21st Replacement Battalion

21st Replacement Battalion was activated on 20 October 1942 at Camp Sutton, North Carolina for services during World War II

On 18 March 1955 the 21st Replacement Battalion was reactivated at Zweibrucken, Germany, and in May of that year, moved to Frankfurt am Main due to the number of soldiers arriving at Rhein Main Air Base.

The Battalion was also located at Gutleut Kaserne where the Battalion remained for more than a decade. The Kaserne was near the main railway station which eased the movement of troops to their ultimate unit of assignment. 

On 31 December 1976 the 21st moved to temporary quarters on Hansa Allee near what is now called the Abrams Complex. Construction of new permanent facilities on Rhein Main Air Base began in August 1978. The new compound was completed and occupied in July 1980, where 21st Replacement Battalion remains today.
