The drone deploys as a mine and waits for a target to pass over. The drone spot-welds itself to the underside of the target. Once attached the drone interferes with the electrical systems, usually resulting in a loss of speed, and relays terrain and tactical data back to its controller or designated radar facility from its sensor/camera device.
Sensor systems can detect deployed drones, and the drones can be disabled by an EMP. Field repair units were modified to remove drones from affected vehicles.
GDI developed the limpet drone prior to the Firestorm Crisis as another method of detecting stealthed Nod bases. They were fielded by covert operations teams before being released for general use. Nod also procured the technology and used it during the Firestorm Crisis as well.
Drones are hover units and may move over water. When deployed they become stealthed but can be instantly destroyed by EMP. A drone may be removed from an affected vehicle by having the vehicle repaired at a service depot or by a mobile repair vehicle; the drone is subsequently removed from play.
The fairly expensive cost ($550), high tier for a scouting unit (Radar, tier 2) and the fact it could be removed by any unit that can repair means this unit was all but useless unless the game was set to have fog of war (In which case it was used something like 1 in every 10 games.)
