For clarity, the armor I showed for Reach is the actual Marine armor you see when the Marines touch down in the Pelican at the very end and when you attack the Solstice.
And yeah I was thinking of putting in the Halo Wars armor which I also love, but it's so similar to the Halo 3 armor that it ended up basically just being that with some pretty reflections and new knee and elbow pads, so I left it out.
Oh, and I'm not sure how Reach having outdated gear makes much sense. For starters it's Reach, and the Marines were coming from the Pillar of Autumn, a Marine ship. I don't see why they'd be given crappy gear seeing as as far as we know, the UNSC Marines are not locally based units.
