|Mobile Repair Vehicle|
The mobile repair vehicle is a support vehicle in Tiberian Sun.
It is a success, allowing any Nod vehicles that survive a battle to be ready for another in minutes through the use of advanced robotic repair technology. The speed of repairs is so phenomenal that one can noticeably increase the survival time of any given vehicle. The Mobile Repair Vehicle is not seen after the Second Tiberium War End.
MRVs are, however, expensive, costing more than a Tick tank, or even an advanced artillery piece. It was also slow, poorly armored, and completely unarmed, so alone or without sufficient support, they could be quickly eliminated. Even with sufficient support, it was often necessary to hold repair vehicles behind the lines. Yet another drawback results from the combination of the MRV's poor passive AI and the need for constant micromanagement of the unit in order to derive optimal usefulness out of it; for instance, it will not remain in a fixed, hold-ground position soliciting repairs to main battle units at the "mouth" of a base, but will actively chase often trivially damaged units (such as Harvesters) in no real need of assistance, inefficiently attempting to heal them while they are in motion and wind up halfway across the map by the time the player notices they are missing from the position they were supposed to be repair-patrolling. It can be very distracting in the heat of a battle when the player's attention is focused on a discrete group of units to find the MRV missing at the time it is needed most. Additionally, simply deploying MRV's to a location and putting them in guard mode will not prevent them from failing to discriminate between active battle units in dire need of repair and Harvesters in safe territory. MRV's also cannot be efficiently hotkeyed to one numeral as the ones being used to repair ground vehicles and the ones being used to repair aircraft would be employed in vastly different roles.
Overall, the GDI Service Depot with its ability to allow units to be queued in groups to it, coupled with the ability to create pseudo-rally points to it from front lines with waypoints, offers a vastly more efficient repair platform, an advantage which is never fully abrogated by the MRV's mobility, as the micro and AI issues are just too much of a handicap.
