チョバムアーマーの第二世代の一部であって別物というのがそもそもの間違い
ERAも装甲の一部

The shape of the turret remains also the same,
but the overall protection was pushed even further with the 2e generation of Chobham armor called "Dorchester".

Of highly classified composition, it is alleged to offer the same penetration of the former armor but with double thickness equivalent to steel.
On top of that, provision for ERA bricks and slat (BAR) armor was also part of the new kit.
In short, the Challenger 2 offered probably the best level of passive armor worldwide in 1998.
Crew safety was also pushed forward, with a turret and gun solid state electric drive, which eliminated the hydraulic circuits.
