The Challenger 2 is a heavily armoured and well protected tank.<ref name="Fprado">{{cite web |url=http://www.fprado.com/armorsite/chall2.htm |title=Main Battle Tank: Challenger 2 |publisher=Fprado.com |access-date=16 January 2011 |archive-url=https://web.archive.org/web/20070522041934/http://www.fprado.com/armorsite/chall2.htm |archive-date=22 May 2007 |url-status=live}}</ref> The turret and hull are protected by second-generation [[Chobham armour]], also known as Dorchester, the details of which are classified but which is said to have a mass efficiency more than twice that of [[rolled homogeneous armour]] against [[high-explosive anti-tank]] (HEAT) projectiles. Crew safety was paramount in the design. It uses a [[Solid-state electronics|solid state electric drive]] for turret and gun motion, instead of hydraulic systems that can leak fluid into the crew compartment.

[[Explosive reactive armour]] kits and additional [[bar armour]] may be fitted as needed. The nuclear, biological, and chemical (NBC) protection system is located in the turret bustle. The tank's shape is designed to minimise its radar signature. On each side of the turret are five L8 [[smoke grenade]] dischargers. The Challenger 2 can create smoke by injecting diesel fuel into the exhaust manifolds.
