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Challenger 1 is a British main battle tank (MBT) used by the British Army from 1983 to the mid-1990s, when it was superseded by the Challenger 2.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.
Challenger Tractor The Challenger Tractor was the world's first rubber tracked agriculture tractor, created by Caterpillar Inc. in 1986. The original model was a Challenger 65 featuring the Mobile-Trac System (MTS) consisting of rubber tracks and a suspension system. The MTS combined the flotation and traction of steel tracks with the versatility of rubber tires. The use of tracks gave the machines increased tractive performance compared to traditional four wheel drive tractors equipped with tires. The Challenger 65 began as a 270 gross HP machine used primarily for heavy tillage.
