The K2 Black Panther (Korean New Main Battle Tank) is a modern MBT developed by Hyundai Rotem for the Republic of Korea Army (RoKA). The Perkins-Condor CV12 engine of the tank ensures a maximum on-road speed of 59km/h and off-road speed of 40km/h. The second-generation Chobham armour of the Challenger 2 offers a high-level of protection against direct fire weapons. The tank can carry 50 Armour Piercing, Fin Stabilised, Discarding Sabot (APFSDS), high-explosive squash heads (HESH) and Soke rounds, as well as 4,000 rounds of 7.62mm ammunition. The 120mm 元0 CHARM (CHallenger main ARMament) gun of the Challenger 2 provides primary firepower while a C-axial 7.62mm chain gun and a turret-mounted 7.62mm machine gun serve as secondary weapons. Promoted as the world’s most reliable main battle tank by its producers, the capabilities of Challenger 2 were proven during combat missions in Bosnia, Kosovo and Iraq.

The MBT was designed and manufactured by British Vickers Defence Systems (now BAE Systems) based on the Challenger 1 tank.

The Challenger 2 (CR2) is the main battle tank of the British Army and the Royal Army of Oman.
