Reports of an Anglo-American effort to develop a crude force field to protect trucks and APCs from rocket-propelled grenades.
RPGs and other “shape charge” munitions derive their destructive power from cones of copper embedded in their noses. When the warhead explodes, it crushes the cone, shooting out a jet of hot copper at 5,000 mph — instantly destroying anything short of a tank.
The electrical armor system, powered by the vehicle’s regular supply of electricity, stops the jets by zapping them with tens of thousands of amps of current. This vaporizes some of the deadly copper jets and reduces the rest to a relatively harmless mixture of melted and pulverized debris that disperses around the vehicle.
Sweet.
