It reminded me a lot of "The Steel Helmet"; a tough look at warfare and how it affects the men involved. War is brutal in this film, and is portrayed as such. There are a lot of interesting camera movements/moments, pretty good acting all around, and at the end: Aldo Ray

wields a flame thrower to take out some remaining Koreans, which is pretty awesome.
(PS. Mann's birthday is Wednesday and TCM is showing more of his flicks then)
