The Deredeo Dreadnought is a walking heavy weapons platform, designed to combine superior firepower with the flexibility and durability of a Dreadnought chassis. Though highly resource-intensive to produce and maintain, its undoubted survivability and killing power ensures the Deredeo is in high demand by Traitor and Loyalist Legions alike from the few Forge Worlds able to fashion them.

Tactical squads are the mainstay of the Space Marine Legions and the force by which the Great Crusade has reconquered much of the galaxy. By the fighting power of thousands of superhuman warriors such as these, armed and armoured for battle in the harshest of environments and the deadliest of war zones, the enemies of Mankind have been crushed repeatedly. The Legion Tactical squad is a highly flexible infantry unit, able to attack or defend at will, assault heavily fortified positions and take and hold strategic objectives, or simply slaughter an enemy comprehensively in almost any situation.

The Horus Heresy is the bloodiest conflict humanity has ever known, a galactic civil war in which Space Marines of the Legiones Astartes turn devastating weapons upon those they once called brothers.

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.

Cerastus Knights are sophisticated and towering war-suits, with speed and agility that far exceeds the lumbering Questoris-class. The Knight Lancer is the most widely-known variant of the Cerastus chassis, held in high esteem by more impetuous House scions. Its protective ion gauntlet and potent shock lance are perfectly suited to duelling titanic foes face-to-face, and such pilots often race ahead to seek glory by vanquishing the enemy's most prized war machines.

The Vindicator is a dedicated siege tank, deployed by the Legiones Astartes to breach enemy fortifications and destroy the heaviest enemy vehicles. Slow, ponderous, but heavily armoured, these tanks rumble into range before unleashing a devastating salvo of demolisher shells or piercing bursts of energy from a magna laser destroyer. Vindicators are especially useful in the confined terrain of cities or other enclosed battlefields, where they can smash buildings to broken ruins and forge a path through otherwise impassable obstacles.

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.
