A Glance at III MEF History

Early Years

III MEF was established as I Marine Amphibious Corps on Oct. 1, 1942. It was renamed III Amphibious Corps, April 15, 1944, and contributed to noteworthy military campaigns, such as the Solomon Islands campaign, the Mariana and Palau Islands campaign, and the Battle of Okinawa, during World War II.

 

In September 1945, III AC redeployed to Tientsin, China, and supported the occupation of Northern China before being deactivated June 10, 1946.

 

III AC was reactivated on May 6, 1965 in Da Nang, Republic of Vietnam, and redesignated III Marine Amphibious Force on May 7, 1965. III MAF, which consisted of 1st Marine Division, 3rd Marine Division and 1st Marine Aircraft Wing, operated in Quang Tri, Thua Thien, Quang Nam, Quang Tin, and Quang Ngai from May 1965 to April 1971 during the Vietnam War.
