Mao man jud na bambi, thats the only reason why the military doesnt mandate the use of kevlar for all troops; most troops prefer not to use it because of the weight; di pood mo help kai init kastanan man sa iraq.
The US Army already invented this:

In an effort to protect soldiers faces from flying derbis in war zones, a company called MTek has been testing a product called Predator Facial Armor. Because of the increased risk of airborne fragmentation threats, resulting from improvised explosive devices, also known as IED’s, MTek has produced the Predator Facial Armor System Technology, or FAST for short. The FAST G1, was designed for use by vehicle mounted personnel, more specifically crew served weapons operators.
