not so noticeable locations throughout central and northern Thailand. US Army Engineers carved bases and roadways out of virtual jungle in demanding weather conditions?
Also unseen were the huge number of support troops who manned radio stations, field hospital and aid stations, motor pool dispatch offices and unit orderly rooms.
There were the military police and “top secret” recon patrols keeping an eye on things on “both” sides of the Mekong River.
It has been said that an army moves on its stomach. Well that stomach has to be fed. That is the job of the cooks and food preparation specialists. Before they can begin preparing their meals those rations and supplies have to be transported and disbursed to the respective bases and organizational mess or dining halls.
Another thing that fuels an army is funds. Everyone loves payday. Monies are received and paid out to various businesses and injected into the local economy through employment of local nationals at every level of the military. Military bases must be protected and defended in the event of subversive attacks.
Each of these unique functions is the specific responsibility of a host of military units of the various services within the US Department of Defense.
It is next to impossible to do justice to the virtually hundreds of military commands and organizations who made up this backbone within Thailand, yet each one is vitally important to the success and survival of the others.
I want to focus on facts that helped keep the Kingdom of Thailand from almost certain domination by the increasing communist threat in the region of Southeast Asia.
US ARMY IX CORPS
The US Army’s IX Corps located at Fort Buckner on Okinawa was the parent organization for US Army Special Forces units operating throughout Southeast Asia from early 1960’s throughout the mid 1970’s and for the 9th Logistical Command (B) and would later become the 9th Regional Support Command and ultimately the 9th Theater Army Area Command at Camp Zama, Japan in 1994.
In May 1962, the Military Assistance Command, Thailand was formed in Bangkok.
SEATO Exercise Air Cobra
In 1962 the escalation of hostilities in Laos led to SEATO Exercise Air Cobra taking place in Thailand with United States and Australian military forces as a show of force and solidarity with Thailand. As the hostilities began to subside and at the request of the Thai Government the 809th Engineer Battalion (Construction) prepared to begin construction of the Bangkok By-Pass Road from Chachaengsao to Kabin Buri.
In May 1962 Joint Task Force 116 (Army, Air Force and Marines) was created to conduct military operations along the Laotian border areas in support of Royal Thai military forces. Many of the units comprising the joint task force were stationed in Korea, Okinawa and Hawaii. This task force comprised of a Marine Battalion Landing Team (BLT), the 1st Battle Group, 27th Infantry (25th Infantry Division) and supporting elements under a detachment of the 9th Logistical Command. In August 1962, they were joined by an army aviation company composed of Caribou aircraft and the 1st Battle Group, 35th Infantry (25th Infantry Division) replaced the 27th Infantry. The task force was withdrawn in November 1962 after the situation in Laos stabilized.
9th Logistical Command (B)
Elements of the 9th Logistical Command (B) remained in Thailand as an administrative and logistical support headquarters overseeing the Communications Electronics Base, Thailand, Korat Army Depot and various construction projects, including the Sattahip Port Complex and the extension of the Bangkok By-Pass Road from Sattahip to Korat. All other 9th Logistical Command units moved from Okinawa to join the headquarters in Thailand. The 9th Logistical Command (B) was inactivated on 12 June 1970 at Camp Samae San, Sattahip.
On 25 April 1966 the United States Army Support Command, Thailand was activated on Okinawa and elements began deploying to Thailand on 17 October with the rear detachment closing on Camp Friendship on 15 November 1966. On 1 January 1967 USARSUPTHAI officially assumed command and/or operational control over all Army units in Thailand. The USARSUPTHAI was inactivated on 1 July 1974 at Camp Samae San, Sattahip.
The missions of USARSUPTHAI are as follows:
(1) Tactical: Provide the U. S. Army nucleus for a unilateral, bilateral or combined tactical headquarters to conduct ground combat operations in Thailand;
(2) Training: Conduct continuing OJT (on-the-job training) of assigned Army units;
(3) Planning: Conduct U. S. Army planning to support joint operational plans for current operations and contingency U. S. unilateral, bilateral and SEATO plans;
(4) Management: Exercise command management supervision of U. S. Army construction programs, logistic operations, real property, facilities and project stocks; and
(5) Logistical and Administrative: Provide
(1) Logistical support to U. S. Air Force operations in North Vietnam and Laos and
(2) U. S. Army and joint service support as directed.
All Army units in Thailand came under the operational control of USARSUPTHAI and played a vital part of the war in Vietnam and early on:
Detachments of the 46th Special Forces Company (Airborne) operated with and trained Royal Thai Army and Royal Thai Police personnel and provided medical support to a number of remote villages throughout northern Thailand.
The 428th Medical Battalion had responsibility for 2 field hospitals, the 5th Field Hospital in Bangkok and the 31st Field Hospital in Korat, plus a number of dental and medical detachments.
The 44th Engineer Group had overall responsibility for building infrastructure and roadway nets that would link each military base together, providing better access in an area primarily consisting of jungle growth utilizing units of the 809th Engineer Battalion and other engineer assets brought in for that specific purpose (quite a huge undertaking, even by today’s standards). The 697th Engineer Company (Pipeline) had the responsibility for constructing buildings, huge “Tank Farms” for fuel storage facilities, all the buildings and even the plumbing for every base in Thailand.
The 596th Quartermaster Company arriving in Thailand as part of the US Strike Command had the responsibility of operating those massive “Tank Farms” for each of the airbases to be used by United States Air Force personnel and fell under the 9th Logistical Command (B).
The USA STRATCOM Signal Battalion, Provisional had the responsibility of building and maintaining critical communications networks and links that would tie these military bases to the rest of the US Army forces in Southeast Asia and beyond.
The transportation needs of US forces would be met by two transportation battalions, the 499th Transportation Battalion (Terminal) and the 519th Transportation Battalion (Motor Transport).
The 499th was responsible for receiving cargo in country at the Deep Water Ports of Sattahip, the Ammunition Piers at Vayama and the Peers in Bangkok.
The 519th was responsible for transporting much of this cargo (in concert with the local ETO Company) from the ports all the way to destination (more than 1066 highway miles) utilizing Trailer Transfer Points strategically placed enroute at critical points (Sattahip, Korat and Khon Kaen).
The lifeblood of the entire US military operations depended upon their success.
These are the major commands that controlled much of the Army’s assets in Thailand:
Joint US Military Assistance, Thailand
Joint US Military Advisory Group, Thailand
Joint US Military Advisory Group, Thailand, Support Group, Provisional
Joint US Military Advisory Group, Thailand, Support Group A
US Army Bangkok Area Command, Provisional
