Plenty of them.Are there any old Soviet movies with a similar tone to Come and See, but focusing more on the combat aspect as opposed to life behind the lines?
For instance: Ballad of a Soldier, They Fought for Their Country, Battle of Moscow, The Dawns Here Are Quiet (my favourite one) and most epic war movie ever: Liberation series.
I may also recommend (commie) Polish ones: Direction Berlin and Last Days.
