First created in the 1950s, the EOD Badge is issued in three levels and is identical for all branches of service. Although each service has its own requirements the basic EOD badge is issued upon completion of explosive handling training and between 18-24 months of on-the-job field training. The Senior EOD Badge is issued after 3-5 years as an explosive ordnance specialist and the Master Explosive Ordnance Disposal Badge is issued after 7-15 years of service in a senior supervisory position.
The "crab", as it is commonly known, is the only joint service badge and can only be earned upon successful completion of the 52 week course at the Naval School of Explosive Ordnance Disposal located at Eglin Air Force Base, Florida.
The Wreath Symbolic of the achievements and laurels gained minimizing accident potentials through the ingenuity and devotion to duty of its members. It is in memory of those EOD personnel who gave their lives while performing EOD duties.
The Bomb Copied from the design of the World War II Bomb Disposal Badge, the bomb represents the historic and major objective of the EOD attack, the unexploded bomb. The three fins represent the major areas of nuclear, conventional and chemical/biological interest.
Lightning Bolts Symbolize the potential destructive power of the bomb and the courage and professionalism of EOD personnel in their endeavors to reduce hazards as well as to render explosive ordnance harmless.
The Shield Represents the EOD mission -- to protect personnel and property.
As of 1 June 2006 for E6-E9 and 1 October 2006 for E1-E5, U.S. Navy EOD Technicians have become their own rating within the Navy. Only after being qualified as a Senior EOD Technician, is the technician designated as an EOD Warfare Specialist. An example would be: Petty Officer First Class Bob Jones, who is a Senior EOD Technician, would have his title read EOD1(EWS) Bob Jones.
