A new weapon, a smart weapon has been deployed to front line troops in Afghanistan. The XM25 Grenade launcher has a range of a half mile and can the grenades can be set to explode in an airburst at distance up to a half mile. US deploys 'game-changer' weapon to Afghanistan - Yahoo! News This weapon can really change the face of small unit combat. To be able to reach behind barriers and terminate a threat helps in the ridges and valleys of Afghanistan. The enemy can no longer pop up and shoot and then duck back down and be safe.

Lets hope that other countries do not get this technology soon!
