Voluntary Legion of Women
Voluntary Legion of Women (Polish: Ochotnicza Legia Kobiet (OLK)) was a voluntary Polish paramilitary organization, created by women in Lviv in late 1918. At that time possession of the city was contested by the Poles and Ukrainians, and women decided to assist the Polish soldiers in all possible ways, including fighting on the front line.
