U. S. Marine Corps Medals, Badges and Insignia of the Vietnam War, An Illustrated Guide 1960-1973 

thanks, that keeps us going!

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. 2001 is why i did not put it in the RVN era book. Good question!
