US Navy Surface / Submarine Warfare Badge Brass with gold Plate. It isn't a warfare badge, but rather an unofficial insignia of the Cryptologic direct support (DIRSUP) elements of the former Naval Security Group (NAVSECGRU), which was absorbed into Naval Net Warfare Command back in 2005. The device combines elements of the Naval Aircrew wings, the Surface Warfare Pin and the Submarine Warfare pin in recognition of the fact that NAVSECGRU DIRSUP personnel deployed on air, surface and subsurface platforms, and in particular, for many Naval personnel deployed on all three at various points in our careers. Also called FLISH badge. This badge is 2 3/4 inches wide.
