History

World War II

XXIV Corps was activated at Fort Shafter, Hawaii, on 8 April 1944. It participated in the invasion of Leyte in the Philippine Islands on 20 October 1944, with the 7th Infantry Division and 96th Infantry Division its major combat units. During the campaign on Leyte and aided by Filipino regular and constable force of the Philippine Commonwealth Army and Philippine Constabulary military units, the 77th Infantry Division came under control of XXIV Corps.

From 1 April to 30 June 1945, XXIV Corps and its divisions participated in the invasion of Okinawa. In September 1945, after the surrender of Japan, XXIV Corps moved to Korea, where it remained on occupation duty until its inactivation on 25 January 1949.

Vietnam

XXIV Corps was created on 15 August 1968 to replace the "Provisional Corps Vietnam," a temporary headquarters (known as MACV Forward Command Post or MACV Forward between 25 January and 10 March) created 10 March 1968 during the Tet Offensive. Upon its formation, XXIV Corps was placed under the operational control of the III Marine Force to control the activities of U.S. Army ground combat units deployed in northern South Vietnam and had its headquarters at Phu Bai until 9 March 1970, when it relocated to Camp Horn, Da Nang. At that time it assumed control of all U.S. ground forces in I Corps Tactical Zone (I CTZ), with all remaining Marine units coming under its operational control until their withdrawal. During its service in Vietnam XXIV Corps was a component command of Headquarters, US Army Vietnam (USARV).
