100th Div USAR

The 100th Division (Training), United States Army Reserve (USAR), was originally constituted in 1918 as the 100th Division during World War I, but it was demobilized shortly after the war ended. Reactivated in 1942 for World War II, the division distinguished itself in combat across France and Germany, earning a reputation for effectiveness and perseverance. After the war, the unit was reorganized as part of the Army Reserve, later transforming into a training division responsible for preparing new soldiers and leaders. The 100th Division has played a critical role in Army Reserve training missions, continuing its legacy of service and readiness into the 21st century.
