US Military Deploys Personal Gunshot Detectors
RedEaredSlider writes "A new warfighting technology will soon be making its way to Afghanistan. US Army forces will be getting gunshot detection systems, which can tell where a shot was fired from. Approximately 13,000 gunshot detection systems will be given to individual footsoldiers later this month, according to the US Army. The system, called Individual Gunshot Detector, has four small acoustic sensors and a small display screen attached to the soldier's body armor that shows the distance and direction of incoming bullets. The sensors are each about the size of a deck of cards and can detect the supersonic sound waves generated by enemy gunfire. It alerts the soldier of the shot's direction in less than one second."
I imagine the primary use of this is that, if bullets start flying and you take cover, you will be able to figure out where to return fire (or send backup, etc.) without needing to pop your head out first.
That's more or less right. If the bullets are flying in large quantities it's generally not hard to figure out where they're coming from, but if you've got one or two snipers taking potshots at your platoon, it can be quite difficult to find them. In those cases, the traditional method for locating the shooter involves the section/squad commander yelling "charlie team, take a bound!". This seems much safer.
