The 1st Cavalry Division ("First Team") is a combined arms division and is one of the most decorated combat divisions of the United States Army. It is based at Fort Hood, Texas. It was formed in 1921 and served during World War II, the Korean War, the Vietnam War, the Persian Gulf War, with the Stabilization Force in Bosnia-Herzegovina, in the Iraq War, in the War in Afghanistan as well as Operation Freedom's Sentinel and Operation Inherent Resolve. As of October 2017, the 1st Cavalry Division is subordinate to III Armored Corps and is commanded by Major General John B. Richardson. The unit is unique in that it has served as a horseback cavalry division until 1943, an infantry division, an air assault division and an armored division during its existence. History The history of the 1st Cavalry Division began in 1921 after the army established a permanent cavalry division table of organization and equipment on 4 April 1921. It authorized a square division organization of 7,463 officers and men, organized as follows: Headquarters Element (34 men) Two Cavalry Brigades (2,803 men each) Field Artillery Battalion (790 men) Engineer Battalion (357 men) Division Quartermaster Trains Command (276 men) Special Troops Command (337 men) Ambulance Company (63 men) On 20 August 1921, the War Department Adjutant General constituted the 1st and 2nd Cavalry Divisions to meet partial mobilization requirements, and authorized the establishment of the 1st Cavalry Division under the new TO&E on 31 August 1921. Since 1st Cavalry Division was to assemble from existing units, it was able to go active in September 1921, even though the subordinate units did not arrive completely until as late as 1922. 1st Cavalry Division was assigned to the VIII Corps Area, with its division headquarters and 2nd Brigade located at Fort Bliss, Texas, and the 1st Brigade at Camp Harry J. Jones in Douglas, Arizona. The headquarters facilities used by 1st Cavalry Division were those previously vacated by 8th United States Brigade when it was commanded by MG John J. Pershing in 1916, and the wartime 15th Cavalry Division, which had existed at Fort Bliss between 10 December 1917 and 12 May 1918. The 1st Cavalry Division assembled at Douglas, Arizona. The 1st, 7th, and 8th Cavalry Regiments had previously been assigned to the wartime 15th Cavalry Division until they were returned to the VIII Corps Area troop list on 12 May 1918.
