Prior to the Third Tiberium War, both GDI and Nod equipped their production structures with autonomous repair drones, which automatically repair any nearby vehicles. Scrin prduction structures are equipped with similar repair drones. In particular, their warp spheres have the ability to summon reconstruction drones, which Scrin foremen are trained to deploy whenever their forces require repair, even in the midst of combat.
Each production structure provides three repair drones, which gradually repair nearby damaged units, healing 150 HP at a time. Drones deployed by aircraft production facilities can only repair aircraft, and drones deployed by other means can only repair ground vehicles. Scrin drones are unique in that they can also heal wounded infantry.
Ground vehicle production structures can use the "Repair Vehicle" ability to order all of their drones to repair a single vehicle, speeding up the repair process somewhat. Aircraft production structures do not have this ability. In addition to production structures, the battle base also deploys three repair drones and the Mobile Repair Transport comes with one repair drone.
Drones cannot be attacked, but require power to function and will disappear if their parent structure has no power. Once power is restored, they will redeploy after some time.
