"Women Urgently Wanted for the W.A.A.C Women's Army Auxiliary Corps," circa 1917

Over 50,000 British women volunteered with the Women's Army Auxiliary Corps (WAAC) during the last two years of World War I. WAAC volunteers took on non-combat support roles at home and on the frontlines in France and Belgium. It was the first time that women were allowed in the British armed forces in an official capacity outside of nursing.
