Sixth Army is a field army of the United States Army, headquartered at Fort Sam Houston; it is the Army service component command of United States Southern Command. Its area of responsibility includes 31 countries and 15 areas of special sovereignty in Central and South America and the Caribbean.


It was first activated in January 1943, commanded by Lieutenant General Walter Krueger.[1] Under the code name Alamo Force,[2] it assumed control of the majority of US Army units involved in Operation Cartwheel, the campaign to isolate and neutralize the Japanese base at Rabaul in New Britain. Following the completion of Cartwheel, Sixth Army joined Australian Army and other US forces on the north coast of New Guinea.[3] Similar in conception to the island hopping operations of the central Pacific, the object of the attacks was to land, establish a garrison and airfield which could support the next strike, and then move on.

In September 1944, Sixth Army was released from operations in New Guinea by the Eighth United States Army. On 20 October 1944, X Corps and XXIV Corps, under Sixth Army, invaded Leyte in the Philippines. By December, Leyte was secured, and the Sixth Army was relieved again by Eighth Army to prepare for the invasion of Luzon.[4] As a prelude to that invasion, the island of Mindoro was invaded by the Western Visayan Task Force comprising the 19th and 503rd Regimental Combat Teams.[5] Sixth Army took part in the Invasion of Lingayen Gulf[6] on 9 January 1945 with the subordinate units of I and XIV Corps.[7] Sixth Army units fought south until they met up those of Eighth Army advancing from around Manila. Sixth Army then continued to clear the north of Luzon until the end of the war. Sixth Army was to have provided the ground forces for the first phase of the invasion of Japan, but the surrender changed that.[8]

Occupation duty then followed for a short while until Sixth Army returned to the United States,[9] headquartered at the Presidio of San Francisco. Sixth Army then took responsibility for training of Army forces from part of the continental United States, until it was inactivated as part of force reductions in June 1995.[10]


In 2007 it was decided that US Army South will be redesignated as US Army South (Sixth Army) under the Army modularization program.[11][12] It is garrisoned at the Old Brooke Army Medical Center building at Fort Sam Houston.[13]
