Thank you, makes sense now. I was really bothered that they didn't even have the American Flag patch on their arms.
I guess they did it for continuity. They were from various branches, but they wanted them all dressed the same as if they were arriving as a unit. That is what I would suspect.
When R&R was first instituted the guys were plucked out the desert dirt & grim inclued and thrown on a plane home. They are no longer allowed to fly home like that. Either they keep one set of DCU clean and unworn (hard to do when they only issue you 2 sets) or purchase new before going home. If they are lucky enough to be in Kuwait long enough waiting for a flight they can get them cleaned and pressed, but much easier to purchase new just no time to sew on patches.
