The Trojan armoured engineer vehicle is based on a Challenger 2 tank chassis, but lacks the main armament.

For rapid mine-clearing purposes, the Trojan can also tow a trailer carrying the Python, a rocket-propelled hose similar to the Giant Viper.

The hose, packed with explosive, is launched across a minefield, and detonates after it hits the ground, clearing a 7-metre wide path for 230 metres.

A number of Trojans are permanently based in Canada at British Army Training Unit Suffield in order to allow the Royal Engineers to support Armoured Battle Groups on major exercises.

[3] Its companion vehicle, developed at the same time, is another variant of the Challenger 2, the Titan armoured bridge layer, of which 33 have also been built.
