The Leman Russ is the main battle tank of the Imperial Guard, and is also the most widely deployed tank in the Imperium. The tank is named after the Space Wolves Primarch, Leman Russ. The Leman Russ was first developed some time during the Great Crusade in the late 30th Millennium, but all information about the vehicle from that ancient time is missing or non-existent. The Leman Russ tank is the mainstay of most Imperial Guard armoured regiments and is produced by the millions in Forge Worlds and Hive World manufactorums across the galaxy. The tank is also used by many other Imperial forces such as Planetary Defence Forces and the Adeptus Arbites. Far from a sophisticated vehicle, the Leman Russ was designed and built with reliability and versatility in mind. It can survive the worst the galaxy can throw at it, and can run on almost any liquid fuel. Though slow, its frontal armour is strong enough to withstand the multitude of weaponry wielded by the enemies of the Emperor of Mankind. Its side and rear armour remain thinner to reduce the strain on the tank's engines. This characteristic does make the Leman Russ vulnerable to assault from these angles, requiring infantry support, other tanks or very careful operation to protect the vehicle. The Leman Russ can perform to its optimum capabilities when all of these elements are combined during an Imperial armoured advance. The Leman Russ is crewed by a minimum of four crewmen, including a commander, gunner, loader and driver. Side sponson weapons may be added, each of which requires an additional crew member to operate. The Leman Russ is simple to operate, but very loud and uncomfortable for its crew. Due to the noise, intravehicle communication is only viable by an enclosed intercom system, with the commander having access to an external Vox-caster.

Capabilities

The Leman Russ seems to be a crude, slow, and poorly designed tank, but it is an excellent benchmark for the abilities and advanced nature of Imperial technology. Despite being famed for its simplicity and reliability, the Leman Russ is an extremely complex and advanced main battle tank. The tank's frontal armour is 150 millimetres thick, meaning it can withstand all but the most dedicated anti-tank weaponry, yet its side armour is much thinner. With a range of 105 miles on just 360 gallons of fuel, a feature the later Land Raider would also possess, the Leman Russ can accept almost any sort of combustible fuel. Though its top speed is a mere 29 kilometres/hour, this is mostly because of extremely heavy governing of the tank's engine, as a properly tuned Leman Russ can reach speeds in excess of 70 kilometres/hour. The Leman Russ is also noted for its ability to turn on a dime, and its ability to reverse direction in only seconds remains a "signature move" for the vehicle. The Russ is equipped with a variety of high-tech scanners and Auspex systems, plus inertial dampening technology designed to provide better stability for the firing of the tank's main weapon.

Armament

The basic and most common armament of the Leman Russ tank is a turret-mounted Battle Cannon and a hull-mounted Heavy Bolter. Alternatively, a Lascannon can be mounted on the tank's hull instead of the Heavy Bolter. The Leman Russ 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 a 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, a searchlight, track guards, rough terrain modifications, a dozer blade, and smoke launchers.

Known Users of the Leman Russ Tank

Imperial Guard - The Leman Russ is the basic and most common battle tank of the Imperial Guard, and is the mainstay of nearly all Imperial armoured regiments and companies.
Planetary Defence Forces - The Leman Russ is used by many Planetary Defence Forces stationed on Imperial worlds.
Adeptus Arbites - The Precincts of the Adeptus Arbites will sometimes have a small number of Leman Russ tanks at their disposal, though these vehicles are usually ancient and rarely, if ever, see any action.
The Lost and the Damned - The Lost and the Damned is the name collectively given to the multitude of beings that have turned to Chaos over the millennia, the vast majority of whom are the ordinary mortals who fight for Chaos. They are not a single coherent force, but rather a diverse and infinite collection of warbands and hosts under the leadership of Chaos Champions. These forces take their weapons and vehicles with them, and as many of them were former members of the Imperial Guard or Planetary Defence Forces, they make use of an uncountable number of Leman Russ tanks.

Derivatives

The Leman Russ chassis is the basis for many other Imperial armoured vehicles, including the:

Destroyer Tank Hunter - Tank Hunter
Thunderer Siege Tank - Short-range Artillery
Atlus - Recovery Tank
Bombard - Heavy Short-range Artillery

Patterns

There are several different Leman Russ patterns used by the Imperium. Many of these differences between them are only cosmetic, but several offer increased interior room, better performance, or increased armour.

Mars-Alpha- The Mars-Alpha Pattern Leman Russ has a slightly larger chassis interior than any other pattern. The Mars-Alpha Pattern is commonly used for Leman Russ tanks that serve as squadron or regimental command vehicles, as the extra space allows for the installation of more powerful communications equipment and provides more room for a command staff.

Ryza
Gryphonne IV
Stygies VII

Variants

The Leman Russ tank can exchange its main weapon for a different weapon which changes the tank's designation and battlefield role. These variants include:

Conqueror

One of the less common Leman Russ variants, the Leman Russ Conqueror is only produced in any significant quantities on the Forge World of Gryphonne IV, where the Standard Template Construct plans for the design were originally rediscovered. Armed with the Conqueror Cannon, as opposed to the standard Battle Cannon, the Conqueror sacrifices outright destructive power in exchange for improved mobility and accuracy whilst firing on the move. The Leman Russ Conqueror comes standard with co-axial mounted Storm Bolters and searchlights, removing the need to expose a crew member to fend off oncoming enemy infantry. The back of the turret houses an armoured ammunition access hatch, making re-arming the tank quick and easy. This hatch is also used to dispose of spent Conqueror Cannon shells.

Demolisher

One of the most common Leman Russ variants, the Leman Russ Demolisher is equipped with the Demolisher Cannon, and is designed as a short-range bombardment and line-breaker tank. The extreme power of this weapon is hampered by its short effective range. Demolishers are valued as close heavy fire support vehicles by the Imperial Guard's infantry units, and it is the most common variant of the Leman Russ that is equipped with Plasma Cannons and Multi-Meltas on its sponson mounts in order to make them more effective against heavily armoured units.

Executioner

A variant now produced only on the Forge World of Ryza, the Leman Russ Executioner is armed with the Plasma Destroyer, a slightly more powerful version of the Plasma Cannon. A poorly understood and temperamental weapon, the Plasma Destroyer is often criticised for its high power requirements, limiting the tank's effectiveness in extended engagements.

The turret features emergency vents, heat shielding and coolant to both protect the crew and the weapon itself from damage should a plasma containment field failure occur. However, due to bad design, the coolant feed lines run outside the turret, and are prone to damage, rendering the emergency systems less than reliable. Crews dislike being made to work in the Executioner, and are prone to bailing out at the first sign of trouble. Crews who willingly command these tanks are often seen as foolhardy, extremely brave, or insane. However, those crews who do stick to their tanks are among the best tank-killers in the Imperium, able to take out even the most heavily armoured tanks and buildings due to their powerful main gun. When the tank takes too much damage, the plasma containment field for the main gun can short out, releasing an expanding shock-wave of energy that can incinerate any infantry close to the vehicle.

Vanquisher

A rarer and more advanced variant of the standard Leman Russ, the long-barrelled Vanquisher Cannon mounted on the Leman Russ Vanquisher is capable of firing powerful anti-tank shells. In addition, a Storm Bolter is mounted co-axially to the main cannon. However, Vanquishers are becoming increasingly rare in Imperial service due to the actions of the Ork Warlord Arrgard the Defiler, who scoured the Forge World Tigrus in the 35th Millennium, destroying the only existing template for constructing the Vanquisher Cannon in the process.

Annihilator

The uncommon Leman Russ Annihilator variant replaces the standard tank's Battle Cannon with a pair of Twin-linked Lascannons. This is similar to the identically-designated Predator Annihilator tank of the Space Marines from which this variant of the Leman Russ takes its name. This change requires the addition of extra power-cells inside the tank, but these use the space saved by the fact that the Battle Cannon's ammunition no longer needs to be stored. The Annihilator's twin Lascannons turn this variant into a true tank-hunter and it is in this role that the tank excels. Of course, such sophisticated tactical planning is not regarded as important by the Death Korps of Krieg Imperial Guard regiments that have been the most common users of this variant of the Leman Russ. As such, where other regiments would regard this tank-hunter as a defensive weapon, the Death Korps uses them as offensive weapons to be thrown into the open assault across no-man's land during a planetary siege.

Exterminator

The infrequently seen Leman Russ Exterminator variant is armed with turret-mounted Twin-linked Autocannons and is generally deployed in an anti-infantry role. Sometimes the Exterminator is also utilised as a stop-gap measure for anti-air defence due to its rapid firing speed. It is especially effective against lightly armoured horde armies such as the Orks or Tyranids, and when the tank is equipped with all anti-infantry weaponry, such as Heavy Bolters, it is capable of laying down a withering hail of ballistic fire. While the Twin-linked Autocannons have recoil dampeners they lack a muzzle brake or flash suppressor. The Exterminator is unique in that it is also used in small numbers by the Space Wolves, making it the only Leman Russ variant fielded by any Space Marine Chapter.

Eradicator

A simple, destructive vehicle, the Leman Russ Eradicator was instrumental in the urban conflict on Khai-Zhan. Its main weapon, the Eradicator Nova Cannon, gained a fearsome reputation as a powerful anti-infantry weapon. The weapon's heavy, high-calibre ballistic shells are capable of destroying both enemy barricades and any infantry sheltering behind them with a highly volatile sub-atomic charge. This makes the Eradicator extremely effective in cities, jungles or other dense terrain. With a blast radius close to that of the Demolisher Cannon, but possessed of a longer range, the Eradicator Nova Cannon can effectively clear buildings of enemy infantry before they can even get a shot off.

Punisher

The Leman Russ Punisher is the most potent anti-infantry vehicle in the Imperial Guard, and amongst the best anti-infantry vehicles in the galaxy. Armed with the Punisher Gatling Cannon, a large, multi-barrelled ballistic weapon, it is known as one of the fastest-firing slug throwers in the Imperium's arsenal. The Punisher can shred even the heaviest of infantry units with punitive ease, however, the Punisher can be outmatched by enemy tanks in a head-to-head fight, and commonly only works with other Leman Russ tank variants to make up for the loss of anti-tank firepower. The crews of Punishers have reputations for being very gung-ho and extremely trigger happy.

Ork Looted Leman Russ

Orks have also seen the usefulness of the Leman Russ and almost always loot one or more from a battlefield where they have faced the Imperial Guard should the chance arise. However the Orks' incompetence with ranged weaponry has drastically decreased the effectiveness of the tank's main weapons. Looted Leman Russ tanks, and just about any other tank or vehicle, are very popular with the Death Skulls tribe of Orks who are very good at "liberating" enemy vehicles. The Death Skulls like to loot a vehicle, repair it, and then use it against the enemy during the same battle. Sometimes the Orks will "enhance" their looted vehicles with more weapons, armour, and garish paint jobs which match their "unique" aesthetic style.
