Non-lethal weapons are intended to have reversible effects on personnel and material. They provide soldiers with another option when lethal force isn’t considered to be the best first response to a situation. One non-lethal weapon prototype that is being evaluated by U.S. military is the Thermal Laser System, which attaches to a rifle and uses a laser to create a heating sensation to repel adversaries. Unfortunately, current trials indicate that clothing nullifies the weapon's effectiveness.
November 5, 2005 No this is not a movie prop nor will it be marketed by Mattel for the bigger boys this Christmas– it is one of two working prototypes of a non-lethal laser gun built by the Air Force Research Laboratory's Directed Energy Directorate. The non-lethal illumination technology weapon was developed by the laboratory's ScorpWorks team. Dubbed the PhaSR (who needs a Madison Avenue creative team when you can come up with names like this – an acronym for Personnel Halting and Stimulation Response), it is the first man-portable, non-lethal deterrent weapon and is intended for protecting troops and controlling hostile crowds. The weapon employs a two-wavelength laser system and is a hand-held, single-operator system for troop and perimeter defense. The weapon’s laser light temporarily blinds its targets.
