increasing the scale and scope of its assistance to Vietnam, as a renewed demonstration of Free World determination to work together to repel Communist aggression. It is, of course, for you to weigh and decide what it is practicable for you to do without undermining vital programs designed to thwart Communist designs on Thailand itself....
Beginnings of Thai Assistance
The first contribution to the Vietnam War effort by Thailand was made on 29 September 1964, when a sixteen-man Royal Thai Air Force contingent arrived in Vietnam to assist in flying and maintaining some of the cargo aircraft operated by the South Vietnamese Air Force. As an adjunct to this program, the Royal Thai Air Force also provided jet aircraft transition training to Vietnamese pilots.
The status of this early mission changed little until the Royal Thai Military Assistance Group, Vietnam, was activated on 17 February 1966 and a Thai Air Force lieutenant colonel was designated as commander. The Royal Thai Air Force contingent then became a subordinate element of the Royal Thai Military Assistance Group, Vietnam.
In March the commander of the Thai contingent asked the U.S. Military Assistance Command to furnish one T-33 jet trainer from its assets to be used for jet transition training previously given South Vietnamese pilots in Thailand. This training program had been suspended the preceding month because of a shortage of T-33's in the Royal Thai Air Force. The Thais had also requested two C-123 aircraft with Royal Thai Air Force markings to allow the Thai contingent to function as an integral unit and to show the Thai flag more prominently in South Vietnam. General Westmoreland replied that jet transition training for Vietnamese pilots was proceeding satisfactorily and that a T-33 could not be spared from MACV resources. He suggested that the aircraft be procured through the Military Assistance Program in Thailand. However, MACV did grant the request for C-123's; the commander of the Pacific Air Force was asked to provide the aircraft. The commander stated that C-123 aircraft were not available from the United States and recommended bringing Thai pilots to South Vietnam to fly two C-123's owned and maintained by the United States but carrying Thai markings. Arrangements were made to have these pilots in Vietnam not later than 15 July, assuming the Thai crew members could meet the minimum proficiency standards by that time. The crews, consisting of twenty-one men, became operational on 22 July 1966 and were attached to the U.S. 315th Air Comman[do]
