he Challenger 2 main battle tank entered service in the British Army in 1994, although its development dates back to the 1980s. Since then, it has served in Yugoslavia, Eastern Europe, and Iraq in the Middle East, and not one model has ever been lost to enemy fire.Despite its impressive firepower and armor, the tank’s turret is outdated by modern standards, especially its rifled gun barrel.Consequently, almost 25 years after its introduction on the battlefield, the British Army has decided to replace it with an improved version, the Challenger 3.According to the military, this new model will become the most lethal tank in all of Europe.
