Horus Heresy - Caladius Grav-tank

As powerful as they are, Custodians can’t be expected to tackle every Traitor and monstrous daemon themselves – which is why they maintain a sizable motor pool of advanced and powerful tanks. The Caladius is one such armoured vehicle, skimming over the ground on high-tech hover plates while leaving enemy transports as smoking hulls and infantry little more than red smears thanks to its turret-mounted twin Iliastus accelerator cannon. It can augment this firepower with either a twin lastrum bolt cannon or a twin neutronium cascade projector.
