Ok, just read the whole thread. I can't believe "Cross of Iron" (1977) wasn't mentioned.
http://www.imdb.com/title/tt0074695/?ref_=fn_al_tt_1From IMDB: "In 1943, in the Russian front, the decorated leader Rolf Steiner is promoted to Sergeant after another successful mission. Meanwhile the upper-class and arrogant Prussian Captain Hauptmann Stransky is assigned as the new commander of his squad." From legendary director Sam Peckinpah, he was know for being very bloody and gory for his day. Rare for an American WWII film from the 70's to be about the Eastern front. Features James Coburn and lots of PPSH action.
Watch it on Youtube-
https://www.youtube.com/watch?v=2-_on1wmZxIFor the classic 'steal the Nazi gold from behind enemy lines' plot-line, there's "The Last Drop" (2006). Not much for WWII story, more for the setting, but some funny moments, and simply excellent characters. Billy Zane (who played 'Val' in "Memphis Belle") has one of the best lines as a Canadian pilot. I don't want to give any spoilers.

http://www.imdb.com/title/tt1029235/?ref_=nv_sr_1 Sorry, I couldn't find a free, streaming version of this one. It used to be on Netflix, it might still be.
"Company of Heroes" (2013) Was absolutely dreadful. I couldn't even finish it. How do you make a boring WWII movie!?! Not even Tom Sizemore (Sgt Horvath from "Saving Private Ryan") could save this movie.
http://www.imdb.com/title/tt2555426/?ref_=fn_al_tt_1I can't believe nobody mentioned the 2013 Russian film "Stalingrad" (I saw a couple people talked about the German (1993) one) and also "Attack on Leningrad" (2009) both are must-see films even if you aren't a WWII film buff.
