The Challenger 2 (2F) was created to give increased protection against shaped charges and as much is evident when evaluating the armour. While the internal composite armour remains the same from the previous variant, a large amount of external composite and ERA has been added to the hull front and sides as well as the turret sides. Additional slat armour has also been mounted to the sides and rear of the hull and turret.

With the only real change being the additional external armour, the same structural weakspots that exist on the Challenger 2 remain on the 2F. The large driver's port is an obvious target for enemy armour, which can penetrate it at almost any angle due to only RHA protection. Kinetic rounds aimed through the driver's port from the direct or near-direct front will often go straight through the tank, often taking several crew members, the cannon breach or the engine, occasionally resulting in a knocked out crew. Chemical rounds are less effective but fragments may set off the charges stored next to the driver, especially when fired at from above.

The gun mantlet is also a large weakspot, although kinetic rounds will be most effective, as chemical rounds will often only knock out the cannon breach or be blocked by the optics mounted at the top of the gun, which will allow the tank to pull back and repair provided it has the distance to do so. Kinetic rounds will often not fragment properly, going straight through the back of the turret, at max taking out two crew members due to the breach acting as a shield to the other side of the turret. Only when attacking from above will rounds have a significant chance of detonating ammunition due to the 2 stage system used by British tanks. Any ammunition stored in the turret will be warheads which are not able to be detonated.

As with the last variant and many other MBTs, the sides have no real kinetic protection, however the 2F has additional protection against chemical rounds. Most shots to the side of the front half of the turret have a high likelihood of taking out the cannon breach and a crew member, occasionally knocking out 2 or 3 crew. Any shots the the back half of the turret from the side will be ineffective due to the large amount of empty space. Aiming low on the tank's hull will give the best results for penetration and ammo detonation. Despite the additional ERA on the lower frontal plate, chemical rounds such as the German DM12A1 can still get through, and can get through the side mounted composite screens on a flat angle (0-25°).

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

Pros:

  • Effective side-ERA against air-to-ground missiles
  • Fast reload, particularly for a 120 mm (5 seconds aced)
  • Sights with high zoom, 2nd generation thermals and a wide FOV
  • High reverse of -40 km/h
  • The L30A1 120 mm gun is incredibly accurate, even at long range
  • Turret cheeks are invulnerable to all HEAT-FS and APFSDS, including the dreaded DM53 shell

Cons:

  • Vulnerable commander's hatch and cannon breech
  • No CITV
  • Dorchester 2F only marginally increases LFP armour
  • Dorchester 2F adds 1,100 kg of weight to an already sluggish tank
  • L27A1 has low penetration compared to other top rank NATO ammunition
  • Large weakspots, especially the mantlet

History

Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
