Lotta Svärd
During the Winter War some 100,000 men whose jobs were taken over by "Lottas" were freed for military service. The Lottas worked in hospitals, at air-raid warning posts and other auxiliary tasks in conjunction with the armed forces. The Lottas, however, were officially unarmed. The only exception was a voluntary anti-aircraft battery in Helsinki in the summer of 1944, composed of Lotta Svärd members. The battery operated the AA search-lights. The unit was issued rifles for self-protection, thus being the only armed female military unit of the Finnish Defence Forces history.
