I am not a big fan of the usual Hollywood style war movies like Saving Private Ryan, Black Hawk Down etc. Instead in the past years I learned to appreciate some of the war movies from the USSR and Russia, which often show the consequences of war for ordinary civilians and soldiers more realistic and without the usual cliches than many western films.
Here some examples:
I guess many have heard of Come and See (1985) by Elem Klimov:

An unusual war movie about a unit of young female anti-aircraft gunners is The Dawns Here Are Quiet (1972) by Stanislav Rostotsky:

Prisoner of the Mountains (1996) by Sergei Bodrov is set in the first Chechen War and loosely based on a short story by Leo Tolstoy:

The Cuckoo (2002) by Aleksandr Rogozhkin is a story about a Finnish and a Soviet soldier and a Sami woman during the Continuation War:
