(CBS) Every so often in the history of war, a new weapon comes along that fundamentally rewrites the rules of battle. This is a story about a revolution in unmanned aviation that is doing just that.
Most people know them as drones; the Air Force calls them "unmanned aerial vehicles." And right now, there are dozens of them in the skies over Iraq and Afghanistan, hunting down insurgents, every minute of every day.

Many of the details of this weapons program are classified, but our 60 Minutes team was given secret clearance and unprecedented access to bring you this story.
