The Horus Heresy Legion Astartes Scorpius Missile Tank

Rugged and well-suited to high-intensity operations, the Scorpius missile tank is favoured across the Legiones Astartes as a source of manoeuvrable artillery support. Often collectively referred to as 'Whirlwinds', tanks mounted with multi-missile launcher systems are a vital part of any Legion's war machine, providing long-range covering fire and trench-breaking barrages. The Scorpius itself only entered service shortly before the Horus Heresy, created at the behest of the Space Wolves Legion in a campaign against fortified xenos bastion-cities – where its performance quickly saw it approved for widespread use.
