The Supreme Command Headquarters of the Royal Thai Armed Forces was originally a temporary position that had only been called into existence twice: once, during the Franco-Thai War in 1940 and again during the Greater East Asia War (Second World War: Pacific Theatre). During both of these conflicts, the headquarters was commanded by Field Marshal Plaek Pibulsonggram, the prime minister of Thailand and creator of the supreme command system. Temporary personnel were called from their existing units and released after conflict subsided in 1945.
