Leman Russ Conqueror-0

A Leman Russ Conqueror makes its way across the battlefield.

The Leman Russ Conqueror is a variant of the Imperial Guard's primary main battle tank, the Leman Russ. The Leman Russ is named after the Primarch of the Space Wolves Space Marines Chapter, Leman Russ, and is one of the most common armoured vehicles used by the Imperium of Man.

The Leman Russ Conqueror variant differs from the standard pattern Leman Russ in that its main weapon is a Conqueror Cannon, as opposed to the Battle Cannon. The Leman Russ tank has many variants, and the Conqueror is one of the most uncommon, as the Standard Template Construct (STC) designs used in its construction were only recently rediscovered by the Adeptus Mechanicus.

Although the Leman Russ Conqueror is relatively new to the Imperium's arsenal, it has already proven itself as a capable line-breaker tank, used to penetrate and surround the formations of enemy armour.

The Standard Template Construct designs for the Leman Russ Conqueror were rediscovered on the Forge World of Gryphonne IV sometime during the 38th Millennium. When the designs were originally found many within the ranks of the Adeptus Mechanicus feared that the Conqueror Cannon's smaller size would result in a loss of firepower and poor battlefield performance when compared to the standard Leman Russ' Battle Cannon, but these fears were laid to rest during the weapon's field testing.

The weapon was shown to have greatly reduced recoil due to the gun's torsion bar counter-balance mechanisms, and this provided the new tank design greater accuracy when firing on the move. The weapon's smaller size also gave the vehicle greater mobility, and allowed its loaders to keep up a high rate of fire. The weapon's use of smaller shells allowed the Conqueror to carry more ammunition and thus made it less reliant on re-supply during operations. The space saved in the turret also allowed for the use of a co-axial Storm Bolter.

The Conqueror is one of only two Leman Russ variants that make use of a co-axial weapon, the other being the Leman Russ Vanquisher. The turret also has additional armour plating on the forward side, improved air-intake valves and vents, and a rear hatch that can be used to quickly re-arm the tank and also to dispose of spent shell casings without a crew member having to leave its armoured interior.

Proving Grounds

The entire first production run of Leman Russ Conqueror tanks was issued to the Skitarii legions of Gryphonne IV, and their first action was to partake in the Castra Campaign. During the campaign the Adeptus Mechanicus Skitarii and the Legio Gryphonicus Titan Legion were tasked with the destruction of enemy forces that were held up inside of Hive Castra Septus. The Conqueror-equipped Skitarii legions were able to keep up with the advance of the Titans as they attempted to encircle the hive city and trap the enemy combatants within.

Enemy forces were unable to make it past the combined force of the Titans and the Conqueror tanks and after the Titans created breaks in the defender's defensive line the Conquerors rushed into their midst, completely annihilating the Traitors. After this success, the Leman Russ Conqueror was put into full production and was slowly but steadily exported to Imperial Guard armoured regiments around the galaxy.

Sometime during the 39th Millennium the Adeptus Mechanicus Munition-Adepts of Gryphonne IV tried to create a new type of shell for the Conqueror Cannon. This shell, known as the Auger Shell, was supposed to increase the tank's firepower, but was considered a complete failure during testing, and the production of the Auger Shell is no longer permitted for the design.

At Present

In the 41st Millennium the Leman Russ Conqueror is an uncommon sight in most Imperial Guard regiments as the STC designs used in its construction are found only on the Forge World of Gryphonne IV.

The original designs that were recovered on Gryphonne IV now reside on Mars waiting to be processed for distribution across the Mechanicus' manufactorum network and at present there are several other Forge Worlds lobbying to gain access to them.

The Leman Russ Conqueror is well-liked by its crews due to its speed, mobility, and high rate of fire, and it has unofficially became known as a "breakthrough" tank because of its common tactical deployment by Guard commanders to exploit gaps in the lines of enemy armour.

The Leman Russ Conqueror's main weapon, the Conqueror Cannon, is a smaller and less powerful version of the Battle Cannon used on the baseline Leman Russ, but the reduced size and firepower allow the tank to move while firing and maintain a higher rate of fire. The Conqueror is also one of only two Leman Russ tank variants that have a co-axial weapon mounted on the tank's turret, the other being the Leman Russ Vanquisher.

The Conqueror, like all Leman Russ variants, can be equipped with two sponson mounts, one on each side. The most common configuration for the sponson-mount is 2 Heavy Bolters or 2 Heavy Flamers. Leman Russ tanks that are a part of an unusually well-equipped armoured regiment sometimes have 2 Multi-Meltas or 2 Plasma Cannons as their sponson weapons.

The tank can also be equipped with camouflage netting, extra armour plating, a Hunter-Killer Missile Launcher, improved communications equipment, a mine sweeper, a pintle-mounted Heavy Stubber or Storm Bolter, track guards, rough terrain modifications, a dozer blade, and smoke launchers. All Leman Russ Conqueror tanks are equipped with searchlights mounted on top of the turret which are used to illuminate enemies and are also used for nighttime communications in case of a Vox failure.
