The Vindicator is a Rhino-based siege tank that boasts the most devastating weapon in the Space Marines' armoury - the demolisher cannon. The demolisher cannon is the weapon of choice amongst the Imperium's armies when faced with dug-in enemy infantry in a dense environment such as a cityfight or siege. The terrific blast unleashed by the detonation of the huge demolisher shells can bring down buildings in which the enemy take cover.
