A soldier was on FOX today -- an ex-Iraq Vet -- who has invented a lightweight, but very strong helmet and face shield, he is trying to find someone to manufacture it (I think he finally found someone) and get the military to buy it for the soldier to help protect them from shrapnel. It was a very unique looking unit and the whole thing weighs less than a pound.
If you find any links to details on the helmut , you should post them.
