REPULSOR - GRAV RAIDER!
"This new tank is one of the new armoured vehicles that accompanies the Primaris Space Marines to war. Like their arms and armour, it was forged on Mars, and is recognisably of the same STC origins as its predecessors. Could this be ancient technology long lost and uncovered once more, or has Cawl been “tinkering” with Omnissiah-blessed technologies? This new war machine stands ready to crush its way to war alongside the tried and tested Predator and Land Raider tanks of the Space Marine Chapters.
The Repulsor is on its way soon. Stay posted for more details."
