Warhammer: The Horus Heresy – Legions Imperialis: Mechanicum Acastus Knights Asterius

The Deredeo Dreadnought is a walking heavy weapons platform, designed to combine superior firepower with the flexibility and durability of a Dreadnought chassis. Though highly resource-intensive to produce and maintain, its undoubted survivability and killing power ensures the Deredeo is in high demand by Traitor and Loyalist Legions alike from the few Forge Worlds able to fashion them.

The Valdor Tank Destroyer mounts a devastating neutron laser – each a meticulously wrought iteration of a recovered relic of the Dark Age of Technology. Though rare, they're in high demand as the Solar Auxilia are called upon to fight the Legiones Astartes and their fighting vehicles.

The Malcador Infernus is, in effect, a huge flamer on tracks, with a fuel trailer towed behind it. They are generally deployed to lead advances against enemy forces occupying especially dense terrain, such as trench lines, city ruins, or heavily forested areas.

The Arvus Lighter is a utility shuttle used by the Imperialis Armada for transferring supplies or small groups of personnel. It's a workhorse, used to insert infantry sections and command units into a war zone with pinpoint accuracy.
