The Scorpius is a pattern of armoured vehicle created, at the behest of the Space Wolves Legion, to provide indirect fire support for assault actions via its advanced missile launcher systems. Well-suited to such high intensity operations, it was approved for service across the entire Legiones Astartes before the outbreak of the Horus Heresy. Alongside the Scorpius, several other mobile artillery units are commonly seen in the arsenals of the Legiones Astartes, including the Whirlwind. Mounting an indirect-fire multiple missile launcher, the Whirlwind provides saturation fire, bracketing a large area with its explosive payload.
