This Sons of Horus Arquitor Bombard with Spicula Rocket System was in the displays at Warhammer World.
The Legion Arquitor is a heavy artillery platform designed to operate at the forefront of a Legiones Astartes advance. Equipped with a reinforced chassis and brutal short range firepower, it is called upon to break the most stubborn of fortifications or to annihilate massed enemy infantry and armour. The spicula rocket system fires rippling salvos of unguided missiles that crash down on enemy positions, creating massive cumulative blasts that can scatter whole formations.
