Overview

The Leman Russ Punisher eschews anti-tank effectiveness for greatly increased anti-infantry firepower. There are few other tanks in the Imperial Guard armoury are capable of pouring as much ammunition out at the enemy as the Punisher. The tank's crews have reputions for being gung-ho and trigger happy.

Weaponry

Based off the Leman Russ chassis, the Leman Russ Punisher still has options for sponson mounted support weapons, a hull mounted weapon, and a pintel weapon attached to the tank's top cupola for the commander or any other crew to use to use.

However, the Leman Russ Punisher's main weapon, the Punisher Gatling Cannon, is it's trademark armament, and is widely known as one of the fastest firing slug throwers in the Imperium's arsenal.

Firing at a rate of fire faster than that of a Vulcan Mega-bolter, the Punisher Gatling Cannon is top of the line in anti-infantry capability.

For a pair of side sponsons, the Punisher has access to all the sponsons available to other Leman Russ variants. It can utilize heavy bolters, heavy flamers, plasma cannons, or multi-meltas.
