Killer Robot Sentry

There are now more than 4,000 U.S. military robots on the ground in Iraq and Afghanistan. That number does not include thousands of unmanned aircraft that have clocked hundreds of thousands of flight hours.

The combat robots fitted with large-calibre machine guns deployed to Iraq for sentry duty, proved so successful that many more are on order. They have multiple eyes for 360 degree vision, night vision, zoom lenses, motion sensors, vid and audio capture, automated targeting, vast amounts of armor piercing ammo,

Up to now, a human hand has always been required to push the button or pull the trigger. Military leaders "are quite clear that they want autonomous robots as soon as possible, because they are more cost-effective and give a risk-free war." The units are actually inexpensive. They never get tired, hungover or bored.

Several countries, led by the United States, have already invested heavily in robot warriors developed for use on the battlefield.
