The Caladius Annihilator Grav-tank is a multipart plastic miniature kit for the Legio Custodes faction in Warhammer: The Horus Heresy. It builds a single, swift and heavily armoured grav-tank intended to anchor the heavy-weapons element of any Custodian battle line.

Mounted on an advanced antigrav chassis, the Caladius Annihilator forgoes the tracks of Legiones Astartes and Solar Auxilia vehicles in favour of sleek, fast manoeuvring across the battlefield. Its turret houses a devastating twin Arachnus blaze carronade, capable of shredding even power-armoured infantry in an instant, while the hull offers a choice between a twin lastrum bolt cannon for cutting down infantry or a twin neutronium cascade projector for clearing hordes. Combining raw firepower with protection and mobility, the Caladius Annihilator stands among the most formidable armoured units of its size in the Imperium's arsenal.

The kit comprises 116 plastic components and is supplied with a 150mm by 95mm oval base, a Custodes vehicle flight stem, and a Legio Custodes vehicle transfer sheet featuring 210 high-quality waterslide transfers, including Custodian iconography and battle honours to personalise the finished model. A construction guide is included to aid assembly.

This miniature requires assembly and is supplied unpainted; plastic glue and hobby tools/paints are recommended but sold separately.
