The 91st Infantry Division (famously nicknamed as the "Wild West Division" with a "Fir Tree" as its Division insignia to symbolize its traditional home of the Far West) was an infantry division of the United States Army that fought in World War I and World War II. From 1946 until 2008, it was part of the United States Army Reserve. It was briefly inactivated from 2008 until 2010 when it was elevated back to a division size element as the 91st Training Division (Operations).
Constituted on 5 August 1917 at Camp Lewis, Washington, near Tacoma, the division soon thereafter 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 World War I, the division, as part of the VII Corps of the French Sixth Army, helped drive the Germans east across the Escaut River. The division was awarded separate campaign streamers for its active role in the Lorraine, Meuse-Argonne and Ypres-Lys campaigns.
In 1919, the 91st was inactivated at the Presidio of San Francisco. After being reconstituted in 1921 as part of the Organized Reserves, the division then served as an administrative control center for the next 21 years.
The Division was composed of the following units:
