The Royal Thai Marine Corps (Thai: นาวิกโยธินแห่งราชอาณาจักรไทย) are the marines of the Royal Thai Navy.
 The Royal Thai Marine Corps was founded in 1932, when the first battalion was formed with the assistance of the United States Marine Corps.
 It was expanded to a regiment in 1940 and was in action against communist guerrillas throughout the 1950s and 1960s.
 During the 1960s the United States Marine Corps assisted in its expansion into a brigade.

3d Light Antiaircraft Missile Battalion (3d LAAM Bn) was a United States Marine Corps air defense unit equipped with the medium range surface-to-air MIM-23 HAWK Missile System.
 During World War II, the battalion was known as the 3rd Defense Battalion and took part in combat operations at Pearl Harbor, Midway, Guadalcanal and Bougainville.
 The unit was deactivated in late 1944 but was brought back into service as the Marine Corps began to transition to surface to air missiles for their air defense needs in the early 1950s.
 During the mid to late 1950s, the battalion was based at Marine Corps Training Center 29 Palms, California and was one of two Marine Corps units that operated the land-based version of the RIM-2 Terrier Missile.
 In January 1963 3d LAAM battalion was moved to Marine Corps Air Station Cherry Point, North Carolina and would eventually fall under the command of Marine Air Control Group 28 (MACG-28) and the 2nd Marine Aircraft Wing (2nd MAW).
 3d LAAM Battalion's final combat tour saw it providing air defense for the Marine Corps area of operations during Operation Desert Shield/Desert Storm.
 3d LAAM Battalion was deactivated on 30 September 1994 as part of the post-Cold War draw down of forces and because the Marine Corps had made the decision to divest itself of its medium-range air defense.
