The Bedford Cockatrice was ordered for the defence of the coastal bases of the Fleet Air Arm in the event of glider- or parachute-dropped invasion troops. It was estimated that such troops would need roughly one minute upon landing to detach themselves from their equipment and open fire, and so the Cockatrice was believed to be the ideal fast-response defence vehicle, able to kill or terrorise into surrender a force of the small size expected to be attacking such remote airfields. Sixty Cockatrice were built and served at Royal Navy Air Stations. The RAF received six Heavy Cockatrice for airfield defence. Three Oke-equipped Churchill tanks were used on the Dieppe Raid.
