Cerastus Knights are sophisticated and towering war-suits, far more agile than the smaller Questoris class. The Knight Castigator scythes down hordes of lesser foes that might otherwise overwhelm even a Knight through sheer numbers. Capable of obliterating infantry formations in a thunderous rain of mass-reactive explosions or carving apart light vehicles with ease, the Castigator is renowned for the stoic nature of its machine spirit, and often relied on to hold the line.

Cerastus Knights are sophisticated and towering war-suits, faster and more agile than the smaller Questoris class. The Knight Acheron is a fearsome sight on the battlefield, a reaper of lives designed not only to destroy, but also to inspire terror. The presence of a Knight Acheron warns the foe to expect no mercy, for such grim weapons are only deployed for missions of extermination, to topple the works of the enemy and scour clean their lands with flame.

The Cerberus is a rare variant of the Spartan chassis that uses its massive hull to mount a prototype neutron laser projector, as well as the sizable arc-reactors and radiation shielding needed to operate the weapon. The neutron laser is poorly understood by the adepts of the Mechanicum, but stands among the most effective anti-tank weapons available to the Space Marine Legions, capable of punching through the strongest plating and shorting out its target’s systems with bursts of radiation. The terrible toll the Cerberus takes on its crew is regarded by many commanders as a necessary cost, for this impressive tank can threaten even Titan-class opponents.

The Sicaran is among the most advanced of the armoured vehicles fielded by the Legiones Astartes, a fast-moving destroyer tank with a number of variants favoured throughout the Legions. The Sicaran Venator replaces the standard turret-mounted cannon with a powerful neutron laser that can slice through armoured hulls and blast internal compartments with atomic fire. Coupled with the Sicaran's ferocious speed, this volatile weapon makes the Sicaran Venator an ideal tank hunter, capable of delivering devastating firepower to anywhere on the battlefield.

The Knight Questoris is the most prominent variety of Knight Armour on the battlefields of the Horus Heresy, striding forth alongside the Legiones Astartes, Taghmata Omnissiah, and in the great armies of Knight Households. Such was its popularity amongst the noble scions of the Questoris Households that it was reconfigured in myriad ways with weapon options and hull augments, and given names such as Paladin, Errant, Warden, Gallant, and Crusader to reflect their traditions, lineage, and fighting styles.

Sky-hunters are feared strike units, mounted atop sophisticated and powerful jetbikes. These high-speed craft are more akin to compact aircraft than ground bikes – propelled across the battlefield by jet engines with grav-impellor assistance, they can maintain great speeds for extended periods of low-altitude flight. The jetbike's lift-strength is enough to carry an armoured Space Marine and his wargear along with a variety of heavy weapons mounts and stocks of ammunition, giving the Sky-hunters access to extremely potent, highly mobile firepower.

This multipart plastic kit builds one Legion Scorpius, a mobile artillery piece built on the Deimos-pattern chassis. This tank's turret-mounted missile system is loaded with rotary racks of explosive rockets, ready to saturate whole battlefield zones with a whirlwind of shrapnel and flames. Its launchers can be assembled at a variety of angles, to suggest a devastating volley of direct fire or an arcing salvo of munitions that will wipe out all but the heaviest infantry.

Outside the loyalist Space Marine Legions and the Cult Mechanicum, the Emperor wields forces which are loyal only to him. The Legio Custodes guard the Emperor's person, while the Sisters of Silence stand watch over the Black Ships. The Solar Auxilia are the elite spearhead of the Imperial Army, exemplars of mortal soldiery, while the Divisio Assassinorum is the Emperor's culling blade, aimed at the neck of any foolish enough to imperil his grand dream of Unity.

The Predator is perhaps the best known and most widespread variant of the basic Rhino chassis, equipped with superior armour protection and firepower, but sacrificing the Rhino’s troop transport capacity entirely. The Predator Support Tank is designed to field a wide variety of armament configurations, allowing it to excel in specific battlefield roles.

The Land Raider is regarded by many as the finest armoured fighting vehicle of its class in the Imperium’s arsenal, and is the mainstay battle tank of the Space Marine Legions. It is a phenomenally powerful war machine, its multi-layered composite armour and reinforced hull all but impervious to even heavy weapons, being a sealed unit designed to resist enemy attack from any approach. Intended to serve in almost any environment as both war machine and exploration vehicle, it can operate freely in war zones ranging from acid swamps to rad-deserts without any noticeable impediment to its performance, and can even operate in hard vacuum, ensuring there is no open battlefield on which its armoured wrath cannot be unleashed.

Heavy Support Squads provide the Legiones Astartes with mobile, infantry-portable firepower sufficient to bring down hordes of enemy troops or smash armoured vehicles apart with withering hails of fire, combining devastating armaments with all the flexibility of a footsoldier. Heavy flamers project a roaring torrent of burning promethium capable of incinerating infantry and flushing foes from cover, while multi-meltas reduce enemy tanks to molten slag with a flash of energy, and plasma cannons unleash volatile blasts of superheated matter.

Heavy Support Squads provide the Legiones Astartes with mobile, infantry-portable firepower sufficient to bring down hordes of enemy troops or smash armoured vehicles apart with withering hails of fire, combining devastating armaments with all the flexibility of a footsoldier. Volkite culverins emit scorching heat rays that burn through swathes of infantry, while versatile autocannons spit shells that shred troops and light vehicles alike. Lascannons are the most powerful laser weapons available to Legionaries, firing devastating beams to punch clean through tank armour.
