The FV4201 Chieftain was the main battle tank (MBT) of the United Kingdom from the 1960s into 1990s. When introduced, it was among the most heavily armed MBTs of the era, mounting a 120 mm Royal Ordnance L11 gun, the equal of the much larger specialist heavy tanks then in service. It also was among the most heavily armoured, with up to 195 mm (7.7 in) that was highly sloped to offer 388 mm (15.3 in) thickness along the line of sight.

The Centurion was the primary British Army main battle tank of the post-World War II period. Introduced in 1945, it is widely considered to be one of the most successful post-war tank designs, remaining in production into the 1960s, and seeing combat into the 1980s. The chassis was adapted for several other roles, and these variants have remained in service. It was a very popular tank with good armour, mobility, and a powerful main armament.
