3/26 in Vietnam
The battalion was activated on 28 May 1966 under the command of Major William A Thompson.
After training at Camp Pendleton, CA and in the Philippines 3/26 arrived in Vietnam on 11 December 1966.
The battalion was originally under the Operational Control (OPCON) of the 3rd Marine Division. In May 1968 3/26 was reassigned to be OPCON to the 1st Marine Division.
3/26 departed Vietnam on 19 March 1970 and returned to Marine Corps Air Station El Toro CA where they were greeted by the Commandant of the Marine Corps.
The deadliest month in the battalion history was September 1967 when 3/26 operated in the northern I Corps near C2 and Con Thien.
