Being shot at and never knowing where it comes from is a sure sign of a sniper. So BBN has come up with a solution. It’s called the Boomerang Mobile Shooter Detection System and alerts soldiers of incoming sniper fire to give them the opportunity to retreat to safety. Using seven microphones to detect both the muzzle blast and the shock wave from a speeding bullet. Once a sniper’s bullet is detected, it alerts soldiers through audio and visual signals that a bullet has been fired its direction and elevation.Snipers are going to get extra sneaky with this system !
