I have to say, I am very pleasantly surprised by all of the positive posts here. Except for a very small minority, most of the posts agree with the idea of supporting the troops with upgrades. ^ I say this because I personally have gotten into it several times in the past with some of the more "berkleyish" members of FT that would rather scold members of the military than show them any appreciation.
That said, I'd like to add that if you see a Marine flying in a tan digital camouflage uniform, they are most likely returning to or from a combat zone. Marines are not normally allowed to wear these uniforms in public except in a circumstance like that. I don't think the Army or other services follow this same rule, although that certainly doesn't mean they are not returning from combat.
