Height-Finder and Crew A lance bombardier, height-finder commander of the ATS (Auxiliary Territorial Service). The expansion of the AA gun defences during the war, coupled with the drain of able-bodied men to serve in fighting units overseas, brought ATS women into gun batteries to perform active roles. Although it was considered inappropriate for women to operate guns, they operated other items of equipment at gun sites. This girl wore standard army pattern overalls, with a service greatcoat for added warmth. She wore a Mark I steel helmet with the strap behind her neck. The thick khaki scarf, probably knitted by herself, was an unofficial addition to help keep out the cold. Drawing by Darko Pavlovic
