Challenger 2 (CR2) is the British Army's main mattle tank. CR2 is based on the Challenger 1 tank, which served with distinction on operations in the Gulf War and the Balkans.
Only five percent of Challenger 2 components are interchangeable with its predecessor, which has had more than 150 major modifications including a completely new turret, L30 CHARM 120mm gun and second generation Chobham armour.
Challenger 2's thermal observation and gunnery displays a magnified image for the commander and gunner. The commander has a gyro-stabilised fully panoramic sight with laser range finder and thermal imager.
The gunner is equipped with a gyro-stabilised primary sight with a laser range finder and coaxially mounted auxiliary sight. The driver's position has an image-intensifying day and night periscope, and the loader has a day sight.
