Wired For War: The Rise of Robotic Armies

What happens when science fiction becomes battlefield reality?
An amazing revolution is taking place on the battlefield, starting to change not just how wars are fought, but also the politics, economics, laws, and ethics that surround war itself. This upheaval is already afoot -- remote-controlled drones take out terrorists in Afghanistan, while the number of unmanned systems on the ground in Iraq has gone from zero to 12,000 over the last five years.  But it is only the start. Military officers quietly acknowledge that new prototypes will soon make human fighter pilots obsolete, while the Pentagon researches tiny robots the size of flies to carry out reconnaissance work now handled by elite Special Forces troops.
