Yes , the nineties German made film Stalingrad comes to mind , gritty film .And of course Das Boot .What did you think of Fury with Brad Pitt about the Sherman tank crew , not too bad apart from the overdone ending.Those are great films but there are some great modern ones out there, International ones if you don't mind subtitles, There is on Youtube a countdown of Top 10 Russian war films and I've seen a lot of them, That's worth a look for some ideas, They are cracking films, Also some German made ones too.
