This looks really, really nice. Have been longing for a way to give the soldiers some more memorable identity. I like and care for my guys, they should not be throwaway cannonfodder and should look badass, even if we're in the dreary cold war era. Absolutely loving the heads and outfits, even if there are some familiar faces in there.
My only gripe is their stance, the males especially. Firstly, I feel like it's a bit of a shame to hide the hands behind their back so we can't see the entire outfit, but that's a minor thing - the hands behind the back looks cool also. But secondly and more importantly, something about their leg-pose seems very strange somehow. They do not look very relaxed, almost like the feet are bent at a strange angle. Is it just me? Personally I'd prefer a more relaxed "at-ease" look to them.
But keep up the fantastic work nonetheless, I'll be sure to try this mod out.
