Fricken FAST (Future Assault Shell Technology) helmet in my book is another waste of money of our Tax dollars. Funny thing is that these "operator" helmets started out back in the late 70s and early 80s as nothing more than OD/Camouflage painted Kevlar reinforced bicycle helmets for special purpose operators. Give me a well fitted MICH (Modular Integrated Communications)Helmet which offers better ballistic protection any day there "HighSpeed".
A butt load of Pogues who never operated tactically in a combat zone but claim expert experience status in the military contract world though they have never fired a shot in anger in most if not all cases, are going out of their way to buy fricken fast helmets at 2k a pop and they don't have the comms or other add ons for the thing, let alone a CSS and CS support element to make it effectual with real time digital HUD/return monitoring and IR/Thermal capability. That said, it must be nice to have a Cornucopia of special ops funds to waste on this shit if you have the optempo to get away with it.
