Pentagon Loans Nonlethal Active Denial System To Homeland Security
The US Customs and Border Protection agency is evaluating the use of a heat ray developed by the Defense Department for crowd control purposes. The Active Denial System, which produces a reversible heating sensation to the skin, was loaned to the Department of Homeland Security by the Pentagon. The system has been tested by the Marine Corps and Air Force, and has been considered for use in various scenarios, including perimeter defense and area denial. The technology was first reported by Stars and Stripes.
