Like the Chieftain Mk 10, the Challenger has a very strong turret front, with composite armour protecting the entire front and part of the sides. The turret front can resist up to 470 mm of rolled homogeneous armour equivalency (RHAe) against long-rod kinetic (~550 mm RHAe against rounds without the long-rod slope modifier) and up to 600 mm against chemical penetrators. This theoretically makes the strongest part of the turret frontally invulnerable to all but the top-rank kinetic ammunition in the game. In practice, however, there is a weak spot on the lower leading edge of the turret front, where the backing plate of the composite inside the turret flattens to a 90° angle. This reduces the effective thickness of the lower turret cheeks by approximately 100 mm, making it vulnerable to most long-rod APFSDS. A small portion of the turret front, the area just around the gun, is unprotected by composite armour and is 200 mm of CHA with a 50 mm RHA spall liner. This area extends above the gun and transitions to 60 mm CHA at 60°. While these areas are small and unlikely to lead to catastrophic damage when hit (the gun breech will tend to soak up shrapnel), they are important to be wary of.
 +
 
 +
The Challenger's turret sides are similar to many top-rank MBTs - they can only resist enemy fire at relatively high angles of attack. Protection is 140 mm RHAe against kinetic and 300 mm RHAe against chemical shells, meaning that the armour can only resist autocannon fire and low-calibre HEAT when struck dead-on.

Compared its turret, the Challenger hull is significantly weaker against kinetic projectiles with only 220 mm of RHAe (~300 mm for projectiles without the long-rod slope modifier) on the UFP. Chemical protection in this area is similar to the turret at 600 mm RHAe. An exception to these numbers is the area directly above the driver's hatch, which is not covered by composite armour and is vulnerable to essentially any anti-tank ammunition. The lower frontal plate is also lacking composite and is comprised of a single 70 mm RHA plate at a slight angle, providing ~80-90 mm of effective thickness. Shots to the LFP will at least incapacitate the driver, or more likely catastrophically detonate the hull ammunition. British tankers should be quite used to this weak spot by this point, as the weak LFP is present on the entire Chieftain line. However, the upper third of the LFP shares some of the UFP's composite protection due to its design. This means that the upper third of the LFP has slightly more protection than the lower sections.

Like the Chieftain Mk.10, the Challenger has a very strong turret, with composite armour protecting the entire front and part of the sides. Frontally, the turret can protect against, at maximum, 470 mm of kinetic (APFSDS, APDS, AP, etc.) and 750 mm of chemical (HEAT, ATGM, etc.) penetrators. This makes the turret theoretically invulnerable to most ammo in the game from enemies it can face, excluding the HOT missile on the [[RakJPz 2 (HOT)|Raketenjagdpanzer 2 HOT]]. In practice, however, there is a weak spot on the lower leading edge of the turret front, where the backing plate of the composite inside the turret flattens to a 90° angle. This reduces the effective thickness of the lower turret cheeks by approximately 100 mm when the tank is level (making it vulnerable to most long-rod APFSDS).

The Challenger hull is significantly weaker, with only 220 mm of RHA (~300 mm for projectiles without the long-rod slope modifier) for kinetic and 600 mm RHA for chemical penetrators on the upper frontal plate. An exception is the area directly above the driver's hatch, which is not covered by composite armour and is vulnerable to essentially any anti-tank ammunition. The lower frontal plate is also (mostly) lacking composite and is comprised of a single 70 mm RHA plate at a shallow angle, providing ~80-90 mm of effective thickness. Shots to the LFP will at best only incapacitate the driver, or more likely catastrophically detonate the hull ammunition. British tankers should be quite used to this weakspot by this point, as the weak LFP is present on the entire Chieftain line. However, the upper quarter of the LFP shares some of the UFP's composite protection due to its design. This means that the upper LFP has slightly more protection that the lower LFP.
+
Hull sides are generally very weak, as is typical of top-rank MBTs. The upper hull (above the tracks) is comprised of a 20 mm RHA + fuel tanks + 25 mm RHA array. The lower hull (around the tracks) is comprised of 19 mm aluminium side skirts and 34 mm RHA.

The Challenger's speed sets it apart from the previous Chieftain tanks, as it is capable of reaching 56 km/h on roads and 46 km/h off-road. Reverse speed is also a noticeable improvement from the Chieftain line. Despite this, the 62 ton mass of this vehicle makes it the slowest of its high-rank contemporaries (e.g. Abrams, Leopard, and Type 90).

The FPE module should be a priority, since the fuel tanks are located all around the hull above the tracks, meaning that the tank will be set on fire often. This comes with added protection, however, as the fuel tanks will frequently absorb most shrapnel - protecting the crew and ammunition from the occasional side-shot - giving the player ample time to return fire and eliminate the threat.

The Challenger bears the 120 mm L11A5, an updated but essentially identical version of the gun found on the Chieftains. It has access to the same rounds as the Chieftain Mk 10, with the notable addition of the L23A1 APFSDS ammunition. Despite having worse flat plate penetration (24 mm less than L23 at 1 km), L23A1 penetrates angled armor much more efficiently than its predecessor (29 mm more than L23 at 1 km at 60°), making it especially useful for dealing with Russian late T-series hulls.

New drivers of the Challenger 1 will appreciate a similar play style to the earlier Chieftain tanks, particularly the [[Chieftain Mk 10]]. Most of the armour's weakpoints could be minimized by assuming a hull-down position on the incline of a hill, and using the Challenger's excellent -10° of gun depression to keep the gun on target. This will increase the angle of the turret and thus increase the effective thickness of the back-plate on the turret.

In 1977, the Iranian government ordered an improved version of the Chieftain tank, which was arguably the best main battle tank (MBT) in service at its time. The Chieftain offered unparalleled protection and firepower; however, its mobility was lackluster and something its successor needed to improve upon. In response, the engineers at the MVEE created the Chieftain Mk.5(P), from which three additional prototypes were created. It was one of these prototypes that would become the basis for the Challenger 1. Unfortunately, after the Iranian Revolution of 1979 and the fall of the Shah, Iran canceled its order for an improved Chieftain. In addition, a parallel British tank project (the MBT90) was also abandoned, and the British Army quickly became a new potential customer for a new MBT.

The Challenger's design was based on the cancelled project called "Shir-2”" planned for export to Iran, and retained its deadly 120mm gun and superb armour. The Challenger was also equipped with Chobham armour, a composite armour made from multiple layers of different materials. The additional materials gave the Challenger its distinctive, heavily-sloped armour on the front of the turret and upper glacis. The Challenger’s mobility and off-road capabilities were significantly improved with the installation of a new 1,200 horsepower Rolls-Royce engine and hydropneumatic suspension. The Challenger 1 entered production and service in 1983. Production ended in 1990, having yielded a total of about 420 vehicles. It served primarily with British forces during the Gulf War. It was also used in peacekeeping missions in Bosnia-Herzegovina during the mid 1990s, and Jordan still operates a number of Challenger 1 tanks to this day. The Challenger 1 was withdrawn from active service by 2001 and later replaced by the Challenger 2.

Description

The Tank, Combat, 120-mm Gun, Challenger Mk.2, or just Challenger Mk.2, is a rank VII British medium tank with a battle rating of 10.3 (AB/RB/SB). It was introduced in Update 1.77 "Advancing Storm".

Like the Chieftain Mk 10, the Challenger has a very strong turret front, with composite armour protecting the entire front and part of the sides. The turret front can resist up to 470 mm of rolled homogeneous armour equivalency (RHAe) against long-rod kinetic (~550 mm RHAe against rounds without the long-rod slope modifier) and up to 600 mm against chemical penetrators. This theoretically makes the strongest part of the turret frontally invulnerable to all but the top-rank kinetic ammunition in the game. In practice, however, there is a weak spot on the lower leading edge of the turret front, where the backing plate of the composite inside the turret flattens to a 90° angle. This reduces the effective thickness of the lower turret cheeks by approximately 100 mm, making it vulnerable to most long-rod APFSDS. A small portion of the turret front, the area just around the gun, is unprotected by composite armour and is 200 mm of CHA with a 50 mm RHA spall liner. This area extends above the gun and transitions to 60 mm CHA at 60°. While these areas are small and unlikely to lead to catastrophic damage when hit (the gun breech will tend to soak up shrapnel), they are important to be wary of.

The Challenger's turret sides are similar to many top-rank MBTs - they can only resist enemy fire at relatively high angles of attack. Protection is 140 mm RHAe against kinetic and 300 mm RHAe against chemical shells, meaning that the armour can only resist autocannon fire and low-calibre HEAT when struck dead-on.

Compared its turret, the Challenger hull is significantly weaker against kinetic projectiles with only 220 mm of RHAe (~300 mm for projectiles without the long-rod slope modifier) on the UFP. Chemical protection in this area is similar to the turret at 600 mm RHAe. An exception to these numbers is the area directly above the driver's hatch, which is not covered by composite armour and is vulnerable to essentially any anti-tank ammunition. The lower frontal plate is also lacking composite and is comprised of a single 70 mm RHA plate at a slight angle, providing ~80-90 mm of effective thickness. Shots to the LFP will at least incapacitate the driver, or more likely catastrophically detonate the hull ammunition. British tankers should be quite used to this weak spot by this point, as the weak LFP is present on the entire Chieftain line. However, the upper third of the LFP shares some of the UFP's composite protection due to its design. This means that the upper third of the LFP has slightly more protection than the lower sections.

Hull sides are generally very weak, as is typical of top-rank MBTs. The upper hull (above the tracks) is comprised of a 20 mm RHA + fuel tanks + 25 mm RHA array. The lower hull (around the tracks) is comprised of 19 mm aluminium side skirts and 34 mm RHA.

Armour type:

  • Composite armour (hull UFP, turret front and sides)
  • Rolled homogeneous armour (hull)
  • Cast homogeneous armour (gun "mantlet")

Notes:

  • Suspension wheels, torsion bars, and tracks are 20 mm thick.
  • Turret ring is 60 mm thick.
  • 20-25 mm RHA plates surround the fuel tanks on the hull sides.
  • Hull composite armour configuration is 50 mm RHA + 200 mm NERA elements + 80 mm RHA.
  • Front turret composite armour configuration is 50 mm RHA + 600 mm NERA elements + 110 mm RHA.
  • Turret side composite armour configuration is 25 mm RHA + 300 mm NERA elements + 80 mm RHA.

The Challenger Mk.2's speed sets it apart from the previous Chieftain tanks, as it is capable of reaching 56 km/h on roads and 46 km/h off-road. Reverse speed is also a noticeable improvement from the Chieftain line. Despite this, the 62 ton mass of this vehicle makes it the slowest of its high-rank contemporaries (e.g. Abrams, Leopard, and Type 90).

The Challenger bears the 120 mm L11A5, an updated but essentially identical version of the gun found on the Chieftains. It has access to the same rounds as the Chieftain Mk 10, with the notable addition of the L23A1 APFSDS ammunition. Despite having worse flat plate penetration (24 mm less than L23 at 1 km), L23A1 penetrates angled armor much more efficiently than its predecessor (29 mm more than L23 at 1 km at 60°), making it especially useful for dealing with Russian late T-series hulls.

Usage in battles

New drivers of the Challenger 1 will appreciate a similar playstyle to the earlier Chieftain tanks, particularly the Chieftain Mk 10. Most of the armour's weak points could be minimized by assuming a hull-down position on the incline of a hill, and using the Challenger's excellent -10° of gun depression to keep the gun on target. This will increase the angle of the turret and thus increase the effective thickness of the back-plate on the turret.

When encountering common enemies:

  • T-64B: L23A1 can theoretically penetrate the UFP, but it is very difficult. The drivers port weak spot is the recommended target from the front. If not possible, aim for the breech/cannon barrel to eliminate the threat of returning fire.
  • T-64A (1971): L23 will go right through the hull even at 2 km, but the Challenger can still be immobilized and disarmed if even 3BK12M (stock HEATFS) is fired at the breech, which will break the turret ring, the breech and possibly the engine.
  • Leopard 2K: Shoot anywhere honestly. Shooting its right cheek will knock out the gunner and TC. Shooting the UFP under its left cheek detonates the turret ammo storage. Shooting just left of the driver's port can even cause a total crew knock-out instantly, even with L23 at 1000 m. Just be aware that DM13 and DM23 will have no issues penetrating your hull either.
  • Leopard A1A1: Its APFSDS poses a risk to the weak spot on the turret, but only if it gets the first shot off. Shoot anywhere near hull centre or low turret area.

Pros and cons

Pros:

  • Good composite armour for both kinetic and chemical protection on hull and turret
  • Very accurate main gun with effective gun stabilizers, depression angles and decent stock APFSDS shell
  • Decent mobility for its weight and size: a drastic increase and from all previous British MBTs
  • Great hull down performance that multiplies armour efficiency, especially at long ranges
  • No stock HEATFS shells unlike most counterparts at the rank, easing the module research
  • One of the few MBTs that has access to a smoke shell for the main gun; with the auxiliary HESH against light armour
  • Reload can get down to 5 seconds, fastest firing 120 mm along with Type 90/Type 90 (B)

Cons:

  • Only 4 rounds of first-stage ammunition, then it can take up to 8.7 seconds to reload the gun until ready rack replenishes again
  • Large and tall target, with the accessible Driver's optics weak spot on the upper frontal plate and vulnerable hull armour
  • No external composite or reactive armour
  • HESH shell is generally useless against other MBTs
  • Ammunition and charges takes a lot of space (easy to hit)
  • Firepower, mobility or armour characteristic are outmatched by tanks as Leopard 2 (Family), Ariete (Family) or T-80 (Family)

History

In 1977, the Iranian government ordered an improved version of the Chieftain tank, which was arguably the best main battle tank (MBT) in service at its time. The Chieftain offered unparalleled protection and firepower; however, its mobility was lacklustre and something its successor needed to improve upon. In response, the engineers at the MVEE created the Chieftain Mk.5(P), from which three additional prototypes were created. It was one of these prototypes that would become the basis for the Challenger 1. Unfortunately, after the Iranian Revolution of 1979 and the fall of the Shah, Iran canceled its order for an improved Chieftain. In addition, a parallel British tank project (the MBT90) was also abandoned, and the British Army quickly became a new potential customer for a new MBT.

The Challenger's design was based on the cancelled project called "Shir-2"" planned for export to Iran, and retained its deadly 120 mm gun and superb armour. The Challenger was also equipped with Chobham armour, a composite armour made from multiple layers of different materials. The additional materials gave the Challenger its distinctive, heavily-sloped armour on the front of the turret and upper glacis. The Challenger's mobility and off-road capabilities were significantly improved with the installation of a new 1,200 horsepower Rolls-Royce engine and hydropneumatic suspension. The Challenger 1 entered production and service in 1983. Production ended in 1990, having yielded a total of about 420 vehicles. It served primarily with British forces during the Gulf War. It was also used in peacekeeping missions in Bosnia-Herzegovina during the mid 1990s, and Jordan still operates a number of Challenger 1 tanks to this day. The Challenger 1 was withdrawn from active service by 2001 and later replaced by the Challenger 2.
