Really, it's a case of apples and oranges.....
I am a 'combat arms type', and I didn't wear an OTW shirt for the simple reason that I couldn't justify spending $120 on something that I would most likely burn at the end of the tour. But if a JTF-A Air Wing dude wants to wear one, and his buddy doesn't, I really don't care whatsoever. I care that he can do his job and keep the airframe I am sitting in up and flying around, and not a flaming ball of wreckage somewhere. Just as he would care, if he found himself on a dismounted patrol, that I do my job well and keep him from getting blown up.
