Directed Energy Weapons <--clicky
The Zeus is actually a solid-state laser developed by the Army to heat up mines, to be able to clear minefields at a distance. In fact, the Zeus was deployed to Afghanistan, and several hundred mines were cleared by the use of this tactical weapon. There is another one called the THEL, or the Tactical High Energy Laser, that was developed for the Army, and this laser had actually shot down Katyusha rockets in White Sands Missile Range, and after over 30 Katyusha rockets were shot down, they decided to see if they could also shoot down mortars and artillery shells, and they were successful on that.
Sounds pretty cool.
