The Auxiliary Territorial Service (ATS) was a women's branch of the British Army during World War II, established in 1938. Its primary purpose was to free up men for combat roles by allowing women to take on various support positions. Members of the ATS performed tasks such as driving, clerical work, and communications, contributing significantly to the war effort. Women in the ATS wore uniforms similar to their male counterparts and were involved in various military operations. The service was instrumental in changing perceptions about women's roles in the military, paving the way for future integration of women in the armed forces, including the Royal Army and Royal Air Force.
