In the heat of battle I imagine things can get pretty hectic and pinpointing just where the shooting is coming from, as quickly as possible, could mean the difference between life and death. To give its soldiers an edge in this regard the U.S. Army will begin providing its forces in Afghanistan with the first of 13,000 gunshot detection systems later this month. The Individual Gunshot Detector (IGD) uses the sound waves generated by enemy gunfire to instantaneously determine the location and distance toward the enemy fire.
The IGD, which is made by QinetiQ North America, consists of four small acoustic sensors contained in a box that sits on the soldier's shoulder, which is attached to a small display screen attached to the body armor that displays the distance and direction of incoming fire. The entire system weighs less than two pounds (0.9 kg).
Over the next 12 months, the Army plans to deliver up to 1,500 IGD's to its soldiers per month, with the plan to strategically disperse the systems throughout small, dismounted units to get maximum protective coverage for platoons, squads and other units on the move.
Hmm QinetiQ, why does that name ring a bell...
