cards. The Headquarters could be split into four parts: a helipad, a heavy equipment supply depot, a motor pool, and the command center. It was portrayed in the Marvel comic book as a "prefabricated" fortress in issue #24, "The Commander Escapes". A new version was released in 1992, that was much different from the original. It featured collapsible towers, electronic battle sounds, spring-loaded missile launchers, a removable bunker, a fuel station for vehicles, and a movable elevator. The entire headquarters could fold up, with a handle to carry the playset around. Mobile Command Center The Mobile Command Center, or MCC for short, was a three-level mobile fortress, which contained service, command and missile bays, and was armed with high-tech weaponry. It was first released in 1987, packaged with the Steam Roller action figure. Its appearance is that resembling a small building with near-featureless exterior and tank treads at the bottom. The huge size though, presents a problem in how it could be deployed outside of the United States. Its size and few defensive capabilities suggest just what its name indicates, as a mobile command post and not more than that.

The front of the vehicle is armed with computer-operated twin .50 caliber cannons, while the back is protected by a "Barrage" missile cannon. The diesel engine can run at 2000 kW and with 2700 hp. Despite its immense size, the MCC is quite mobile and maneuverable, given the right terrain. The huge body can open up, and set itself as a stationary open-air command post, complete with a control center, a prisoner holding cell and a service station for small assault vehicles. In the Marvel Comics G.I. Joe series, its first appearance was in issue #100 (hinted at in #99). It was used to disrupt Cobra Python Patrol forces that had arrived at G.I. Joe's desert HQ. It had been buried in the sand, and Joe forces drive Cobra towards it. The sand is shaken off and the Command center opens fire. Its weaponry damages a Cobra aircraft, which is then flown into the Command Center itself. A rear tread is destroyed with only minor cosmetic damage to the rest of the vehicle. Steam Roller professes admiration for the pilot's courage. He then heads
