Comment Shooter reveals his location and a defense (Score 1) 188
Put a bunch of laser light sensors into the armys jackets, helmets and pants that would detect a laser light sweeping the person targetted and then immediately respond by shooting the same color laser down toward the ground from the helmet to make the bullet have to guess what the real target is (a bunch of dots preferably). While doing that the direction and location of the shooter could be determined by the sensors so retaliation could be swift. Or in cartoon style just have the sensors automatically make a laser of the same frequence that was detected shine a bunch of dots on the ground and direct the bullet back to the source laser transmission to take out the shooter :).
