For the nations who were deeply involved in World War II, the war effort was total, with women volunteering in huge numbers alongside men and filling traditionally male positions at home, in industry, and the military. Women took both active and supporting positions in factories, government organizations, military auxiliaries, resistance groups and more. While relatively few women were at the front lines as combatants, many found themselves the victims of bombing campaigns and invading armies. By the end of the war, more than 2 million women worked in war industries, hundreds of thousands volunteered as nurses or members of home defense units, or became full-time members of the military. In the Soviet Union alone, some 800,000 women served alongside men in army units during the war. Collected here are images of women involved directly in the events of World War II, and some of what they experienced and endured.
