91st Division (Training Support)

Definition/Scope: The 91st Division (Training Support) is organized and staffed to plan, conduct and evaluate training exercises (including small unit collective training) for the Army National Guard, Army Reserve Combat Support and Combat Service Support Units at the squad, platoon/section, and company/battery levels and above. Upon mobilization, the 91st Division will assist in the validation of Reserve and Army National Guard units in the preparation for deployment. The division has also deployed Soldiers to Southwest Asia in support of Operations Enduring Freedom and Iraqi Freedom. It trains Army Reserve combat support and combat service support units and Army National Guard Brigade Combat Teams for deployment in support of those operations. Constituted on August 5, 1917, at Camp Lewis, Wash., the division soon departed for England in the summer of 1918. In September 1918, the division’s first operation was in the St. Mihiel Offensive in France. Serving under the U.S. Army’s V Corps, the division fought in the Meuse-Argonne Offensive and successfully helped to destroy the German First Guard Division and continued to smash through three successive enemy lines. Twelve days before the end of WWI, the division, as part of the VII Army Corps, helped drive the enemy east across the Escaut River. The division was deactivated at Fort Rucker, Ala., in December 1945. In December 1946, the 91st was reactivated at the Presidio of San Francisco as part of the U.S. Army Reserve. In 1959, the division was reorganized and redesignated as the 91st Division (Training). In 1993, the division was again reorganized and redesignated as the 91st Division (Training Support). The ongoing transformation of the Army Reserve has the 91st Division scheduled to be redesignated as the 91st Training Brigade (Operations) effective 1 October 2009.
