"New non-lethal energy weapon heats skin
By KELLY HEARN, UPI Technology Writer
WASHINGTON, Feb. 26 (UPI) – The Marine Corps is developing a non-lethal weapon that uses electromagnetic energy to heat but not permanently burn human skin. The weapon could help soldiers counter terrorism threats, control unruly crowds and defend airfields and ships. Experts confirmed it was the first time the military had designed a so-called “directed energy weapon” for use against human targets.
The weapon concentrates energy into a beam of micro-millimeter waves that penetrate clothes to rapidly heat moisture particles in the outermost layer of flesh without going deep enough to damage organs. The device reportedly
causes no permanent damage to the body or to electronic devices such as pacemakers.
Though detailed information about the weapon’s design remain classified, the story stated that the weapon would heat a target’s skin to approximately 130 degrees Fahrenheit in about two seconds. Humans start to feel pain at 113 degrees. The report went on to say that soldiers could fire the weapon from distances exceeding 750 meters (2,250 feet) from their target – a range that would allow them to remain outside the reach of most small arms fire. The weapon could be mounted atop a military vehicle or on an aircraft."
