The history of Warminster's military garrison can be traced back to Roman Britain, when a small camp was on the site of the current Battlesbury Barracks. However, under the Options for Change programme following the Dissolution of the Soviet Union and subsequent end of the Cold War, Headquarters, Combined Arms Training Centre in Warminster was dual-headed as Headquarters, Warminster Garrison and Warminster Training Centre on 1 April 1993. This itself was formed from a merger of the defunct Headquarters School of Infantry and the Barracks, Warminster (today known as Battlesbury Barracks). All three of these elements merged into the Warminster Training Centre (WTC).
