All-female units of the paramilitary Red Guards served in the 1918 Finnish Civil War. The first Women's Guards units formed in early February in the main Finnish cities. More than 15 female Guards units were established by the end of March 1918, with a total of about 2,000 women serving. The female Guards units consisted of young industrial workers, maids, and servants. Their average age was about 20, but some were as young as 14. The women served in auxiliary units in combat.
