Mobile Headquarters

Built on a halftrack chassis, the mobile headquarters was a vehicle designed specifically to provide battle control for military commanders as a moving command center, used during the First Tiberium War. Equipped with high-tech communications equipment, it allowed commanders to lead their troops effectively. Their appearance was identical to the radar jammer and the prototype Tesla tank in Red Alert.

In-game
The unit appears in the Capture the Flag (CTF) multiplayer mode of Command & Conquer when bases are disabled.

Normal CTF games spawn the players' MCVs with a flag attached, which is placed next to the construction yard on a flag pedestal when the MCV is deployed. When a player manages to steal the flag from its pedestal and bring it to their own, the 'resign' function triggers for the player whose flag was captured, causing all their units and structures to explode.

The mobile HQ compensates for the lack of fixed base positions to steal/capture flags in no-base games; its destruction triggers the 'resign' function for the owning player, again causing their immediate destruction.

Trivia

 * Mobile headquarters are sometimes used in the inner workings of fan-missions to cause specific units or structures to explode, because the original C&C lacks advanced trigger systems to cause such things. Often, these things are owned by non-standard houses (Special, Neutral, Multi1-Multi6) to appear as GDI or Nod materiel.
 * While the unit can not be produced, it can be sold for $300 on a repair bay.
 * It has a cameo in the original DOS version within the game's files, but not in the Windows-native Gold release, nor in Command & Conquer: Remastered. However, the unit appears in an unused cutscene, and there is a 640&times;480 render of the unit in that scene. This image was also the basis of the Radar Jammer cameo in Red Alert 1.
