Navy from the old days (background) Naval officers assigned to aviation billets from World War II through Vietnam were authorized Aviation Greens in addition to their standard Navy blue uniform. The cut was very similar to Marine greens except that there was no belt. Rank insignia was in black and they wore a khaki shirt and black necktie. The shoes were lighter brown than the standard Marine Corps issue of the time and they wore tan socks. The Naval Aviator wings were gold-embroidered and the fore and aft cap had small solid gold wings on the port side and rank insignia on the starboard.
