In 1944-45 roughly 500,000 women were volunteer uniformed auxiliaries in the German armed forces (Wehrmacht). About the same number served in civil aerial defense, 400,000 volunteered as nurses and many more replaced drafted men in the wartime economy. In the Luftwaffe they served in combat roles helping to operate anti-aircraft systems to shoot down Allied bombers. By 1945, German women held 85% of the billets as clerics, accountants, interpreters, laboratory workers and administrative workers, together with half of the clerical and junior administrative posts in high-level field headquarters.
