The U.S. Department of Defense is developing a device that enables the ground controller, who usually talks pilots down to the location of a ground target, to take control of sensors (cameras and ground radars) and weapons on UAVs, or even manned aircraft, and pull the trigger himself. Developing this gear (PCAS, or Precision Close Air Support) is actually not a major undertaking, because some of it already exists.
I guess my notion of doing this on ground vehicles wasn't as imaginative as I thought.
