Challenger II Tank

The British FV4034 Challenger II is an advanced main battle tank currently in service with the armies of the United Kingdom and Oman. Built by the British company Alvis Vickers. The manufacturer claims that it is the world's most reliable main battle tank. Challenger II is a complete redesign from Challenger I, the MBT from which it was developed. Fewer than 5% of components are interchangeable, and the interior is reportedly totally different.
