"Tank, Cruiser, Challenger (A30)"@en . . "2.7432"^^ . "The Tank, Cruiser, Challenger (A30) was a British tank of World War II. It mounted the QF 17-pounder anti-tank gun on a chassis derived from the Cromwell tank to add heavier anti-tank firepower to the cruiser tank units.The design compromises made in fitting the large gun onto the Cromwell chassis resulted in a tank with a powerful weapon, but with less armour."@en .
