The Astra Militarum is a monolithic military force, soldiers and vehicles beyond number spread across war zones throughout the galaxy. Its inexhaustible armies are the Emperor's hammer and the Imperium’s shield. They defend countless worlds from invasion and rebellion, and wrest back lost territory in grand crusades. Faced with ancient monsters and extragalactic horrors, the troops and tanks of the Astra Militarum stand together, acting as one to crush any opposition with brutal and undaunted resolve.

The Adeptus Custodes rarely deploy in large numbers, but they are a hurricane force of destruction when they do. Trained in the arts of the Martial Ka'tah, their armoured infantry steadily advance – an army of gene-forged golden warriors who wield ornate powered blades with integrated firearms, every strike and shot a graceful killing blow. These are the chosen guardians of the Golden Throne, the Emperor's emissaries and executioners, and they meet any foe with the conviction and confidence of demigods.

Dominus-class Knights are among the largest available to any Knight house. These walking fortresses march relentlessly into the fight, armed with weapons capable of levelling entire armies, gunfire scattering uselessly off their ion shields. The Knight Valiant defeats its enemies through overwhelming firepower at close range. Its conflagration cannon unleashes a searing, inescapable firestorm, easily annihilating incoming hordes and smashing through opposing battle lines, while its thundercoil harpoon can destroy tanks and monsters with impunity.

More rolling fortress than vehicle, the Baneblade super heavy tank is possessed of overwhelming firepower. Wherever a Baneblade sees battle, it becomes the centre of the battle line, Imperial Guardsmen and even smaller tanks sheltering in its lee as its enormous primary cannon and numerous other guns hammer the foe into submission.

The Adeptus Custodes are an army unlike any other. Each member would be considered a mighty hero by lesser warriors, capable of besting entire units or even armies of weaker foes. When they assemble in larger groups, they are a gleaming golden host, their speed and agility combining with frightening strength, skill at arms, and tactical brilliance.

The Adeptus Mechanicus march to war as a disturbing fusion of flesh and machine, ruling Tech-Priests and fanatical cyborg followers raising modified voices in binharic praise of the Machine God. Purge Corps Deltic-9 are equipped to scour the contamination of enemy presence from locations of strategic or exploratory importance, employing cybernetic speed and terrifying weapons. Cavalry and winged Pteraxii unleash gouts of purging flame, before radioactive Skitarii bring up the rear to reclaim whatever remains.

The Astra Militarum are the backbone of the Imperium's largest armies. They are the men and women who hold the line, a bulwark standing between Humanity and a nightmarish galaxy of horrors. Amongst the Astra Militarum's massed regiments, the born soldiers of Cadia are some of the most disciplined warriors to be found – tough marksmen trained for a lifetime of grim duty.

The Knight Preceptor is a Questoris-class close-ranged powerhouse. Its design is intended to exemplify the core tenets of the Code Chivalric in battle

Where the Triumph of Saint Katherine marches, there shines the Emperor’s radiance.

The Rogal Dorn Battle Tank is a lumbering behemoth, equally suited to anchoring a battle line, or grinding forward in support of an assault. Bristling with thunderous guns, these hulking armoured fighting vehicles pound breaches in enemy’s defences with enormous shells, and tear apart infantry with raucous storms of fire.

Small and agile compared to their lumbering kin, Armiger-class Knights are still war machines of incredible power. Piloted by young squires or lowborn pilots, Armigers act as mobile support and outriders to keep larger Knights from being surrounded, receiving commands from their Noble lords through the Helm Mechanicum. Among these nimble engines, Armiger Warglaives are fearsome hunters of enemy armour, armed with a deadly close combat weapon and a thermal spear that can melt through the toughest bunkers.
