United States naval diver insignia are awarded, per degree of qualification, to Sailors, Marines, and Coast Guardsmen. The elementary naval diver insignia is the Scuba Diver Insignia, awarded upon qualifying as a basic naval diver. Previously, the Scuba Diver Insignia was awarded in two degrees, one for officers and one for enlisted. The Navy eliminated the Scuba Diver Officer insignia in the 1990s, but it remains in service within the Coast Guard. The silver-colored insignia features an old-fashioned diving mask and open-circuit breathing apparatus.
