...А зори здесь тихие (1972)

In a remote village in Karelia, Sergeant Vaskov commands an anti-aircraft unit that protects a rail depot. While his men are transferred to the front line, he is reprimanded for their unruly behavior. He retorts that he wants replacements that aren't drunks or womanizers. In response, he is assigned a unit made up entirely of young women, fresh from training.
