The Leman Russ Executioner 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 Executioner variant differs from the standard pattern Leman Russ in that its main weapon is the powerful Plasma Destroyer, as opposed to the Battle Cannon. The Executioner is a powerful anti-armour tank, but its temperamental main weapon makes it unsuited for engagements of long duration.
The Executioner is one of the oldest variants of the Leman Russ, and during the Great Crusade entire regiments of this tank were fielded. Gradually, over the millennia, knowledge of plasma technology has been lost, and the Executioner is now a rare relic. When deployed in battle, the Executioner’s Plasma Cannon fires with the fury of a miniature sun, incinerating tightly packed infantry and burning through vehicle armour with ease.
