General information
The Chieftain Mk 3 is a British medium tank. It was introduced in Update 1.57 "Battle March" and established the series of end-game ground vehicle for the British tree. The Chieftain imposes a formidable force of reckoning on the battlefield with its heavily sloped armour and powerful 120 mm armament.
The Chieftain series maintains the traditional UK lower front plate weak spot and strong turret armour of the Centurion series of tanks while increasing the firepower. Top speed increases from the Centurion line, but overall mobility is comparably worse.
