The Sicaran Punisher Assault Tank, or simply Sicaran Punisher, is a variant of the standard Sicaran Battle Tank. The Sicaran Battle Tank was an Imperial main battle tank and one of the most advanced armoured vehicles used by the Space Marine Legions during the Great Crusade and the Horus Heresy in the late 30th and early 31st Millennia. The Sicaran Punisher variant came to be used by the Space Marine Legions during the final days of the Great Crusade, along with several other Sicaran variants. The Punisher is an anti-infantry-focused assault tank, replacing the standard Sicaran's twin-linked set of the highly sophisticated Herakles Pattern Accelerator Autocannons with a massive Punisher Rotary Cannon.
