Centurion Mk. 5/1 RAAC Pictures

Bonus: description of the tier 8 premium medium tank:

One of the modifications of the post-war British tank Centurion Mk. 5, had reinforced front armor, better armament and a more powerful engine. The distinguishing feature of the vehicle is an additional 100-gallon fuel tank, located at the rear of the tank and no armor screens. It was in the possession of Australian armored units during the Vietnam War.
