We Were Soldiers Once was one of my favorite. Saving Private Ryan is a great one too.
I watched Midway the past 2 days and thought it was pretty good.
Enemy at the Gates. All Quiet on the Western Front.... and I’m sure there’s several more that I’m forgetting but the first 2 I mentioned are some of my favorites.
Hacksaw Ridge, Fury, Inglorious Bastetds, etc were good movies but I classify them in a different category than a true war movie.
