About this Unit
The 21st Replacement Battalion was a United States Army unit activated during World War II to provide trained personnel replacements for frontline combat units in the European Theater. Stationed primarily in France and Germany after the D-Day invasion, the battalion processed and assigned thousands of soldiers to depleted infantry, armor, and support units. Its role was critical in maintaining the fighting strength of Allied forces during major campaigns, including the Battle of the Bulge and the final push into Germany. After the war, the battalion was inactivated as the Army demobilized and reduced its overseas presence.
