Fourth United States Army

The 4th U.S. Army (English: Fourth United States Army ) was an Army major unit of the United States Army that existed from 1922 to 1971.

History

The 4th U.S. Army was set up in 1922 in New York as the Association of United States Army Reserve. On 9 August 1932, she was withdrawn and assigned as one of four active armies of the regular army of the reserve. The headquarters was in the summer of 1932 in Omaha, Nebraska, and from June 1936 at the Presidio of San Francisco. After the "Joint Action " plan of 1935, the Army was given the responsibility for the defense of the Pacific coast. In March 1941, the Western Defense Command was established under the jurisdiction of the army, which it was assumed. After the USA entered the war in December 1941 it became the Western Theater of Operations. From March to November 1942, the army was involved in the forced relocation of 110,000 Japanese- Americans from the West Coast in rear areas.

On January 7, 1944, the headquarters of the army to Fort Sam Houston, Texas, relocated there to take over the tasks of the intended for use in Europe and 3rd U.S. Army. The 4th Army was involved in the formation of combat troops, from which the 9th and 15th U.S. Army were formed.

After the war the army was responsible for recruitment and training in the southwestern United States. In July 1971, she was united in Fort Sam Houston with the 5th U.S. Army and thereby dissolved.
