* Weapon hailed as a game-changer that can fire up and over barriers and down into trenches
* Soldiers will start using them in Afghanistan later this month
The U.S. army is to begin using a futuristic rifle that fires radio-controlled 'smart' bullets in Afghanistan for the first time, it has emerged.
The XM25 rifle uses bullets that be programmed to explode when they have travelled a set distance, allowing enemies to be targeted no matter where they are hiding.
The rifle also has a range of 2,300 feet making it possible to hit target which are well out of the reach of conventional rifles.
The XM25 is being developed specially for the U.S. army and will be deployed with troops from later this month, it was revealed today.
