Patrick Swayze, C. Thomas Howell, and Charlie Sheen in Red Dawn (1984)
OK, this one is a bit of a stretch (like the plot) because only the bad guys wear uniforms. But nearly every single person in the original Red Dawn had a sort of post-apocolyptic meets rural Colorado hotness going on about them, especially Patrick Swazye, Charlie Sheen, and Jennifer Grey. Oh, and everyone carries a gun. Everyone. Paging Dr. Freud.
