Well, as an old Army fella' that recently retired and still works as a civ with the militar, I have seen a lot of changes in uniforms..One of the funniest was when the Navy switched to "blue" camos....I took one look at the guy and asked How do they find you if you fall in the water?...So switching to grey at least makes bette sense then what htey have right now. No offense to the Navy.
Saying all that the Army is switching uniforms again also, but being an old sniper I kinda like the patten they are using... Makes sense finally.
