General info
Survivability and armour
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 (Commander Independent Thermal Viewer)
- Dorchester 2F only marginally increases LFP armour against FIN shells and ATGMs
- Dorchester 2F adds 1,100 kg of weight to an already sluggish tank
- L27A1 has low penetration compared to other top rank NATO ammunition
- Accessible weakspots, especially the gun mantlet
History
The Challenger 2F or CR2 TES is an upgraded version of the Challenger 2, featuring the upgrade kit known as TES (Theatre Entry Standard) and nicknamed 'Megatron'. The upgrade protection kit saw several adjustments over the years until the present time.
These modifications were ordered by the MOD, as part of the numerous updates inside the Challenger 2's LEP (Life Extension Programme) to increase the operability, lethality and protection of the 1998 design until 2025, or until a new British MBT design is available. The TES aims to increase the protection levels against the operational threats of the British Army such as the IEDs, hollow charges or Tandem charges - common threats during suburban deployments.
MCS
The Challenger 2 was covered with an MCS (Mobile Camouflage System) all around the tank, reducing the heat signature and keeping the vehicle almost indistinguishable from Thermal imaging devices.
Bar armour
The slat or bar armour was added to the sides and the rear of the vehicle to increase the levels of protection against rocket-propelled grenades while not downgrading the mobility of the Challenger. The bar armour must disrupt any hollow charges from detonating; either by crushing it upon impact or damaging the warhead and the fuze through contact with the bars.
Dorchester 2F armour kit
Most previous NERA (Non-Explosive Reactive Armour) side plates have been reinforced with additional Dorchester armour plates, notably the lower frontal-glacis protection was drastically improved, with the addition of a large block of Dorchester armour; augmenting the protection in one of the most vulnerable areas for the Challenger 2. Furthermore, the sides of the turret also received external Dorchester armour packages, enhancing the protection of the crew inside the fighting compartment from possible side-attacks.
Remote controlled weapon systems (RCWS)
As an offensive upgrade, the TES received a new Remote controlled weapon systems (RCWS) over the loader's hatch ring, capable of assessing the battlefield and engaging light targets or infantry from within the vehicle. Previously, the operator had to open the hatch to fire the pintle-mounted L37A2 7.62mm GPMG machine gun.
The CR2 TES also received IED jammers near the left and right front fenders and ECM countermeasures antennas capable of detecting nearby Improvised Explosive Devices.
