United States naval diver insignias 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. In 2001, the Marine Corps authorized the creation of a new badge, the
Combatant Diver Insignia, attesting to the wearer's closed-circuit
rebreather and reconnaissance combat diver training; the gold-colored combatant diver insignia depicts a
wetsuit hood, low-profile diving mask, and chest-mounted
rebreather. The naval deep sea diver qualification insignia are awarded in four degrees: second-class diver; first-class diver; master diver; and diving officer. However, the Marine Corps does not award the Diving Officer Insignia to its officers. In the Navy, the master diver is the most qualified diver; he must be a chief petty officer before applying to attend the master diver course. The Diving Medical Officer Insignia and the Diving Medical Technician Insignia are awarded to naval medical personnel qualified as divers or medical technicians, respectively. The Diving Medical Insignia resembles the Master Diver Insignia, but is decorated with a
caduceus. The Diving Medical Officer Insignia is gold in color while the enlisted version—the Diving Medical Technician Insignia—is silver in color. Since the Marine Corps and the Coast Guard have no organic medical officers, they do not issue the Diving Medical Officer Insignia. ==United States Army==
