The womens corps of the British Army was formed initially in 1938 as The A.T.S (Auxiliary Transport Service) & was redesignated as an official corps on 1st February 1949. The Corps lasted until 1992 when it was disbanded & staff transferred to The Adjutant Generals Corps. 

The idea to merge all women apart from certain exceptions into one corps & their key role was administrative & supportive tasks.
