Cool: New American "Smart" Grenade Launcher Deployed in Afghanistan

The Pentagon has rolled out prototypes of its first-ever programmable "smart" grenade launcher, a shoulder-fired weapon that uses microchipped ammunition to target and kill the enemy, even when the enemy is hidden behind walls or other cover.

The gun's stats are formidable: it fires 25mm air-bursting shells up to 2,300 feet (700 meters), well past the range of most rifles used by today's soldiers, and programs them to explode at a precise distance, allowing troops to neutralize insurgents hiding behind walls, rocks or trenches or inside buildings.
