The Leman Russ Vanquisher is a more sophisticated version of the basic battle tank. The Vanquisher is becomingly increasingly rare as the skills and technology required for the construction of the long Vanquisher battle cannon were lost when the Forge World of Tigrus was overrun and scoured by Ork Warlord Arrgard the Defiler in M35. Those Vanquishers that remain in service are carefully maintained and only granted to tank crews who have proven themselves in the heat of battle.
