Each company in a Chapter of the Adeptus Astartes falls under the command of a Captain.

Primaris Techmarines stride selflessly through oncoming fire to soothe the machine spirits of wounded war engines, deftly peeling back damaged armour plates to repair burnt-out cabling and bending warped panels back into shape with their servo-arms and mechadendrites.

Intercessors equipped with powerful jump packs soar over the battlefield, slamming into the foe like a hammer from the skies. They swiftly cut down all opposition with point-blank pistol fire and furious slashes from their chainswords, before launching off to engage the next target.

The Space Marines of the Adeptus Astartes are Humanity's greatest defenders – genetically enhanced post-human warriors raised to know no fear, armed and armoured with the best wargear the Imperium can provide.

Before the molten ire of an Eradicator Squad, heavy armour and defended positions stand little chance. Eradicators wear the heavier Gravis pattern of Mk X power armour, allowing them to stride unharmed through waves of incoming fire before bringing their own destructive weaponry to bear at close range.

The Space Marines are known as the Angels of Death, and the title is never more appropriate than when they attack using Drop Pods. Drop Pod assaults are the ultimate weapon of terror and surprise, aimed right at the heart of the foe

With pinpoint accuracy, the Gladiator Lancer picks off the heaviest enemy armour, the laser destroyer punching smouldering holes in their hulls. Such is the range of its heavy cannon that it can eliminate threats to the Space Marines before they encounter them, storming past burning wrecks to claim their objectives.

Eyes blazing and fists crackling with roiling energies, Space Marine Librarians stride into battle to destroy their foes. Some hurl blasts of warp-force that crush their victims to paste, while others twist the flow of time itself or revitalise their brothers with incredible dynamism.

Lieutenants act as the right hands of their Captains by providing tactical flexibility and helping to direct their battle-brothers in war.

Predator Destructors have served the Emperor for more than ten thousand years with resolute steadfastness, proving themselves by slaughtering hordes of enemy infantry, shattering assaults, and laying waste to light vehicles.

The most heroic battle-brothers in a Space Marine company often form an elite retinue, sworn to fight alongside their Captain. These specialists provide vital support as honour guards and aides – Company Champions defend their Chapter's honour with martial excellence, Ancients guard its inspirational banners, and Company Veterans lay down hails of fire from relic bolt weapons.

Captains are fearless leaders among the Space Marines, each one a masterful tactician and skilled warrior armed with a variety of weapons and equipment.

The swiftest of the Primaris battle-brothers, Inceptors fill the role of spearhead troops. They hit the enemy in one sudden and overwhelming blow, leaving them reeling as follow-up waves of Space Marines drive home the attack.

Redemptor Dreadnoughts are giant war machines that crush bone and splinter skulls as they bludgeon through enemy ranks.

A strong core of reliable and adaptable warriors that can lay down fire while advancing or holding down terrain is an invaluable aid to any tactician. In the case of strike forces bolstered by Primaris battle-brothers, this role is fulfilled by the Intercessor Squads.

Space Marine Captains equipped with jump packs can lead their warriors as the speartip of an airborne assault. Superlative warriors and inspiring leaders, they thrive at the very forefront of battle, executing ingenious strategies that employ fury and mobility to devastating effect.
