WELL, THIS IS THE 21ST CENTURY, YOU KNOW: Military Snipers Could Soon Be Using ‘Guided’ Bullets. “EXACTO, or Extreme Accuracy Tasked Ordnance bullets turns .50 caliber bullets into guided rounds capable of zeroing in on a target. Although DARPA is mum on how it does this, other sites report that the technology involves optical sensors in the nose of the bullet and fins capable of adjusting the bullet’s flight path in the tail. The optical sensor apparently homes in on a spot illuminated by a laser designator. The guidance system is similar to laser-guided weapons such as the Maverick and Hellfire laser-guided missiles. The bullet is even capable of making some remarkably sharp course corrections.”
