Active Denial System Error 1.0 (2009)
Active Denial System Error 1.0 is a variation of the Active Denial System, a subtle weapon used for protection/surveillance of civil populations. ADS disables its targets with directed ultrasound rays, which penetrate into the nerve endings under the skin and cause a strong burning pain. When the ray changes direction, the pain immediately disappears. The American army industry advertises ADS as an ethical weapon.
