He’s an Old Guard guy, he is wearing a buff strap on his left shoulder. I know when I was there that was only awarded to Old Guard soldiers upon successful completion of “new man training”. TOG has the usual support positions you find in any other Infantry Battalion along with others not normally found. The Fife and Drum Corps is one example.
Thanks. Somebody pointed out that the gold badge above his right breast pocket was likely a set of foreign jump wings. I mistook them for a set of aviator’s wings.
