Raytheon sure loves its lasers, and it's proving so with the crowd-repelling Silent Guardian. The device, which is part of the Directed Energy Solutions program, is reportedly designed to be mounted onto a military vehicle where it can "throw a wave of agony nearly half a mile," penetrating enemy skin just 1/64th of an inch and not causing "visible, permanent injury." Essentially, the invisible beam has the ability to inflict "limitless, unbearable pain," which seems to stop just as soon as you're able to get out of the ray's path. According to its maker, the machine could be used in "various commercial and military applications including law enforcement, checkpoint security, facility protection, force protection and peacekeeping missions," and it's ready to calm the masses as we speak.
