The Mobiles are tank-like all-terrain vehicles, at least four of which are known to exist, that S.H.A.D.O. uses for locating and dealing with UFOs that have landed on Earth. A typical Mobile can seat at least two persons up front and has a cargo area in the back. One of the Mobiles has a command post contained in its cargo area. They are armed with turret guns on the top, from which rockets can be launched as well, and they are transported to an approximate location by transport planes or trucks("lorries" in Great Britain).
