The XM-25 grenade launcher is equipped with a laser rangefinder and on-board computer. It packs a magazine of four 25mm projectiles, and programs them to detonate as they pass by their targets. That feature will allow soldiers to strike enemies who are taking cover. By 2012, the Army hopes to arm every infantry squad and Special Forces unit with at least one of the big guns.
In August, a lucky soldier got to pull the trigger, and fire off a HEAB, or High Explosive Air Burst, round at the Aberdeen Testing Ground in Maryland. Those projectiles pack quite a punch. They are purportedly 300 percent more effective than normal ammo, and will be able to strike targets as far as 700 meters (2,300 feet) away.
