The Thunderhawk Gunship fulfils a number of roles within the Legiones Astartes, but primarily acts as a drop ship, soaring through both atmosphere and void space to deliver its deadly cargo of Space Marines. It is also a formidable weapons platform in its own right, however, equipped to scour landing zones and engage enemy aircraft

The Knight Questoris is the most common suit of Knight Armour extant in the Imperium during the Age of Darkness, serving as the mainstay of Household forces and configured with a myriad of different armaments. Questoris Knights are frequently fielded in Lances, consisting of multiple noble Scions operating in concert.

The Warbringer Nemesis Titan serves the Collegia Titanica in the role of heavy fire support. It mounts a single Warlord-scale weapon on its upper carapace and Reaver-scale weapons on its arms – sacrificing the speed, armour and manoeuvrability of a conventional Battle Titan in favour of firepower far in excess of its size. With a Mori quake cannon launching world-shaking shells of arcane power, the Warbringer Nemesis is a sight to inspire dread in all but the most battle-hardened enemy Princeps.

The Rhino is the most widely used armoured personnel carrier in the Imperium. Based upon ancient STC technology, the fundamental design is robust, reliable, and easy to maintain, with an adaptive power plant that can run off a wide variety of fuels. Within the Space Marine Legions, the Deimos pattern was the most widespread, serving as the basic armoured transport available to the Legiones Astartes and the foundation on which a number of other war machines were based.

The Solar Auxilia are well equipped to engage in every theatre of battle, against every type of foe. Their adaptability is due in part to their training, but also the advanced wargear they bring to the front. When in need of heavy support from weapons too large for infantry to carry, their Tarantula and Rapier weapons platforms add additional firepower, while remote-controlled Cyclops tanks can be sent in to clear bunkers or even destroy heavy tanks.

The Legiones Astartes employ their superhuman infantry to deadly effect. Clad in durable power-armour, armed with explosive boltguns and an array of heavier weapons, these Legionaries flow through debris-choked cities like water, bringing firepower to bear from unexpected quarters and charging in to strike where the enemy is most vulnerable. With the Legions split between the Loyalist Primarchs and the Warmaster's Traitors, the galaxy's most potent fighting forces now display their might against their own brothers for the first time.

Spartan Assault Tanks carry large numbers of Space Marines into the very heart of the battle. Mounting armaments comparable to the Legion’s super-heavy armoured vehicles and protected by heavy layers of armour plating, these tanks are considered by many to be akin to a mobile fortress.

The Malcador Infernus and Valdor Tank Hunter are both variants of the ubiquitous Malcador tank, using its resilient and mobile chassis to carry specialised heavy weaponry. The raw power of the Malcador Infernus is almost inescapable for its foes, as it shoots terrifying jets of all-consuming flame for extended periods. Conversely, the Valdor Tank Hunter focuses on hardened targets, living up to its name by unleashing its neutron beam laser on armoured vehicles to devastating effect.

Warhounds are the smallest class of ‘true’ Titan, classed as Scout Titans in reference to their common operational role as vanguards to larger Titan battle groups, or support elements to lesser ground forces. When confronting enemy god-engines, Warhounds must rely on their speed, manoeuvrability, and pack tactics to bring down their larger counterparts.

Horus Lupercal, Warmaster of the Emperor's armies, has turned upon his gene-father and sent the Imperium spiralling into bloody civil war. Half of the great Space Marine Legions have sided with the traitorous Warmaster, and countless cohorts of the Solar Auxilia, Knight Households, and Titan Legions march at his side. Now brother fights brother as the Imperium's vast armies tear one another apart in a cataclysm of fire and blood. An age of darkness descends, the likes of which have never been witnessed before.

Warhounds are the smallest class of ‘true’ Titan, classified within the De Bellis Titanicus as ‘Scout Titans’ in reference to their common operational role as vanguards to larger Titan battle groups, or support elements for lesser ground forces. A Warhound's sheer scale and power is enough to turn the tide of most battles – but when facing enemy Titans, they must rely on manoeuvrability and pack tactics to bring down their larger counterparts.

Drop pods are self-contained, recoverable orbital descent capsules, each designed to carry a squad of Space Marines or deliver lethal fire support. They are showered down from orbit like ordnance, allowing surprise attacks and precision combat drops to punch down right into the midst of active war zones.

The Solar Auxilia are the elite corps of the Imperial Army, recruited from all across the galaxy. The soldiers of the Solar Auxilia are equipped with the weapons and gear to persecute war in some of the harshest environments imaginable. Though outmatched individually by the mighty Space Marines, these troops are far greater in number and prepared to throw down their lives for the cause – whether sworn to the Golden Throne of Terra, or the ambition of the Imperium's rebellious Warmaster.

Dire Wolf Heavy Scout Titans are sturdier and more heavily armoured than their Warhound cousins, and function as ambushers in Legio Titanicus battlegroups. Dire Wolves hunker down in forward positions to ambush and obliterate key targets with precise shots from their primary dorsal weapon, while their pintle-mounted arm weapons offer some defence against lesser targets, allowing the Heavy Scout Titans to focus on lining up a firing solution.

The Legiones Astartes wield a staggering array of specialised war machines and weapon platforms, including heavy Dreadnoughts designed to add long ranged firepower, as well as line-breaking heavy assault variants. These assets are typically arranged as support detachments, deployed to enhance and complement the fearsome infantry and tanks of their Legion.

Warlord Battle Titans bestride the battlefields of the Horus Heresy, their thunderous tread heralding destruction. A mainstay of the Collegia Titanica, these Titans are among the largest war machines ever devised by the Mechanicum, and mount a vast arsenal of weapons – Arioch-pattern power claws shred enemy Titans in melee, while plasma annihilators offer intense mid-range firepower.
