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 bolters are the largest bolt weapons available to infantry, unleashing a storm of shells that tear apart enemy formations, while missile launchers are prized for their versatility, offering a variety of explosive munitions suited to eliminating infantry, tanks, or aircraft.

The Sicaran is one of the most advanced armoured units in the arsenal of the Legiones Astartes, a fast-moving destroyer tank designed to outflank enemy formations before unleashing an overwhelming onslaught of mid-range firepower. Though its chassis supports a number of variants fielded throughout the Legions, the core Sicaran battle tank remains a versatile favourite. Armed with Herakles-pattern accelerator autocannons, it provides high-volume, high-velocity fire support that can rip through infantry and vehicles alike – its sophisticated sensors tracking swift-moving targets and pinpointing vulnerabilities in enemy armour.

Praetors are the mightiest warriors and battle-leaders of the Space Marine Legions, second only to the god-like Primarchs in martial skill and generalship. Those that choose to march to war clad in Cataphractii Terminator armour place great value in its enhanced resilience, which can stoically weather even the heaviest of incoming fire. These hulking warlords stride into the thickest fighting, leading their warriors to victory across hundreds of battlefields.

Terminator suits are the ultimate in personal armour technology, gifted to the finest veteran forces of the Legiones Astartes. Squads clad in Terminator armour become devastating frontline assault units, able to withstand the heaviest enemy fire and deliver a ruthless hammer blow to crush their foes. Cataphractii suits are among the earliest designs of Terminator armour, and still the most heavily-protected of their kind, with slab-like ceramite pauldrons that house additional shield generators at the cost of mobility.

Ahzek Ahriman has the unique distinction of being both the first and last Chief Librarian of the Thousand Sons, and is the most gifted mystic among their already-formidable psyker corps. A respected commander even before his Legion's reunion with its missing Primarch, Ahriman's keen intelligence and talent in warpcraft soon made him Magnus' foremost apprentice, but his greatest strength is his indefatigable will. Ultimately, this determination would see him play a pivotal role in the Burning of Prospero – and walk strange and terrible paths long after the close of the Horus Heresy.

The battles of Warhammer: The Horus Heresy are rife with swift Reactions, mighty Warlords, and forbidden Psychic Powers. This handy deck of reference cards makes it easy to keep track of new rules and mechanics, so you can focus on your strategy. These cards will ensure you can take full advantage of the new Reaction system – they work as both a reminder to use them, and a rules reference for you and your opponent.

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 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.

Perhaps the most advanced Dreadnought engine in the arsenal of the Great Crusade, the Contemptor Dreadnought fuses traditional technologies with arcane cybernetic lore. A powerful atomantic reactor fuels the Dreadnought's impressive speed and strength, while also supplying the defensive energy fields that further increase its battlefield durability. Equipped with a versatile armoury of weapons that allow it to serve as a mobile heavy weapons platform, assault powerhouse, or versatile linebreaker, the Contemptor has found a place within every Legion, no matter their preferred tactics.

The Warmaster’s own Legion are unleashed on the field as dark exemplars of the Astartes, cursing the Emperor’s name. Show your loyalty to Lupercal with this set of Sons of Horus-themed dice.

The Space Marine Legions of the 31st Millenium field a diverse and formidable range of genetically-enhanced warriors and advanced war machines, superior to any other military force in the galaxy. As an Age of Darkness falls across the stars and the fires of rebellion rage out of control, the armies that were used to forge the Imperium turn upon each other in an apocalyptic civil war – the Horus Heresy.

The Spartan Assault Tank is a huge armoured conveyer, designed to bear a great contingent of troops into the heart of enemy lines, weathering weapons fire that would be the death of any lesser vehicle. Protected by a sealed shell of legendarily durable plating, the Spartan's carrying capacity exceeds anything but a true super-heavy transporter, while retaining an impressive speed across the battlefield. Its quad lascannons make the Spartan a fearsome tank destroyer, while its secondary armaments allow it to sweep infantry from its path. The Spartan takes pride of place in the armouries of many Legions, its presence limited only by its sheer scale.

The Imperium stretches across countless worlds, a newborn empire on the brink of ultimate victory. Yet at the peak of this golden age of conquest, the galaxy has been plunged into an Age of Darkness. Horus Lupercal, Warmaster of the Emperor's armies, has turned against his gene-father – and the eighteen Space Marine Legions, once united in a Great Crusade to consolidate all humanity beneath the Emperor’s banner, are riven by betrayal. This is the Horus Heresy – the bloodiest conflict humanity has ever known, civil war on a galactic scale, in which superhuman soldiers clad in advanced armour turn devastating weapons upon those they called brothers. Where do your loyalties lie?

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.

Tactical Squads are the mainstay of the Space Marine Legions, highly versatile infantry units that can attack or defend at will, assault heavily fortified positions, and take and hold strategic objectives – or simply slaughter the enemy – in almost any terrain or situation. All 18 Legions make heavy use of Tactical Squads in different ways – it is by the fighting power of thousands of superhuman warriors such as these, armed with deadly bolters and armoured for battle in the harshest of war zones, that the Imperium has beat a bloody path across the galaxy at the head of the Great Crusade.

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.
