What does the Challenger 2 have in common with the Challenger 1?
Challenger 1 The FV4030/4 Challenger 1 is a British main battle tank (MBT) used by the British Army from 1983 to the mid-1990s, when it was superseded by the Challenger 2. It is also currently used by the Royal Jordanian Army as its main battle tank after heavy modifications. The variants for the Jordanian military are to be upgraded using the unmanned Falcon turret.
BRP Can-Am Spyder Roadster The Can-Am Spyder ("Spyder") is a three-wheeled motorcycle manufactured by Bombardier Recreational Products. The vehicle has a single rear drive wheel and two wheels in front for steering, similar in layout to a modern snowmobile. The Spyder uses an ATV-like chassis. The manufacturer refers to it as a "roadster," but in technical terms it is more of what has been traditionally called a trike. The Spyder was officially launched in February 2007.
