After years of work, Orbital ATK (born from Orbital Sciences) is close to delivering a clever weapon that could help American soldiers in very tricky situations. As of early 2016, the US Army will start acceptance testing for the XM25, a smart grenade launcher that can defeat enemies behind cover. In normal use, all you have to do is point at an enemy (up to 1,640 feet away) and let the XM25's laser rangefinder decide when your grenade explodes. If a target is hiding, however, you can dial in extra distance (up to 2,300 feet away) and explode the grenade in mid-air. Troops theoretically don't have to expose themselves to line up a shot -- they just pick a close-enough point and pull the trigger.
