The V Amphibious Corps (formerly Amphibious Corps, Pacific Fleet; ACPF) was formed on 25 August 1943 at Camp Elliot, California. In September 1943, it moved to Pearl Harbor, Hawaii.


The structure of a United States Marine Corps' amphibious corps by 1945, was broken down into four major subordinate commands with each of them having numerous sub-elements:

  • The first major element of the Corps was three reinforced Marine infantry divisions.
  • The second was the Corps artillery, which was composed of a field artillery group made of three battalions of 155mm howitzers, three battalions of 155mm guns, and an Antiaircraft Artillery Group made of three antiaircraft artillery battalions.
  • The third was the Amphibian Tractor Group, which was made up of four amphibian tractor battalions and an armored amphibian tractor battalion.
  • The fourth was the Corps Troops, which was composed of a headquarters and service battalion, administrative command, signal battalion, medical battalion, motor transport battalion, engineer battalion, reconnaissance battalion, and military police battalion.[1]
