Really interesting stuff, there's a fantastic wartime film 'The gentle sex' about ATS recruits. Some of the footage and women in it are real ATS and there's a great section about the AA Batteries. It's regularly on Film 4.
Those women were in very real danger and many died through enemy action or in accidents, always akes me smile when people talk about women not playing a 'front line' role in the Great War or WW2.
