Of course I'm from the BDU era, 92-00, pre that awful beret.
Remember having to get all your tops sewn up any time you got a promotion or a new unit patch? Velcro has made that quite a bit easier. Plus you don't get your collar bones broken when you "rank up", now you just get a punch in the chest.:p
Let's see, when I was n the US Army, total rank insignia cost for me....$0 as it was issued to me upon promotion. Still should be free in game.
Must have been a long-ass time ago. For the last 6 of my years, you pay for everything. Granted, you do get a yearly allowance of $200 for uniforms. Also, any dry cleaning and sewing of insignia is tax deductible.
