Contains: 3x Centurion 3 or Centurion 1 Tanks

The introduction of the Centurion 1 gave British forces a heavily armoured medium tank with a gun that could defeat the armour of its contemporaries. Soon after, Royal Ordnance finished development of the new Ordnance QF 20 pdr (84 mm) gun and work quickly began on upgrading the Centurion.

The Mark 2 version of the Centurion had already upgraded the turret design, improved the crew systems to help them acquire targets and added stabilisation to improve accuracy whilst on the move. The co-axial 20mm Polsten cannon, that gave the earlier Centurion a unique look, was also removed and replaced with a more traditional Besa machine-gun.
