III Marine Expeditionary Force (III MEF) is a formation of the Marine Air-Ground Task Force of the United States Marine Corps. It is forward-deployed and able to deploy rapidly conduct operations across the spectrum from humanitarian assistance and disaster relief to amphibious assault and high-intensity combat.
It maintains a forward presence in Japan and Asia to support the Treaty of Mutual Cooperation and Security between the United States and Japan (1960) and other alliance relationships of the United States. III MEF also conducts combined operations and training throughout the region in support of the National Security Strategy for Theater Security Cooperation.
The Marines and sailors of III MEF engage in more than 65 combined, bilateral and multi-lateral training exercises annually throughout the Asia-Pacific region, in countries including treaty allies Japan, the Kingdom of Thailand, the Republic of Korea, the Republic of the Philippines, and Australia. These exercises build partner capacity, develop and maintain strong regional alliances and military-to-military contacts. These exercises prepare III MEF to conduct operations ranging from major combat operations to humanitarian assistance and disaster relief (HA/DR).
III MEF has played a significant role in humanitarian assistance and disaster relief missions throughout the region. The MEF assisted the relief efforts led by the Government of Japan during Operation Tomodachi after an earthquake and tsunami struck Honshu March 11, 2011. III MEF also conducted HA/DR missions in Thailand in Oct. 2011, the Republic of the Philippines in Oct. 2010, and Indonesia in Oct. 2009.
Commanded by a lieutenant general with its headquarters at Camp Courtney, III MEF's mission is to provide forward based and deployed forces to the commander, U.S. Pacific Command, to conduct Phase 0 engagement and theater secutiry cooperation events, support contingencies and emergent requirements, and prepare to rapidly execute existing operations plans in support of the theater and national military strategies.
III MEF is organized as a Marine Air Ground Task Force (MAGTF) to provide a rapidly deployable, flexible self-contained fighting force. The Marines combine air, ground, and logistics forces to operate as a coherent, self-sufficient force. Each mission dictates the MAGTF's scale and structure, giving the Marine Corps the flexibility to respond to any crisis and making a "force in readiness." A MEF is the largest of all MAGTFs.
III Marine Expeditionary Foce was activated as I Amphibious Corps Oct. 1, 1942 in Camp Elliott, San Diego, Calif. Later that month, they were deployed to Noumea, New Caledonia. The unit was redesignated as III Amphibious Corps April 15, 1944. III Amphibious Corps was deactivated June 10, 1946.

During World War II, III MEF was known as I Marine Amphibious Corps was renamed III Amphibious Corps on April 15, 1944, and took part in fighting against the Japanese Empire in the Pacific theater during World War II.

III Amphibious Corps redeployed to Tientsin, China in Sept. of 1945 where it participated in the occupation of Northern China until June 1946. III Amphibious Corps was deactivated June 10, 1946.
III MEF was reactivated May 6, 1965 in Da Nang, Republic of Vietnam. May 7, 1965, III MEF was redisgnated as III Marine Amphibious Force (III MAF) and consisted of the 1st Marine Division, 3rd Marine Division and the 1st Marine Aircraft Wing. The III MAF's area of operations was in the northern I Corps Tactical Zone. III MAF participated in the Vietnam War from May 1965-April 1971 operating from Quang Tri, Thua Thien, Quang Nam, Quang Tin, and Quang Ngai. III MAF deployed to Camp Courtney, Okinawa in April 1971.
