The 2nd Marine Corps Battalion was established at Sattahip in 1937. Two years later, the 2nd Battalion was expanded into the Marine Corps Department. Shortly after that, a border dispute with French Indo-China turned violent, and the Marine Corps Department's "Chanthaburi Division" was engaged in action with the French Foreign Legion several times. During World War II, the Marine Corps sent troops to defend the southern border with Malaya and also guarded Phuket Province from possible attack.
