Usage in the battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros:

  • Decent front armour thickness.
  • Quite fast.
  • Hull machine gun works.

  • Very slow reverse.
  • Shells have no HE filler.
  • Weak side armour.

History

Prompt

The early combat experience of the Churchill infantry tank raised concerns on its reliability and speed, with a suggestion that production be halted while development focus on an "universal tank" for the British armoured forces to replace the cruiser and infantry tanks. However, until such a design could be formulated, they still needed a tank for the assault role the infantry tanks would take.

Rolls-Royce Company, the company producing the prototype A27 Cromwells, suggested that the Tank Board use the A27 as an interim design with stronger armour, suspension, and armament. The suggestion was supported with the English Electric Company, whom plan to upgrade the A27 with thicker armour and elements from the American M6 heavy tank.

Development and Cancellation

On 07 May 1942[1], Tank Board approved for the production of these uparmoured A27 under the designation A33, though it would also have the name Excelsior. English Electric Company were in charge of producing the uparmoured A27 models and produced two prototypes. The first had the M6 suspension system and a 6-pdr cannon. The second had a wider track, different armoured skirts, additional frontal armour, and a 75 mm gun. Both used the same V12 Meteor engine as the A27.

Reliability issues with the Churchill were soon ironed out by 1943, to the point it became a very successful infantry support vehicle and multiple variations were made based off the chassis. The A33 Excelsior, meant to replace the Churchill, was no longer needed and the project was dropped in 1943.

Today, the second prototype can be seen at the Bovington Tank Museum.
