91st Infantry Division:
The Powder River Division.

The 91st Infantry Division was activated as a component of
the Army of the United States on August 15th, 1942, with
Headquarters at Camp White, Oregon. After participation in
training exercises at the Bend River Maneuver Area in central
Oregon, the Division moved to Camp Adair, Oregon, where it
remained until it embarked for overseas in April of 1944.

The shoulder patch worn by the 91st Division is based on a
WW I design approved by the AEF on December 8th, 1918.
The evergreen tree is a sign of readiness and is typical of
the far west where the unit was formed. The Division's
nickname (which is also part of the battle cry) came from a
WW I incident when a sergeant asked a group of soldiers where
they were from. The soldiers were from the Powder River country
of Montana and shouted in reply, "Powder River! Let 'er buck!"
