Thai Forces deploy to Vietnam War
On 18 September 1967, Thailand stood on the threshold of its largest commitment to the Vietnam War. Engineers and advance parties were already in South Vietnam, while the main body of the Royal Thai Army Volunteer Regiment, known as the “Queen’s Cobras”, was preparing to arrive.
Thai involvement had begun in 1964 when a small Royal Thai Air Force contingent arrived to fly and maintain transport aircraft. Thai pilots later operated C-123 Providers and C-47 Dakotas, while the Royal Thai Navy supplied ships and crews for coastal patrols and transport duties. Sending ground troops, however, represented a much greater commitment.
The government in Bangkok feared that communist expansion through Indochina would eventually threaten Thailand. Insurgents were already active within the country, particularly in the north-east, and Thai leaders believed it was better to confront the threat in Vietnam than wait for it to reach their own borders.
In January 1967, Thailand announced that it would send a reinforced combat formation to support South Vietnam. Thousands volunteered, including serving soldiers, civilians and several Buddhist monks. Although officially a volunteer regiment, most of its men were selected from existing Royal Thai Army units and retrained for service in Vietnam.
The Queen’s Cobras deployed with approximately 2,200 men. The force included four rifle companies, engineers, reconnaissance troops, signals, medical and transport personnel, military police, heavy weapons and a six-gun battery of 105mm howitzers. It was also equipped with M113 armoured personnel carriers, mortars, machine guns, M16 rifles and M2 carbines.
The deployment took place in stages. An engineer company left Bangkok aboard a Royal Thai Navy landing ship on 11 July and reached Newport Army Terminal near Saigon four days later. It then travelled by road to Bearcat Base near Bien Hoa to prepare accommodation, defences and facilities for the regiment.
An advance party flew into South Vietnam on 20 August. By 18 September, the preparations were complete and the principal movement was ready to begin. The main body arrived between 19 and 23 September, many aboard the American transport ship USS Navarro. The regiment’s armoured personnel carrier platoon followed in November, completing the deployment.
After landing, the Thai soldiers formed guarded convoys for the journey to Bearcat, which they shared with the US 9th Infantry Division. Their first weeks were spent completing field training, learning local conditions and conducting patrols alongside American and South Vietnamese forces.
The regiment was assigned to Bien Hoa Province, an important area north-east of Saigon containing villages, plantations, roads and supply routes used by the Viet Cong. Its duties included patrols, ambushes, convoy protection, village security and search-and-clear operations intended to disrupt communist movement and supplies.
In October 1967, the Queen’s Cobras launched Operation Narasuan, their first major independent operation. Thai soldiers searched the Nhon Trach district for Viet Cong fighters, weapons and hidden stores. Engineers also built roads, while medical teams treated thousands of Vietnamese civilians as part of efforts to reduce communist influence.
The Thai troops earned a reputation among their allies for discipline, determination and skill in jungle warfare. Many carried Buddhist amulets for protection, while their distinctive cobra insignia soon became a familiar sight around Bearcat and throughout their operational area.
After approximately a year, the regiment was replaced by the much larger Royal Thai Army Volunteer Force, known as the Black Panther Division. This formation eventually exceeded 11,000 men, showing how Thailand’s initial 1967 deployment had developed into a major commitment.
The events surrounding 18 September 1967 marked an important turning point. Thailand was no longer providing only aircraft, ships and small support detachments. With the arrival of the Queen’s Cobras, Thai soldiers entered the ground war in strength, beginning a combat deployment that continued until 1972.
