The Leman Russ Demolisher is a variant of the Astra Militarum'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 Demolisher variant differs from the standard pattern Leman Russ in that its main weapon is a Demolisher Cannon, as opposed to the standard Battle Cannon. The Demolisher Cannon sacrifices range for additional firepower, and is capable of inflicting unusually heavy damage on a target, or outright destroying enemy fortifications. As a result, the Leman Russ Demolisher is often used as a close-support tank for breaking enemy lines and sieges.

When facing enemy armour, the lack of range of the Demolisher Cannon is a major disadvantage, but if the Leman Russ Demolisher manages to close the gap, its massive shells can knock out super-heavy tanks with ease, and even threaten Titans with their devastating power. Of the many variants of the Leman Russ main battle tank, the Demolisher is the most common, and the most appreciated by the regular Guardsman, who knows he can rely on his "Big Brother." Their use in conjunction with the infantry is so efficient that most Leman Russ Demolishers are assigned directly to a standing Imperial Guard infantry company instead of being formed up into separate armoured regiments, although such regiments, often nicknamed "Siegebreakers," also exist.

The Leman Russ Demolisher was devised for but one task -- line breaking. The Leman Russ Demolisher's main weapon, the Demolisher Cannon, is a small ballistic cannon that fires large shells at short distances, the utter lethality of which makes this pattern of battle tank the undisputed king of the close-range firefight. With additional armour plating fitted on its front, the Demolisher is capable of pushing through devastating fire to close the gap between Imperial and enemy lines.

The Leman Russ Demolisher, 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, a Hunter-Killer Missile Launcher, improved communications equipment, a Searchlight, a mine sweeper, a pintle-mounted Heavy Stubber or Storm Bolter, track guards, rough terrain modifications, a Dozer Blade, and Smoke Launchers. Due to the short range of the Demolisher Cannon, all Leman Russ Demolishers have Extra Armour Plating to increase their chances of getting close enough to heavily defended enemy fortifications to deliver a killing blow.
