Description

The Challenger was introduced in 1983, as the new MBT for the British Army. While reliability and performance were debated during the Canadian Army Trophy of 1987, their action in Operation Desert Storm, also known as the Gulf War, gave them a chance to prove their worth. In this time, the British Army deployed the 1st Armoured Division in the Middle East with 3 Armoured Brigades equipped with Challenger tanks, some of which were the latest Mk.3 variant with new ERA installed. The Challengers had a good performance, dealing with several T-55s and Type 69s while not losing a single tank. A Challenger tank holds the record for the longest tank-to-tank kill, achieving a destruction at a range of 5.1 km in 1991.

It was introduced in Update "Danger Zone". The Challenger Mk.3 Desert Storm is identical to the Challenger Mk.3 found in the tech tree, the only difference is the visual discrepancy and the fact that it lacks ROMOR ERA in the sides of the vehicle. Compared to most Soviet and other NATO platforms, the Challenger is very heavy and quite slow; while it struggles to accelerate, it has a very good top speed and an excellent reverse speed. The cannon is a powerful 120 mm gun, with access to 1st generation thermals for the gunner, which means that it has a very competent armament for its BR.

Overall, the armour on the Challenger DS is exactly the same as the tech tree counterpart, the Challenger Mk.3. However, it lacks the additional ROMOR ERA and the sides armour package. It gets a slight but negligible upgrade on the lower frontal plate compared to the Challenger Mk.2 as it has spare tracks strapped on the LFP. While it is a Challenger Mk.3, it is most comparable to the Challenger Mk.2 in terms of armour. The upper half of the turret cheeks are capable of withstanding almost all kinetic penetrators and will stop most chemical projectiles with less than 800 mm penetration, while the lower half won't protect against most top-rank rounds. The hull composite is only good against lower penetrating APFSDS rounds such as T-55AM, and can also withstand some chemical munitions, but it is not advised to rely on this armour. The rest of the tank (turret and hull sides, lower front plate) has decent protection against chemical rounds due to the add on armour, ERA, and thick turret sides.

While it is slower than Western MBTs at its BR, it is not a slow platform. It holds a fast top speed for both forward and reverse. Despite being a heavy vehicle, the brake distance is surprisingly low, between 20-30 m at top speed. It has the ability to do neutral steering relatively fast and, since it comes with all upgrades, it immediately gets the tracks modification which significantly improve this ability. It has little to medium impact when crossing muddy terrain, wet and snowy terrain, but nothing that impacts performance significantly. Thanks to not having the additional armour package, the cross-country capabilities of the Challenger DS are significantly increased, being able to easily traverse and cross over long trenches, deep craters and through steep terrains up to a certain level.

The Challenger bears the 120 mm L11A5, an updated but essentially identical version of the gun found on the Chieftains. It keeps the same ammunition as the Challenger Mk.2 and previous Chieftain Mk.10, making the ballistic performance identical. The L23 comes as the stock round with a significant armour penetration at the cost of reduced penetration angle. L23A1 has much better angle penetration at the cost of reduced armour penetration.

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:

• Short reload time
• Can be hard to penetrate hull down
• Has a great reverse gear

Cons:

• Only 4 shells in the ready rack
• Heavy tank
• Driver's optic are huge which makes it a huge weak spot
• Can be easily ammoracked
• Sides are riddled with fuel tanks which makes it prone to catch fire from enemy shells

History

After the introduction of Challenger in 1983 as the new MBT for the British Army in different units, there were debates on its reliability due to its inferior overall performance in the Canadian Army Trophy of 1987. As the Invasion of Kuwait by Iraq in 1990 and the subsequent Operation Desert Storm (Gulf War) began in 1991, the Challengers were given the chance to show their worth.

The British Army deployed the 1st Armoured Division to the Middle East alongside three armoured brigades with Challenger tanks, some even with the latest Mk.3 series with new ERA packages installed in Saudi Arabia by late 1990. After the deadline for complete withdrawal of Iraqi forces passed, the coalition started the assault on 17th January, 1991, after which the Challengers destroyed and captured hundreds of Iraqi tanks (ie. T-55A, Type 69-IIa) while received no loss from enemy fire. Operation Desert Storm was where the Challenger held the world record of the longest tank-to-tank kill, done by the callsign of 11B from the Royal Scots Dragoon Guards, achieving a destruction at around 5.1 km away on 26th February, 1991.

The livery of Challenger DS belongs to a tank with a callsign Zero Charlie (ØC) of A Squadron to an unknown unit in British Army.
