The ammunition available to the Centurion Action X offers a wide range of projectiles to engage most types of targets:

  • Shot Mk.1: APCBC; an armour-piercing capped shell with ballistic cap that has a good penetration power but a rather average post-penetration damage effect. Make sure to target modules and crew positions to maximize the damage inflicted.
  • Shot Mk.3: APDS; an armour-piercing discarding sabot shot that has a very high penetration power but a poor post-penetration damage effect. Make sure to target modules and crew positions to maximize the damage inflicted.
  • Shell Mk.1: HE; a shell useful for destroying open and lightly armoured vehicles but whch travels at a slow speed.
  • 20pdr Shell SS Mk.1: Smoke; useful to blind enemy vehicles that are too remote for you to disable so that you can progress towards objectives. However, it is a very slow shell.

  • Shells are modeled individually and disappear from the rack after having been loaded in the breech.
  • Racks 8 and 9 are first stage ammo racks. They total 8 shells and get filled first when loading up the tank.
  • These 2 racks are also emptied first when firing: the rack depletion order at full capacity is: 9 - 8 - 1 - 2 - 3 until 7.
  • If you pack 29 (+36) shells, the rack depletion order will be 9 - 8 - 7.

The small calibre of the L3A1 machine gun makes it largely ineffective against all armoured vehicles but the ones with an open compartment. It still can be used to ping targets as a rangefinding help or to mow down minor obstacles blocking your line of sight.

Usage in 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 instead 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 and cons


  • Powerful and high penetrating 20 pdr gun, available with an APDS choice like other Centurions with 20 pdrs
  • Very quick reload time, down to 6.3 seconds per round when in full crew and ace experience
  • Have good gun depression and other traits like other Centurion
  • Good turret armour, up to 240 mm+ thick in some areas
  • Great RP and SL grinder like its Swedish cousin
  • With gun stabilizer


  • With only 39 (AB), 35 (RB and SB) km/h top speed, its mobility is mediocre when compared to some contemporary mediums
  • Ammo rack in the front (will be empty if 33 rounds are loaded) like other Centurions
  • Small internal compartment (only 4 crew members), easy to one-shot like its siblings
  • Although APDS provide high penetration even in long distances, it provides only punctual damage (Aim carefully)
  • Turret armour is not reliable sometimes due to some lower parts of turret armour is thinner (serious damages would occur if enemies penetrate it)
  • No explosive filler on any AP shells like other centurions in Rank IV



Development of the Centurion Action X began in the early 1950s. The aim of the project was to improve the Centurion's ballistic protection by fitting the vehicle with the recently developed 'mantletless' turret design. The turret was fitted on a Centurion Mk.7 hull and featured thick, heavily sloped surfaces which further increased its effectiveness.

Furthermore, the vehicle was tested with both the QF 20-pdr as well as the 105mm L7 cannon. In the end however, only a couple prototypes were built and tested in addition to a few turrets being used separately for ballistic trials. The Centurion Action X never passed the testing stage and was thus also not ordered into production. However, the experience gained during its development, specifically regarding the use of the mantletless turret, was later incorporated into subsequent tank designs such as the FV4202 and the well-known Chieftain main battle tank.
