I don't see these mentioned too many times ... I highly recommend them, you should at least check out a review of each on IMDB.com
Not all are known to be super accurate, however, these are all great movies
Enemy At the Gates.... The battle scenes in this movie scare the hell out of me
Memphis Belle............ B17 crew final mission movie
Kelly's Heroes............ Get the gold!
the Dirty Dozen.......... Buncha criminals kick nazi a$$
The Great Escape....... Good movie, though it has it's share of innacuracies.
The Tuskegee Airmen. African Americans make good fighter pilots too
Where Eagles Dare..... (not based off of any real battles, still interresting)
