The active denial system is a perfect nonlethal crowd control device - a high-powered energy beam that can disperse an unruly mob without killing, maiming, or harming anyone. Known officially as a “Vehicle-Mounted Active Denial System”, this new weapon is said to be more humane and more effective than other methods of controlling a large crowd or stopping aggressive intruders dead in their tracks.

Here’s how it works. A special transmitter fires two-second bursts of focused microwave energy that causes burning sensations on the skin of people up to 700 yards away. But no one gets fried and no telltale burn marks linger on the body because the beam only penetrates just beneath the skin’s surface at a depth of 1/64th of an inch. Targets of this concentrated electromagnetic pulse briefly experience intense pain and confusion, prompting them to leave the area in hurry.

美国研制的一种射束武器。，该武器以密集的射束发射高频电磁波，射束加热肉体中的水分，使被击中的人产生灼烧的感觉，主要用于控制骚乱与维和行动。
