US Army tests TrackingPoint smart-rifle scopesThe US Army is testing a "smart rifle" technology designed to improve the accuracy of shots.A spokeswoman confirmed reports that its equipment-testing specialists had acquired six TrackingPoint rifles as part of efforts to identify state-of-the-art equipment.The tech allows the user to place a virtual tag on a target seen through the weapon's scope.If the trigger is pressed, it only fires if the gun is correctly lined up.This prevents errors such as trigger jerk, range miscalculation and accidental firing from being a problem.
