The V Amphibious Corps (VAC) was a formation of the United States Marine Corps which was composed of the 3rd, 4th and 5th Marine Divisions in World War II. The three divisions were the amphibious landing force for the United States Fifth Fleet and were notably involved in the battles for Tarawa, Saipan, and Iwo Jima, during the war. The V Amphibious Corps was commanded by General Holland 'Howlin Mad' Smith followed by General Harry Schmidt.
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.
