The size and performance of the CRARRV are similar to a Challenger 1 tank, but instead of armament it is fitted with: In order to improve flexibility and supplement the transportation of power packs around the battlefield, the British Army procured a quantity of dedicated CRARRV High Mobility Trailers (HMT).

CRARRVs have subsequently been upgraded to use the updated Challenger 2 powertrain consisting of a CV12-5C/6C engine[2] with TN54E transmission.

There is room in the cabin for two further passengers (e.g. crew members of the casualty vehicle) on a temporary basis.

British CRARRVs were first deployed in action in the lead up to the First Gulf War, Operation Granby in 1991.

They were subsequently deployed alongside Challenger 2 tanks during the 2003 invasion of Iraq, Operation Telic in 2003.
