Been readin U.S Military have developed a RAY GUN," flash flaa aash saviour of the universe" It reaches temperatures of 130f/54c,so its not painful,it just make you a bit uncomfortable!Its alright it is totally harmless,however it will make you drop your weapon ,if you have one.When the target is fired upon it makes them feel as though they are about to catch fire (flesh,not clothes).Doesnt actually kill anyone so it would be good in theatres like Iraq and Afganistan etc.
It uses milliwaves

and will be in production in2010.
The Military declined to answer if it goes through glass
Its an eye opener,but not surprising-where do we go to next?
