Far East Command (FECOM) was a unified combatant command of the United States Department of Defense, active from 1947 until 1957, functionally organised to undertake the occupation of Japan and Korea. The 1st and 6th Marine Divisions (China Marines), who from 1945 to 1948 assisted the Chinese government in occupying northern China, disarming the Japanese, and helping the Kuomintang Chinese without fully getting involved in the Chinese Civil War, were not part of Far East Command and reported to Pacific Command and the U.S. Navy.
