The Sicaran Arcus Strike Tank, also known as the Acrus Strike Tank or the Sicaran Arcus 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 Arcus variant of the Sicaran is a fast strike tank, replacing the standard Sicaran's twin-linked set of the highly sophisticated Herakles Pattern Accelerator Autocannons with a set of twin-linked Arcus Launchers or a set of twin-linked Rotary Missile Launchers.
