Coast Guard Flight Surgeon Insignia

The Flight Surgeon Badge is a military badge of the United States Armed Forces which has existed since the Second World War.
The Coast Guard Flight Surgeon Badge is the same pattern as the USCG Aviator badge, but with a caduceus superimposed over the central shield. Unlike USN and USN medical support of USMC, USCG Flight Surgeons are commissioned corps officers of the U.S. Public Health Service.
Coast Guard flight surgeons generally attend the Army course followed by a two-week USCG transition course.
