Characters / Warhammer 40000 Astartes
"While the enemies of the Emperor still draw breath, there can be no peace."

They shall be my finest warriors, these men who give themselves to me. Like clay I shall mould them and in the furnace of war I shall forge them. They will be of iron will and steely muscle. In great armour shall I clad them and with the mightiest guns shall they be armed. They will be untouched by plague or disease, no sickness will blight them. They will have tactics, strategies and machines such that no foe will best them in battle. They are my bulwark against the terror. They are the defenders of Humanity. They are my Space Marines... and they shall know no fear.
The Emperor of Mankind

The Adeptus Astartes, or Space Marines, are the iconic faction of Warhammer 40,000, power-armored, genetically-engineered super soldiers created to be humanity's ultimate warriors.

Recruited from the Imperium's most warlike cultures, Space Marines are subjected to a brutal crucible of physical training, biological enhancement, and psychological indoctrination. Those who survive the process know no fear or doubt, will never surrender, and will never tire in their endless battle against the Imperium's numerous foes. Their armament is the finest mankind can provide, and their tactics can defeat any foe. They are the Adeptus Astartes, the vanguard of the Imperium's invasion forces and its most resolute defenders. They are the Angels of Death, figures of religious awe to the rest of mankind, and objects of terror for its foes. Though there are fewer Space Marines than there are worlds in the Imperium, they number enough for the task at hand.

The Space Marines were created by the Emperor ten thousand years ago as he led his Great Crusade to reunite the galaxy. Each of these original twenty legions was led by a Primarch, one of the Emperor's clone-sons, and every legionnaire shared his Primarch's genetic template; thus, each Legion inherited their commander's strengths, tactics, culture, and in some cases flaws. Following the disaster of the Horus Heresy, the loyalist Astartes legions were broken down into chapters of roughly a thousand warriors, so that no single man could ever command such an awesome force. Most Space Marine chapters claim a single world as their fief, ruling and recruiting from it, while others are fleet-bound forces that replenish their numbers when and where they can. Recognizing no authority other than the Emperor himself, Space Marines either lead their own crusades to fight the enemies of mankind, or answer petitions for assistance. They stand apart from the Imperium despite serving it, just as they protect humanity despite transcending it.

On the tabletop, standard Space Marines are a well-rounded and forgiving force, and a very popular starting army. The average Space Marine is about as effective as other factions' elite soldiers in both ranged and close combat, while elite Space Marines are some of the most dangerous units on the tabletop. This makes Space Marines expensive in terms of point cost, and therefore (relatively) inexpensive when it comes to collecting an army. As a consequence, Space Marines are almost always outnumbered by their opponents, not that this should worry them - as Rogal Dorn said, "Give me a hundred Space Marines, or failing that, a thousand other troops."

The standard Space Marines 8th edition codex was released in July 2017.

    open/close all folders 

General tropes:

    A - H 
  • Abnormal Ammo: Bolt weapons, the standard Astartes firearms. Instead of bullets, they fire small missiles called bolts with sharpened tips to punch into flesh and armor and mass-reactive detonators that explode them like a grenade. Most bolt weapons use a .75 caliber bolt, while heavy bolters do the same but with a larger caliber round. Some chapters use specialized bolt rounds, such as the psychically-charged Psycannon bolts of the Grey Knights, the razor wire-filled Bloodshard bolts of the Blood Angels, and the silenced Stalker bolts preferred by the Deathwatch.
  • Anachronism Stew: The Land Raider is a World War I tank in space.
  • Angst? What Angst?: invoked All Astartes have this trait to some extent, as part of their enhancement includes making their brains more resistant to post-traumatic stress.
  • Art Major Biology: The only possible way (besides the ever-present Rule of Cool) that the physiological changes and organ implants that go into creating a Space Marine could ever be made to work.
  • Asexuality: By the time a Space Marine is done with training, they have few impulses beyond fighting and killing in the name of the Emperor, and thus have no interest in sex.
  • Awesome Personnel Carrier: The Land Raider, overlapping with Tank Goodness. The highest vehicle armor in the game, weapon options that can obliterate tanks or reduce infantry to ashes or chunky salsa, a "machine spirit" that can assist with shooting or take over for the driver, and it can still carry a squad of Terminators into the thick of combat.
    • The Rhino Transport: Giving your 10-man squads of superhuman armoured badasses a taxi ride to their next ass-whooping session since 1987.
  • Badass Army: One of the best examples in the series.
  • Badass Baritone: Space Marines are frequently described as having deep baritone or basso voices as a result of their large sizes, though in adaptations it of course depends on the voice actors.
  • Badass Boast: "And we shall know no fear!" is one of the most well known, but every chapter is replete with them.
  • Badass Cape: Often part of an officer's Bling of War.
  • Badass Creed: Each chapter has a Catechism of Battle, a war cry that invokes their Primarch and/or the Emperor in battle.
  • Badass Crew: Every Company, whether it's a Veteran, Battle, Reserve, or Scout Company, will be made of up to one hundred Badasses. Every squad, whether it's composed of Assault, Devastator, or Tactical Marines, will be composed of up to ten Badasses.
  • Badass Grandpa:
    • Most Space Marines will live centuries before finally being killed, and many Chapter Masters are this by default.
    • Dreadnoughts are crewed by Marines on terminal life support, which also means that they usually will have a few millennia under their belt. The oldest Dreadnought, Bjorn the Fell-Handed, is possibly the oldest living being in the Imperium, having walked alongside the Emperor at one time.
  • Badass in Charge: Chapter Masters, Captains, and Sergeants need to be this.
  • Badass Long Robe: Astartes frequently wear robes when out of their Power Armour. Some chapters wear their robes over their armor.
  • Barbarian Tribe: A good portion of Chapters including the Space Wolves, White Scars, and later on the Dark Angels are derived from this kind of culture. Justified since every Astarte initiate Had To Be Sharp.
  • Berserk Button: Two common ones are badmouthing the Emperor or the chapter's Primarch within earshot, or threatening the chapter's gene-seed. Even "nice" chapters can become decidedly unfriendly in these cases.
  • Beware the Nice Ones: Some chapters have reputations for humility or looking after noncombatants, but make no mistake, they're still some of the most dangerous forces in the setting.
  • Beware the Superman: One thing loyalist Marines agree with Horus about is that they refuse to be under the authority of the High Lords of Terra. This makes them seem untrustworthy since their way of protecting humanity sometimes clashes with conventional Imperial forces.
  • BFG: Most humans can barely hold an Astartes bolter, let alone fire one without shattering their wrists. Weapons classified as Heavy, such as lascannons and missile launchers, are even larger, almost the size of an armored Space Marine in and of themselves.
  • BFS: Power swords, chainswords, force swords - basically any blade a Space Marine wields will be large enough that a regular human could barely pick it up, much less wield it. Even the combat knives used by Scouts are almost the size of claymores in comparison.
  • Big Book of War: The Codex Astartes, which not only prescribes a chapter's force organization and markings, but includes battle tactics and strategies.
  • Big Brother Instinct: The nicer chapters towards non-combatants and the Imperial Guard, if they're pulling their weight.
  • Big Eater: Astartes can eat thrice the amount of food of a normal human. This is to fuel their hyper-metabolism due to the huge amount of genetic engineering that went into them. In addition, because food is one of the mortal comforts Astartes can enjoy, feasting is very important to them as a result, with dinner usually being a grand feast by human standards, while feasting days will hold banquets considered a feast by Astartes standards.
  • Bio-Augmentation: No single implant elevates them to Super Soldier status, but the entire process combined elevates Space Marines into gods of war even without their armor. Note that for various reasons, some chapters have lost an implant or two or have oddities in an organ or two, but all have the most essential: the Progenoids and the Black Carapace.
  • Bizarre Human Biology: As a result of the aforementioned bio-augmentation, many use the term "posthuman" to describe Astartes.
  • Bling-Bling-BANG!: Space Marine weaponry can be as elaborately and ornately decorated as their armor.
  • Bling of War: Varies by chapter, but purity seals, prayer inscriptions, shiny battle honors, animal pelts, or even solid gold plating are fairly common decorations, especially among commanders.
  • Blood Brothers: Many chapters have blood-mingling rituals, which may involve imbibing the blood of their fellow Marines - this is possibly the result of their Omophagea implant, which allows them to process Genetic Memories of biological material they consume. In this manner, the Marines share traces of memory with each other, further solidifying their bond with each other, and the blood of the fallen will be consumed that the living might better remember them. For some gene-seed strains, mutations in the Omophagea implant give them a greater thirst for blood, and their blood ceremonies are more frequent; the Blood Angels and their successors are the best known of these.
  • Boring, but Practical: The ubiquitous Rhino personnel carrier. It's not particularly well-armed or -armored, but it's so robust that it's the only transport whose driver may be able to repair if it gets immobilized by enemy fire. The Rhino's based on a tractor template that can run off almost anything, including wood or corpses, and its design is so well-made and practical that all of the Astartes' tanks aside from the Land Raider are variants on its design. In more gaming terms, Rhinos are incredibly cheap points-wise (35 for an entirely unupgraded bog-standard Rhino, with a corresponding Tactical Marine being 14 points each model) and they're also good impromptu cover for squads - AV 11 is proof against S4 or lower (it'll laugh off lasgun and bolter fire, for instance).
  • Brain–Computer Interface: The Black Carapace, one of the final augmentations a Marine receives, functions as one. It consists of semi-organic sheets implanted under the skin which take root and grow connections to his central nervous system. Ports on the outside of the Carapace stick out through the skin and form attachment points for control jacks in his Powered Armor, allowing him to control the armor as an extension of his own body. In this way Space Marines can move with much more dexterity than would be expected of such hulking armored warriors.
  • Bruiser with a Soft Center: The "nicer" chapters will refuse to abandon civilians to the enemy and can respect non-Astartes warriors they serve with.
  • Bulletproof Fashion Plate: Justified in that the majority of Marines have entire teams of serfs and servitors dedicated to scrubbing down and cleaning their armor after a deployment - they have heraldry to display, after all. The official Citadel tank painting guide recommends that weathering on Space Marine tanks be kept very slight to reflect this.
  • The Cavalry: For many of the Imperium's battles, the turning point came when the Space Marines arrived from orbit.
  • Chainsaw Good: While Space Marines have much more access to power and force weaponsnote  than other Imperial factions, they're still mainly provided to higher-ranking Marines such as Sergeants and Captains. Thus, chainswords are a common melee weapon, as well as the less common chainfistnote  and chainaxe, favored by Space Wolves. Their monomolecularly-edged adamantium teeth make short work of enemy armor.
  • Child Soldiers: Astartes are recruited as young as 10 years old.
  • Church Militant: There's a good deal of variation regarding to what extent the Space Marines consider the Emperor a deity, but the more fanatical chapters such as the Black Templars and White Consuls are true to this trope.
  • Close-Range Combatant: Though certain chapters excel at it more than others, in general Space Marines are made for shock assaults and vicious close-ranged firefights. Even their artillery is short-ranged compared to the batteries of the Imperial Guard, while the Space Marines' navy is geared toward boarding actions and planetary bombardment rather than long-ranged duels.
  • Conditioned to Accept Horror: A Space Marine's hypno-indoctrination removes their sense of Primal Fear, replacing their sense of recoiling revulsion with contempt.
  • Crazy-Prepared:
    • A lot of their Bio-Augmentation makes sense, like the secondary heart and ultra-fast clotting blood. But being able to darken your skin to resist radiation, go into suspended animation to survive near-mortal wounds, or spit a corrosive acid?
    • In terms of tactics, the Eldar in Dawn of War remind us that "you cannot ambush a Space Marine, they expect treachery at every turn. The most you can do is confirm their suspicions."
  • Crippling Overspecialization: Sometimes Scouts, Assault Marines or Devastators find themselves unable to transition to other roles.
  • Cyborg: All Space Marines due to the aforementioned Black Carapace. Beyond that, it's not uncommon for injured Astartes to have augmetic eyes or Artificial Limbs, while Techmarines usually return from their pilgrimage to Mars with various cybernetic attachments and the Iron Hands chapter makes becoming more and more mechanical a goal. This is reflected in the miniatures: unhelmeted heads w/augmetics, mechanical arms, even an upgrade kit that allows Iron Hands players to give their Marines lots of different augmetics.
  • Dark Is Not Evil: Many Space Marine chapters, such as the Raven Guard, Black Templars, and especially the Legion of the Damned and the Deathwatch, have dark-colored or black armor but are not at all "evil" by 40K setting standards. Chaplains also typically have solid black armor no matter what chapter they're in.
  • Death from Above: Space Marines arrive from orbit in Drop Ships or Drop Pods, and favor a mobile form of warfare making frequent use of airborne soldiers or Jet Packs.
  • Destructive Savior: The Space Marines can win nearly any battle they fight, but will often leave whole cities devastated in the process.
  • Determinator: "A fortress will not stop the Space Marines, although it may slow them down."
  • Divergent Character Evolution: The legions all became distinctive thanks to the influence of their Primarchs.
  • Drop Pod: A signature Marine tactic, as few foes can recover from a surprise attack that instantly puts dozens of Marines in the middle of your base camp.
  • Drop Ship:
    • The Thunderhawk gunship, equally capable of space combat, air support, Gunship Rescues, or unleashing hell upon a target before unloading its Space Marine passengers.
    • The Stormraven is a smaller but no less capable gunship, loaded to the gills with weapons and capable of delivering both a full squad of Marines and a Dreadnought into battle.
  • Drop the Hammer: Thunder Hammers are ginormous mallets wrapped in an electrical field that stuns whatever they don't pulverize.
  • Due to the Dead: The rites and rituals vary by chapter, but all at least are fanatical about recovering fallen battle-brothers' gene-seed. It gets more complicated with Dreadnoughts, which get a ritual listing their pre-interment accomplishments when reawakened, as well as a "second funeral" in the event one is destroyed. It's a little more awkward given the size of the deceased's remains and the issue of differentiating between when he was alive and when he was dead etc...
  • Elite Army: The 1st Company Task Force and Strike Force Ultra Formations allow a player to field an army composed entirely of Marines drawn from the Chapter's Veterans.
  • Fantasy Counterpart Culture: The Space Marines as a whole resemble the ancient Roman army. They increasingly recruited from barbarian planets and often became more loyal to their commanders than to some distant Emperor.
  • Fearless Fool: To live up to the "And they shall know no fear" boast, Astartes' mental conditioning leaves them biologically incapable of feeling a fear response. That said, they're not stupid; all Space Marines have the "Combat Tactics" rule that allows them to choose to fail a morale test and fall back and regroup, should the player deem it prudent. However, you can also play this trope straight and swap out this ability for another.
    • This has been played with over time. Currently, Space Marines still experience fear, but it simply does not impair their judgment in any way.
  • Feudal Future: Chapter Masters are given lordship over their chapter's homeworld and all its human or material resources, and are exempt from the Administratum's tithes but are obligated to serve the Imperium as warriors. A veritable army of human serfs perform the day-to-day tasks of food production and maintenance of the Space Marines' fortress-monastery, and can be said to be better off than other planetary populations, especially since they're living on one of the most well-defended worlds in the Imperium. On the other hand, many Space Marine chapter homeworlds are deliberately kept at a feudal or even Stone Age technology level in order to breed better warriors to recruit.
  • Genetic Memory: This is the function of the Omophagea implant, allowing Space Marines to pick up memories and experiences from something by consuming its flesh.
  • Genius Bruiser: Most Space Marines study a Big Book of War that tries to anticipate any combat situation ever, and the mainstay of any chapter is the adaptable and fluid Tactical Squad. Commanders from Sergeant rank and higher are even better, while Librarians are potent battle psykers as well as record-keepers and tactical advisers.
  • Glory Seeker: Although their indoctrination should have them feel that simply being a Space Marine is already glorious in itself, a fair number are out to make names for themselves, at least in the eyes of their Battle-Brothers. More than that, Space Marines willingly plunge into the most dangerous of missions, so that in joint operations with other Imperial forces the Astartes can come across as glory-hogs.
  • Good Is Not Nice: Remember, even the "good" chapters are ultimately working for the xenocidal fascist state that is the Imperium at large.
  • Gravity Master: Graviton weapons are an option for a Marine's armament, increasing the local gravity around the target and crushing it under its own weight. In-game, grav weapons deal more damage to targets with a 3+ or better armor save, reflecting the weapon's effects on the target's heavier armor.
  • Hand Cannon: The standard-issue Space Marine sidearm is the bolt pistol, which fires the same fully-automatic rocket-propelled armor-piercing explosive rounds as a boltgun, just at a shorter range.
  • Helmets Are Hardly Heroic: Space Marine sergeants or other commanders are often depicted without their helmets for one reason or another. Tactical Squad model kits actually enforce this; the torso bits meant for the squad's sergeant have a large collar (meant to represent the most recent version of Astartes power armor) that the helmets don't fit into very well, thus making it almost necessary to use a bare head for that figure.
  • Heroic Build:
  • Heroic Willpower: All Astartes have this in spades.
  • Hiding Behind the Language Barrier: Invoked; most chapters will use their homeworld's tongue as a battle-cant so even other Imperial forces, which will speak some variant of Gothic, won't be able to eavesdrop on sensitive transmissions.
  • Highly Conspicuous Uniform: Even the more restrained chapters may still sport a striking color scheme on their armor. Rather than attempting to disguise his position through camouflage, "a Space Marine’s armour is bright with heraldry that proclaims his devotion to his Chapter and the beloved Emperor of Mankind. [...]what the enemy can see, he will soon learn to fear...". This is slightly more justified than most examples, as in older Editions the Space Marine's armor was explicitly tough enough to be a substitute for tank armor, and sitting in a Rhino with only Marines would mean that the Rhino is no longer open-topped.
  • Honor Before Reason: Space Marines take pride in their chapter colors, and the overwhelming majority of them refuse to wear camouflage. This results in scouts of the Imperial Fists chapter trying to sneak through terrain in bright yellow armor.
  • Hope Bringer: If a member planet of the Imperium is under attack by Xenos or Chaos, every citizen will pray with fervor to the Emperor to be saved, and their prayers will be answered once the Space Marines arrive. This is especially true of the more humane chapters, like the Space Wolves, the Salamanders, the Blood Angels, the Raven Guard, and the Ultramarines.
  • Human Subspecies: Space Marines functionally become a subspecies due to the extensive changes they go through.
  • Humans Are Flawed: Astartes are supposed to be the pinnacle of human bio-engineering yet many have fallen to Chaos or otherwise misread The Emperor's goal for the human race. It's not so much because of external factors but rather their own flawed human nature.

    I - P 
  • I Gave My Word: Many chapters are oath-bound to protect or serve various worlds or agencies, and most consider keeping their word to be quite important.
  • I'm a Humanitarian: The Omophagea implant allows a Space Marine to absorb memories from the flesh they eat. The brain is generally considered the best source for this, but in some sources even drops of blood can trigger some memories. Mutations in it can give chapters an unnatural craving for blood or flesh. Ironically, most Space Marine chapters consider cannibalism depraved, since it's usually a sign of Chaos corruption, and any Marine who has to engage the Omophagea will be under scrutiny for several days by the Chaplains and Apothecaries in case something happens.
  • Immortal Procreation Clause: Space Marines are the most long lived humans in existence. They are immune to most diseases and can survive the most grievous of injuries. In exchange, their biochemical composition has been modified to make them barren so they channel all their impulses into waging war.
  • In Harm's Way: Once the battle's done, the Marines are off to the next warzone. They're often portrayed as restless when not on campaign, and garrison duties at the fortress-monastery are often considered boring.
  • Interservice Rivalry:
    • Unfortunately, Space Marines can be just as prideful as mere humans, and some chapters have developed grudges with or prejudices toward their brothers. The Ultramarines look down on those that don't embrace the Codex Astartes, while the Hammers of Dorn look down on the Ultramarines for not following the Codex strictly enough. The Red Thirst and Black Rage have given the Blood Angels and their successor chapters a dangerous reputation. Chapters of the 21st Founding are considered cursed due to ill fortunes that befell many of them. Nobody likes the Marines Malevolent. The most famous rivalry is between the Dark Angels and the Space Wolves, a grudge both chapters have maintained since their Primarchs began the feud. Older material mentions the chapters going to war on eleven occasions over objectives such as the gemstone mines of the moons of Magdalan, but nowadays it's settled by champions engaging in a (usually) non-fatal duel. Other rivalries or feuds include: White Scars vs. Raven Guardnote , White Scars vs. Space Wolvesnote , and Iron Hands vs. Raven Guard and Salamandersnote .
    • Also bleeds into how some chapters treat other organisations in the Imperium. The Guard are a useful ally but ultimately replaceable, and are fortunate if the Astartes' goals happen to coincide with theirs. The Inquisition technically has the ability to unconditionally requisition any Astartes for whatever purpose they wish but both groups generally distrust the other's independence. The Navy dislikes the fact that they operate their own separate fleets. The Ecclesiarchy (and attached military forces) don't like the fact that (most) Astartes don't view the Emperor as a God (or even deny it) but can't really do much about it. The Mechanicus are distrusted because they usually pursue their own agendas, with active members of the Titan Legions being almost the only people who equal or exceed a Marine's individual value.
  • Jack-of-All-Trades: Both Space Marines individually and their army as a whole are good at practically everything with no particular deficiencies when it comes to combat and warfare, translating into their stats being generally balanced across the board in gameplay terms. They are often seen as the best army for beginners as a result, as there is no one area where they are notably weak, other than (arguably) their lack of numbers (ameliorated somewhat by their high toughness and good armour save).
  • The Juggernaut: Land Raiders are exceptionally tough and are the hardiest tanks the Astartes have in their armories. In-game, all Land Raider variants have 16 wounds and are the only Astartes tanks with a 2+ armor save.
  • Master of All / Master of None:
    • The Space Marines straddle between these two tropes, leaning decidedly towards the former in lore and the latter in game mechanics. In lore the Space Marines are stronger, tougher, faster, smarter, more accurate, and more courageous than damn near anything else in the setting that isn't an enemy general (and sometimes even then); even one is enough to turn the tide of a battle. In-game, Space Marines are good at everything, but aren't particularly great at anything. They're outshot by almost every Aeldari faction, Imperial Guard and T'au, and outfought in close combat by Orks, Tyranids, and Daemons; they're slower than the Aeldari, and Orks and almost everyone gets cheaper (read: more) troops than them (not to mention better and shootier vehicles). The only area where they really shine is their infantry durability and for a while they were even outdone on that (by the Necrons, who have since had their armour softened a bit).
    • These tropes are personified in the Land Raider. The normal version is notorious for being a Jack-of-All-Stats / Master of None. It's very tough, it has a pair of anti-tank weapons, an anti-infantry weapon, and the ability to transport a full squad of models (or a half squad of Terminators). It can also fire its weapons at multiple targets (which, back when it was introduced, was a very unique rule). Unfortunately, it also costs a bomb and it can only fulfill one role (anti-vehicle, anti-infantry, or transport) effectively at a time; as such, the tank itself is often outdone by smaller tanks. Its major selling point, its durability, is outdone by the fact that the opponent has almost no reason to want it dead, as dedicating any firepower its way would be a massive waste of resources and the Raider itself cannot do anything valuable by simply existing. Various Land Raider variants lose the general versatility in favour of more focused weapons loadouts and/or emphasis on either being a gun-tank or a transport and are generally more useful as a result.
    • The Space Marine Tactical Squad is derided as the worst unit choice in the codex, if not the entire game. While they look good on paper, having the ability to take a special weapon and a heavy weapon normally other troop choices cannot take, and split into 2 squads to effectively use said weapon, they must pay for the extra bodies to unlock those options and lack the supplementary skills given by other dedicated units. Devastators can bring far more weapons to bear while Assault Marines can bring Eviscerators and Power Weapons to assist in combat. The worst part is, neither of those two units are any worse than Tactical Marines in the same situation. The only incentive to take Tactical marines is due to the mandatory Troops requirement.
    • Sternguards have a special rule called "Specialist Ammunition", which gives them enough firepower to deal with almost all non-vehicle units. One of the more popular upgrades for them is either a Combi-Melta or a Combi-Plasma. Both are cheap guns that have a one-use version of the non-bolter gun (Melta or Plasma) which are devastating against heavy tanks and light tanks respectively. As they still retain the use of their Specialist Ammunition, this gives a squad of them the ability to tackle almost any sort of enemy.
  • Neural Implanting: Astartes chapters typically make heavy use of hypno-indoctrination, implanting knowledge into Marines during meditation-induced fugues.
  • No One Gets Left Behind: Astartes will fight viciously to recover their fallen brothers' progenoid glands, which contain the stem cells for the implants necessary for creating the next generation of Space Marines.
  • One-Gender Race: The implants don't work on women, alright? Though if they did, given the Marines' grotesque musculature and armor it'd be hard to tell the difference.
  • One-Man Army: In the background it's said that a single Space Marine could, given time, conquer a planet by himself. The tabletop is a different story.
  • Our Angels Are Different: The Space Marines are sometimes referred to as the God Emperor's own "Angels of Death", an army of nigh-invincible superhuman warriors coming down from the heavens to protect humanity in their greatest time of need. Sometimes they recruit the mightiest warriors and heroes from feral and feudal worlds, these individuals "leaving" the world of mortals to fight for the Emperor forever. And then there's what they go through to become that way...
  • Outgrown Such Silly Superstitions: The Space Marines venerate the Emperor, build cathedrals and monasteries in his name, and pray to him for intercession of the battlefield, but as a father figure to be emulated, not a god. This can cause friction between the Astartes and the Ecclesiarchy, but in the best cases the two agree to disagree, so that the Ministorum does not excommunicate the Space Marines as heathens, and the Astartes don't use their legacy as the Emperor's descendants to usurp spiritual leadership. In the worst cases, well...
  • Pet the Dog: In numerous instances, the Astartes treat the local Imperial Guard and PDF as more than just Cannon Fodder and genuinely care about minimizing theirs and civilian casualties. A good example is Space Marine, in which Captain Titus of the Ultramarines has nothing but respect for the Imperial defenders, who in turn show nothing but admiration to their saviors.
  • Photographic Memory: The Bio-Augmentation done to the Space Marines leaves their memories as close to eidetic as possible, so they can recall potentially vital information in after-action debriefings.
  • Powered Armor: A standard Space Marine has better protection than other races' elite troops, while Terminators wear Tactical Dreadnought Armor that can carry miniguns one-handed and survive being stepped on by Titans.
  • Power Fist: The Trope Namer is a large gauntlet with an energy field running through it that makes it easily able to shatter enemy armor. It's usable by most characters, but is standard issue for Space Marine Terminators.
  • Pro-Human Transhuman: In a general sense, all Space Marines fight on behalf of Mankind despite no longer belonging to it, while the "nice" chapters show concern for the fates of the normal humans they are sworn to defend.
  • Proud Warrior Race Guy: As an analogue of medieval knightly orders, Space Marines possess a chivalry of sorts. They don't let this get in the way of genocide or xenocide, however.

    Q - Z 
  • Rage Helm: Mark VII helms. Earlier models are less angry, but no less scary.
  • Sapient Tank: A Land Raider's machine spirit is powerful and advanced enough to be able to take control of the tank if necessary, although its overall function is limited.
  • Sergeant Rock: Any Brother-Sergeant.
  • Shoulders of Doom: Those iconic huge pauldrons, proudly displaying their chapter symbol and squad markings, or the Prime Helix badge for Apothecaries. Please note that they're auto-reactive shoulder guards that can swivel as needed so not to obstruct sight or arm movement. For Terminators they're even more important, as the Crux Terminatus on their left shoulder is said to contain a sliver of the Emperor's personal armor.
  • Sigil Spam: Aside from their left pauldrons, Space Marines will slap their chapter's symbol on anything they can. The knees and cuirasses of their power armor are often decorated thusly, along with robes and tabards, banners, vehicles, and some weapons. The Ultramarines, Blood Angels, and Black Templars are especially known for this.
  • Smug Super: Some Chapters openly despise normal humans for their weakness; others are less directly smug, but are very aware of how poorly normal people measure up to an Astartes.
  • Space Marine: Be warned, Games Workshop has trademarked the words, and is not afraid to sue.
  • The Spartan Way: Take a bunch of adolescents or pre-teens, run them through a few Death Courses, with maybe some Gladiator Games at the end. Subject the survivors to mental, physical and spiritual tests that could kill them or drive them insane. Implant them with a series of Bio Augmentations that might kill them or mutate them beyond recognition. Before their training is complete, have them serve as commandos and skirmishers in the Scout Company. All said, about one in a hundred aspirants survives to don his power armor as a full Space Marine.
  • The Stoic: Many Space Marines, and some chapters more than others.
  • Straw Hypocrite: Most Astartes legions abhor assassinations, sabotage and espionage. That work gets left to Scouts. But since every Marine started as a Scout, that means the proudest Marine is knowledgeable of these less honorable aspects of warfare and might even an expert at it.
  • Super Soldier: Eight feet tall, a lifespan measured in centuries, every waking moment spent either in battle or training for it... and those are your basic Space Marines. Now consider their veterans, or commanders.
  • Super Spit: Weaponized with the Betcher's Gland, which turns a Space Marine's saliva into a blinding, corrosive poison.
  • Super Supremacist: Some Astartes get into this mindset via Might Makes Right, being vastly superior to standard humans in every way and thus asking why they should fight and die for them. Falling to Chaos is not the inevitable outcome, but it's a common fate.
  • Super Toughness: As a result of their Bio Augmentations. Most armies' standard weapons only have a 50% chance at best of wounding a Space Marine.
  • Sword and Gun: A paired bolt, grav, or plasma pistol and chainsword is a very common baseline weapons kit for Space Marines, especially Assault Marines. In-game, this combination allows for one extra attack in the combat phase.
  • Take Up My Sword: Space Marine equipment is so well-built and lovingly-maintained that many pieces have been passed down from Battle-Brother to Battle-Brother for centuries, if not millennia. There are often elaborate rites and rituals surrounding this practice, which can involve engraving the accomplishments of the previous bearer of a piece of kit, or adding decorative reliefs. As each piece is further passed down, these become increasingly elaborate and valuable to the chapter.
  • Tank Goodness: The Land Raider again, eclipsing the Predator dedicated battle tank, which tends to look a little underpowered when compared to the Imperial Guard's vehicle pool.
  • Terrifying Rescuer: Depends on which chapter comes to save the day. The Salamanders look scary but are very much good guys, while God-Emperor help you if the Flesh Tearers or Marines Malevolent are the ones to try and help.
  • True Companions: For all the setting's moral ambiguity, this is one virtue that the Space Marines generally espouse and embrace. From day one of training, they are taught the value of working with their Battle-Brothers, and due to sharing the blood of the same Primarch and growing up together during training, this is the closest to family the Astartes have. Personality clashes, rivalries, and other sources of friction happen just like in any other group of people, but in general the need for the companionship of fellow Astartes is one of the few psychological weaknesses Space Marines have.
  • Unbreakable Bones: The Astartes' bones contain ceramite due to a combination of the Ossmodula's function and their food being laced with ceramite-based chemicals, making them far, far harder to break than normal.
  • Undying Loyalty: To their Primarchs. This is sometimes a Fatal Flaw, even to the loyalist legions like the Space Wolves.
  • Warrior Monk: Super soldiers who train and dwell in fortress-monasteries, holding nigh-unshakeable faith in their role as The Emperor's favored champions (Most of them however, in spite of their zeal and devotion, do not regard him as a god though).
  • Weirdness Coupon: Many chapters don't consider the Emperor a god, have rituals and traditions that would be considered heretical by the Ecclesiarchy, or exhibit genetic deviancy beyond what is normal for Astartes, but are nevertheless tolerated by Imperial authorities due to the Space Marines' necessity. The First Founding chapters and their older direct descendants (especially the Second Founding ones) tend to be given more leeway than younger chapters, of course.
  • Wolverine Claws: Lightning Claws are power weapons with three or four claws attached to a Power Fist, very popular among Terminators in general and the Raven Guard in particular. The Space Wolves' variant are of course called Wolf Claws.
  • The Worf Effect: Due to the Astartes' toughness, new threats are often expressed in terms of how many Space Marines they killed. The Tyranids, for example, are introduced by wiping out the Ultramarines' 1st company and nearly overrunning their homeworld, while the Necrons are shown coring Land Raiders with their Gauss weapons.
  • Would Not Shoot a Civilian: Many chapters would prefer not to; others aren't concerned with notions of collateral damage.


Astartes Command


"A Captain leads from the front. By his example shall his men know what it is to be of the Adeptus Astartes, and from his teachings shall they learn the trade of battle in the Emperor's name. No ordinary man can a Captain be, for many are the paths to victory and he must be master of them all. His very being shall be an extension of the Emperor's work. With every strike of his sword, with every word of his speech, does he reaffirm the ideals of our honored master. He will vanquish darkness and heresy with every thought, word, and deed. So shall his coming be a sign of deliverance to the dutiful, and a herald of dismay to all traitors. No living man shall stay his wrath."
Roboute Guilliman, from the Apocrypha of Skaros

Those who command the Angels of Death are not only great warriors but also brilliant strategists with centuries of experience fighting the enemies of the Imperium.

The Chapter Master is the most senior Captain in the Chapter, at once one of the Chapter's most experienced warriors and among the most gifted military leaders in the Imperium.

A Space Marine Captain (also known as Brother-Captain) typically commands an entire company of his battle brothers (a customary maximum of one hundred Marines). In addition to his duties as the leader of a Space Marine Company, each Space Marine Captain also bears one or more honorific titles which may also carry additional responsibilities extending to the entire chapter. Similar titles are also bestowed on other officers of specialized units, such as vehicle commanders or leading Chaplains. Some of these titles are commonly used across all Space Marine Chapters, while others are unique products of a single Chapter's history and creed.

After his return, Roboute Guilliman’s rewritten Codex Astartes added the rank of Lieutenant to the Astartes Order of Battle. Each Company includes a pair of Lieutenants who each take command of a Demi-Company so that the Captain can concentrate on overseeing the entire battlefield.

  • An Axe to Grind: The model for the 8th Company Captain wields a large double-headed power axe.
  • Authority Equals Asskicking: The leaders of Space Marine companies and typically their best fighters, and the Chapter Masters are usually the best fighters in their entire chapter, with some exceptions.
  • Bodyguarding a Badass: Space Marine Commanders are highly skilled combatants yet are often accompanied to the battlefield by squads of bodyguards of Company Veterans or Honour Guards.
  • The Captain: Each company is lead by a Brother-Captain, who also usually holds some sort of logistical position within the Chapter (such as Master of the Arsenal, Fleet, Recruits, etc).
  • Frontline General: While they may often take command of entire war zones, a Space Marine Commander will still lead the most important missions personally, inspiring his battle-brothers with his presence.
  • Four-Star Badass: Those who command Astartes on the battlefield typically possess centuries of experience fighting the Emperor's foes.
  • The Leader: Captains are the senior-most leadership of an Astartes chapter, with only the Chapter Master ranking higher.
  • Number Two:
    • A Chapter Master's second-in-command and designated successor is usually the First Captain, the Captain of the First Company and the most senior Captain in the chapter.
    • Within a Company, Lieutenants act as the second to their Captain, sharing the burden of commanding the battle-brothers of the Company across multiple engagements.
  • Orbital Bombardment: In previous editions of the game, a Chapter Master could call down an Orbital Strike attack, dropping a powerful large blast shot representing a shot from one of the massive gun emplacements on the Chapter's ships in orbit around the planet. In 8th Edition, this ability is a Stratagem available to all Space Marine armies from a Codex-compliant Chapter, no matter who commands them.



"Death or healing, I care not which you seek!"
— An Apothecary in Dawn of War

Apothecaries are Space Marines with special medical training. Their role in battle is to recover the Chapter's gene-seed from slain Marines and to tend to the wounded. Outside of combat, Apothecaries are responsible for monitoring recruits and neophytes for mutation or flaws in their gene-seed organs and implants.

The insignia of the Apothecaries is the prime helix, a stylized DNA strand rendered in bright red and sometimes adorned with additional iconography such as wings and skulls. The symbol represents the sacred code of the Chapter's gene-seed. Also, Apothecaries of most Chapters wear partially or completely white power armor, with the left pauldron retaining their Chapter's colors and symbol and the right pauldron displaying the prime helix. Some less traditional Chapters use different schemes. Apothecaries also use the narthecium, a large gauntlet-mounted multi-tool.

The Master of the Apothecarion or Chief Apothecary is the senior-most Apothecary in a Space Marine Chapter. As head of the Apothecarion, the Master of the Apothecarion is responsible for assigning Apothecaries to Companies, so that they may heal their battle-brothers or recover the gene-seed.

  • Color-Coded for Your Convenience: Apothecary armor is at the very least white on the right pauldron, and is sometimes completely white, with the prime helix in red.
  • Combat Medic: The battlefields of the 41st Millennium are no place for pacifist medics, and Apothecaries are just as capable in combat as any other Astartes. They don't actually get to do that much battlefield medicine, since a Space Marine's physiology means that almost any injury sustained in field that would take a Marine out of combat for very long is likely to be fatal, so the Apothecary simply makes the process less painful. The Apothecary's more important duty is ripping open his fallen brothers to harvest their gene-seed.
  • Mercy Kill: "The Emperor's peace", usually delivered via a bolt round to the skull or the Carnifex device in the narthecium.


At battle's end, speak the Liturgy in a clear voice. Respect the bravery of the living. Give the Rite of Passage to the fallen. Honour the battle gear of the dead. To do all this with reverence, even when exhausted by battle and weary from the field, is the duty of a Chaplain. It is his burden and satisfaction.

Chaplains are the spiritual leaders of Space Marine Chapters: warrior-priests who fight alongside their battle-brothers, chanting the Chapter's sacred battle creeds and inspiring their brethren to greater feats of bravery. To enemies they appear as terrifying and sinister figures in black power armor and skull-visaged helmets.

  • Ancestral Weapon: The power armor suits worn by Chaplains are considered holy in themselves. Often they are hundreds, if not thousands, of years old.
  • Carry a Big Stick: The Weapon of Choice of the Chaplains is the Crozius Arcanum, essentially a scepter that is as much a badge of office as it is a power weapon for bashing heads in.
  • Death from Above: Chaplains sometimes join Assault squads, using jump packs for aerial attacks.
  • High Priest: The Master of Sanctity or High Chaplain is the head of the Chaplaincy in an Adeptus Astartes Chapter and head of the Chapter Cult.
  • The Mentor: Chaplains are present in a Marine's life from the moment he is chosen as a neophyte, presiding over their indoctrination as they progress toward becoming full battle-brothers.
  • Rousing Speech: A Chaplain's specialty is to rouse a chapter to battle using only their words.
  • Staff of Authority: The Crozius Arcanum serves as a Chaplain's sacred staff of office.


"And within each company, the mightiest warrior shall be anointed as Champion. He shall bear arms and armour of great craftsmanship, and he shall protect his Captain from all harm, though it cost him his life. Great honour shall be bestowed upon him in life and in death, and he shall be lauded with great praise."
Roboute Guilliman, from the Apocrypha of Skaros

A Champion is the greatest warrior of his Company or Chapter and can be seen fighting in the fiercest of battles. They are armed with relics of the Chapter and are responsible for defending the honour of their battle brothers both on and off the battlefield.

  • The Champion: Champions are tasked with defeating the most skilled enemy on the battlefield and take part in ritual duels with those who have dishonoured their Company or Chapter.
  • Dual Wielding: Chapter Champions typically wield a pair of power weapons, giving him extra attacks when fighting his enemies in melee.
  • Duel to the Death: Champions are willing to lay down their lives in defence of their brothers and in battle they are ready to face the challenges of any enemy in single combat with all their training focused on this singular duty.
  • Master Swordsman: Champions are often the greatest swordsmen of their Company with the greatest amongst them being the Chapter Champion.
  • Sword and Gun: A Company Champion's typical weapons loadout is a power sword and bolt pistol, with a combat shield on his gun arm.


"I can pulp your flesh and snap your bones in less than a second, and without so much as lifting a finger. What is the power of technology compared to that?"
Vel'cona, Salamanders Chief Librarian

Librarians are Space Marine psykers. They fulfill several important specialist roles in a Chapter and are among the most knowledgeable of the Chapter's history and traditions. In battle they utilize their abilities to provide Warp-based attacks or to bolster themselves and the Marines around them.

The Librarian training schemes were created by Magnus the Red, a powerful psyker in his own right, along with Sanguinius and Jaghatai Khan, although some of the Primarchs were completely against using psykers in the Space Marine Legions, most notably Leman Russ, Corax and Mortarion.

  • All of the Other Reindeer: Zig-zagged. Astartes are taught to hate the deviant and abnormal, particularly mutants and those with psychic powers. Thus, for most chapters the well-deserved respect and loyalty Librarians receive from their battle brothers is mixed with, at best, wariness and mistrust. However, some chapters greatly revere their Librarians, such as the Blood Ravens and Silver Skulls, and the Blood Angels seem to respect their Librarians enough to allow them to be interred in their unique Furioso Dreadnought chassis.
  • Anti-Magic: A Librarian's armor incorporates a Psychic Hood, a device containing psychically-nullifying crystals which provide defence against enemy psychic attacks. In-game, a psychic hood gives a Librarian +1 to his Deny the Witch tests.
  • The Archmage: A chapter's Chief Librarian is the most skilled and battle-hardened Librarian in a chapter, the head of the chapter's Librarium, and one of the Chapter Master's closest advisers.
  • Badass Bureaucrat: Among the skills Librarians learn is writing and evaluating battle reports. This makes them excellent strategists.
  • Badass Bookworm: Librarians are generally the most scholarly and well-read members of a Chapter, and often serve in both research and teaching functions alongside their record-keeping role.
  • Blessed with Suck: While a Librarian's psyker ability has many benefits for himself and for the chapter as a whole, it also creates a gulf between he and his fellow Astartes, and touching the Warp is never a pleasant experience.
    Chief Librarian Tigurius: It cannot be considered a gift, to peer into the Warp and unravel the possibilities of the future that are, that might be, and that must be prevented. Nor can the burden of a weapon, that each of my brothers looks upon with girded revulsion, be called a gift. No, Master, I do not think my psychic prowess a gift...but a tool. Whether by a quirk of fate, or the will of the Emperor, I possess a weapon the like of which can turn the tide, not just in a battle but in the course of history. To withhold it, to flinch from its use or deny it would not just be counter-productive, it would be heresy. But if it is a gift, it is a cruel one.
  • Color-Coded for Your Convenience: The Codex Astartes dictates that the armor of Librarians is blue with gold and yellow highlights, regardless of chapter colors, along with a gold or yellow tabard. Good luck getting a Space Wolf Rune Priest to pay attention to that, though.
  • Communications Officer: Off the battlefield they are responsible for interstellar psychic communications. More commonly, their abilities are used over shorter distances, coordinating attacks and battle orders.
  • Dishing Out Dirt: The Geokinesis discipline involves, among other things, manipulating the ground and earth itself.
  • Military Mage: Fitting for their role as the Magic Knight, Librarians have a variety of ways to use their powers in combat, either to give boosts to themselves or units around them or to smite or hamper the enemy.
  • Order Reborn: The Emperor disbanded the corps of Librarians but they were kept out of necessity when the Horus Heresy broke out. Without him to enforce things, the Librarians have become standard part of Astartes hierarchy ever since.
  • Shock and Awe: The Fulmination psychic discipline from the 7th edition rules, developed by Space Marine Librarians, was based on Biomancy that focused solely on the lightning.
  • Spell Blade: Librarians use force weapons for melee combat, which can be imbued with Warp energy to make them even more dangerous in battle. While staves are commonly used, force axes are another popular option.
  • Sphere of Destruction: Implied in-game by Nova psychic powers from the 6th and 7th edition rules, which potentially affected everything within a certain distance of the Librarian.
  • Unpredictable Results: Although Librarians have immensely strong wills and great skill in manipulating the Warp, they're still mortal and failure is still possible, which can lead to horrible results if it goes badly enough. In-game, this is represented by psychic powers needing to meet or beat their casting cost on 2D6 to be successfully cast, and by the Perils of the Warp rule, which occurs if the player's roll to cast a power is a 2 or a 12. Perils causes the psyker to immediately suffer D3 mortal wounds, and if this kills the psyker, all units within 6" suffer D3 mortal wounds.
  • Wizarding School: Librarian aspirants are trained at a Librarium.


"Yours is to heed the machine as others heed their kin. Tend to the war spirits all about, but do so in the knowledge that you do the Emperor’s duty. Without your ministrations, no bolt may be fired, and no enemy slain."
— Extract from the Apocrypha of Eons, Verse III, Chapter CIV

Equal parts priests and mechanics, the Techmarines are cyborg Astartes responsible for keeping their chapter’s equipment and vehicles running smoothly. Since only the priests of the Adeptus Mechanicus are allowed to know the secrets of Imperial technology, prospective Astartes with an affinity for machines are picked out by their chapters and sent to Mars, where they spend thirty years learning the mysteries of the Machine Cult, and all the rituals and religious practices associated with keeping Imperial technology going. Once their studies are done, they’re ordained, technically becoming members of the Adeptus Mechanicus, and return to their chapters.

Techmarines are easy to spot, thanks to their numerous mechanical limbs. They also usually have elaborately plated, heavily mechanized armor in the rust-red of the Machine Cult, although one pauldron retains their chapter’s color(s) and badge so as not to offend their armor’s machine spirit. The highest-ranking Techmarine in a chapter is known as the Master of the Forge.

  • All of the Other Reindeer: Techmarines get this from both sides of the fence.
    • Their fellow Astartes tend to show them the same mix of respect and distrust that Librarians get, although in their case, it's usually due to personality and behavior changes caused by their augmetics and their loyalties being divided between the chapter and the Mechanicus. On the other hand, the more augmetics-focused chapters, such as the Iron Hands and their successors, greatly revere their Techmarines.
    • While Techmarines are fully indoctrinated into the Machine Cult, many tech-priests look down on them, at best seeing them as lowly cogs in the Mechanicus' overall operations and at worst treating them as Hereteks who pervert the machine spirits of their mechanical charges to wage war.
  • Artificial Limbs: Their armor is modified to include these, including both standard mechadendrites and large servo arms with multiple tools (and weapons) attached.
  • An Axe to Grind: Their preferred weapon is a Power Axe bearing the symbol of the Mechanicus. It’s ubiquitous enough to pull double duty as a symbol of rank.
  • Cargo Cult: Like the rest of the Adeptus Mechanicus, they literally worship technology that they don’t fully understand.
  • Color-Coded for Your Convenience: In most chapters, Techmarines display their additional ties to the Mechanicus by wearing dark red armor bearing the distinctive black-and-white skull cog icon of the Machine Cult. Some chapters' Techmarines wear completely red armor, similar to Librarians, while some simply have red accents and Mechanicus iconography alongside the usual chapter heraldry.
  • Combat Tentacles: The servo-arms on a Techmarine's servo-harness often bear weapons, allowing them to contribute in frontline combat while working to keep tanks and artillery repaired. In-game, the standard Techmarine can be upgraded to have a servo-harness that comes with a flamer and plasma cutter (a pistol-range plasma weapon), while the Techmarine that accompanies a Thunderfire Cannon bears a flamer, plasma cutter, and servo-arms holding shells for the Thunderfire Cannon on his servo-harness.
  • Cyborg: The Techmarines' most distinguishing features are their numerous augmetics and mechanical limbs, many of which they obtain during their training on Mars.
  • Drop the Hammer: Space Wolf Iron Priests forgo the Mechanicus power axe in favor of a thunder hammer.
  • Electronic Eyes: Even more common among the Techmarines than in the Imperium at large, due to the Mechanicus doctrine of “improving” oneself.
  • Machine Empathy: Techmarines are expected to be able to “feel” what is wrong with any given machine, and how to fix/heal it.
  • Mr. Fixit: This is the ideal to which Techmarines hold themselves: to be able to fix any problem in any machine in any situation. They tend to come pretty darn close to it, too.
  • Multi-Armed and Dangerous: Due to the aforementioned Artificial Limbs.


    Battleline Squads 
The bulk of the fighting forces that make up a Codex Space Marine Chapter consist of battleline squads with such units making up the majority of the Chapter's four Battle Companies, and the entirety of two of the four Reserve Companies. These squads are incredibly versatile units, capable of both offensive and defensive actions at a variety of ranges. A Chapter's battleline squads typically consist of Astartes Tactical Squads and Primaris Intercessor Squads.

Tactical Marines
"Of the Tactical Space Marine, bedrock of his Chapter and paragon to his brothers, I shall tell thee. He shall be steeped in the lore of battle and schooled in all manner of weapon and strategy. With combat blade, boltgun and grenade he shall assail the foe. But these are mere tools: a Tactical Marine's true weapons are his courage, his wits, and his dedication to his brothers. He will bring his foe to battle in a manner and time of his choosing, never himself caught unready or ill-prepared for the task at hand. In defence he shall be stalwart as the mountain, a bulwark stood firm against the enemies of Man. In attack he shall strike with the wrath of the Immortal Emperor, felling the foe without mercy, remorse or fear."
Roboute Guilliman, from the Apocrypha of Skaros

The solid backbone of most Astartes forces since the inception of the Codex Astartes, the Tactical Squad is a highly flexible force that can be equipped to fulfil a number of different battlefield roles.

  • Let's Split Up, Gang: A full squad consists of 10 Marines, with the option to split the squad into two 5-man Combat Squads. While all Marine types can do this, it's most commonly done by Tactical Marines, especially for means of delivering a heavy weapon such as a lascannon or missile launcher to a spot where that Combat Squad can provide fire support while the other Combat Squad ranges on for more mobile fighting.
  • Master of All: Tactical Marines are known for their mastery of war, having served in both Devastator and Assault squads prior.
  • Series Mascot: When people think Space Marines, they are thinking of the Tactical Squads, as they are by far the most commonly depicted.

Intercessor Squads

See the Primaris Space Marine Character Page.

    Close Support Squads 
Fast and aggressive units, close support squads are tasked with shattering enemy battlelines with highly coordinated and vicious assaults. Close support squads typically make up a quarter of the units in a Chapter's Battle Company while the entirety of the 8th Reserve Company consists of such squads. Assault squads and Assault Centurions are the most common types of close support squads along with light vehicles such as Bikes and Land Speeders. Primaris close support units consist of Inceptor and Reiver Squads.

Assault Marines

"And of the Assault Marine so do I decree: He shall descend upon the perfidious foe as an Angel of Judgment from on high. Let the jump pack be his wings, and the roar of its engines a hymn of retribution. Let the chainsword be his sceptre of decree, its harsh voice singing joyfully with each and every blow. With it shall the Assault Marine bring bloody retribution to the heretic, the traitor, and all alien aggressors who trespass on the Emperor's domain. So will the Assault Marine be the hunter of warlords and the slayer of kings. His armour shall run slick with the life-blood of the vanquished, and all shall honour his name."
Roboute Guilliman, from the Apocrypha of Skaros

An Assault Squad is a Space Marine unit that excels at close combat. Marines are commonly assigned to Assault Squads after exemplary service in a Devastator Squad, where they have garnered experience in holding their ground against any foe. As an Assault Marine, they must not only prove themselves in close combat, but learn other vital skills, such as the operation and maintenance of Space Marine Bikes and Land Speeders. Assault Squads are used for a variety of roles; reconnaissance-in-force, decapitation strikes, and counter-assault missions are common assignments for Assault Squads.

  • Close-Range Combatant: Assault Squads are equipped solely for close combat with pistols and chainswords.
  • Dynamic Entry: Assault Marines often find that hundreds of pounds of armored Astartes is an effective weapon in itself. Even when they're not leaping on foes from on high, Assault Marines will trigger their boosters to smash into enemies when charging across open ground.
  • Hot-Blooded: Assault Marines lust for battle after years or even decades of avoiding close combat in Scout or Devastator squads.
  • Jet Pack: Assault Marines are notable for wearing jump packs to deliver Death from Above.
  • Kill It with Fire: Assault squads have an advantage over Tactical squads in that they can take two flamers instead of just one, which can be very problematic for lightly armored foes.
  • Lightning Bruiser: Big armored men with jump packs who can storm in, kill everything and make their getaway before anyone knows what hit them.


The Astartes deploy squads of bike mounted Marines for fast-attack operations, using speed, manoeuvrability and surprise to engage enemy formations and then withdrawing before the foe can react to the sudden assault. All Marines are trained in the use of the rugged and powerful Space Marine Bike during their time as a Scout and once they become a full battle-brother, those who serve as Assault Marines and the entirety of a Codex Chapter's 6th Reserve Company can be deployed as Bikers.

  • Badass Biker: Space Marine Bikes are just as overbuilt and tough as their riders, described as navigating concrete walls by crashing through them.
  • Car Fu: Space Marine Bikers are known to use the speed, weight and momentum of their heavily reinforced mounts to pulp the flesh of their enemy when they assault their foe. In some editions this is represented by the Biker gaining a special attack on the turn that they charge.
  • Cool Sidecar: Attack Bikes are Space Marine Bikes fitted with a sturdy sidecar that sports a heavy weapon such as a heavy bolter or multi-melt, turning the Bike into a capable mobile weapons platform.

Land Speeders

Fast and agile anti-grav vehicles, the Land Speeder fulfils a number of battlefield roles from armed reconnaissance to seek-and-destroy missions. All Space Marines learn how to pilot a Land Speeder during their time in the Chapter's close support squads with the most talented battle-brothers able to pull off incredibly intricate high-speed manoeuvres at dangerously low altitudes.

  • Fragile Speedster: While the Land Speeder has the highest speed of any Astartes vehicle that isn't an aircraft they are also having the lowest Toughness and Wounds characteristics of the Space Marine vehicle pool.
  • Hover Tank: Land Speeders are the most common form of armoured anti-grav vehicle utilised by the Chapters of the Adeptus Astartes. The grav-drives of a Land Speeder aren't powerful enough for high altitude operations but they are capable of lifting the vehicle over most terrain and obstacles while still retaining a high degree of manoeuvrability
  • Target Spotter: Land Speeders often act as spotters for Whirlwinds and other artillery units, using their speed and manoeuvrability to scout out enemy positions before relaying their positions to their allies. During 7th Edition this was represented by the Suppression Force Formation that teamed a Land Speeder with a pair of Whirlwinds, while 8th Edition has the Datalink Telemetry Stratagem that increases the accuracy of Whirlwinds firing at targets visible to a nearby Land Speeder.

Inceptor Squads

See the Primaris Marine Character Page.

Reiver Squads

See the Primaris Marine Character Page.

    Fire Support Squads 

Fire Support squads provide covering fire for their battle-brothers, engaging the enemy at range to suppress infantry and to take out priority targets such as commanders or heavy armour. Roughly a quarter of a Battle Company's fighting strength will be made up of fire support squads while the 9th Reserve Company is made up entirely of such units. The fire support squads utilised by the Adeptus Astartes are generally fielded as Devastator and Devastator Centurion squads while the Primaris Marines are formed into Hellblaster and Aggressor fire support squads.


"A Devastator's reach shall be without limit and his touch without mercy. Fire shall roar from his fingertips, but it shall consume him not. Thunder will roar when he calls, yet it will swallow him not. Let the Devastator squad be thy blazing wrath, bringing the light of the Emperor's justice to the darkest corners of the battlefield. Wherever he stands, that shall be his fortress of righteousness. He shall hold in his gift the fate of all who pass before his unblinking gaze. All shall fear him, and he shall fear no one."
Roboute Guilliman, from the Apocrypha of Skaros

Devastator Squads are specialized Space Marine squads tasked with long-range fire support, and are often composed of recent promotees from Scout squads. Though veterans of dozens, even hundreds, of campaigns, service in a Devastator Squad will be their first experience in power armor as part of the main Space Marine army. Those newly-appointed to a Squad, armed only with basic gear, are given the primary duty of providing close support and calling out targets for their more experienced battle-brothers. These Space Marines are armed with the squad's six types of heavy weapons, an honor earned only after the Marine has proven himself steady and dependable in the heat of battle.

  • BFG: Using these in battle is a Devastator Squad's main purpose. They commonly wield heavy bolters, lascannons, plasma cannons, multi-meltas, grav cannons, and missile launchers, long-ranged and powerful weapons which are utilized easily enough from an entrenched location but are not easily man-portable and would hamper the movement of a Tactical squad to tote around. In-game, this is reflected by such weapons having the Heavy stat, meaning that the bearer takes a -1 penalty to his Ballistic Skill if he moves before firing.
  • Long-Range Fighter: Devastator Marines are equipped with heavy weapons to act as long ranged battlefield support for their brethren.

Hellblaster Squads

See the Primaris Marine Character Page.

Aggressor Squads

    Multirole Squads 


"Hear me out. A Space Marine...inside...of a Space Marine!"
Games Workshop CEO, Inside Games Workshop

Centurions are a type of Space Marine heavy infantry equipped with Centurion Armour. They are purposed as either Assault or Devastator types and are used for attacking enemy strongholds or bringing heavy weapons into places where a tank might not be able to easily maneuver.

  • Chest Blaster: Both types of Centurion Armor have weapons built into their chests for even more attacking power. Hurricane bolters are a standard option, but Assault Centurions can opt for grenade launchers to take care of enemy infantry and Devastator Centurions can take missile launchers for a longer range attack.
  • Meta Mecha: Centurion armor is essentially a huge, unwieldy suit of Power Armor wrapped around the pilot's normal Power Armor and loaded down with either terrifying amounts of firepower or tank- and building-shredding drills with built-in flamethrowers or meltaguns.
  • Mighty Glacier: Devastator Centurions are deployed for missions that require Space Marines to bring exceptional levels of firepower, such as siege warfare or bringing the firepower of a tank into confined quarters. Their only real weakness is their lack of speed, and they are easily outpaced by fast-moving foes. Thus, they are primarily employed to besiege defended enemy positions or to defend their own fortifications, or used as mobile firebases to strengthen the advancing battle line.
  • Siege Engines: Centurions are brutal specialist weapons tactically deployed as line breakers and besiegers, where haste is less important than durability.
  • This Is a Drill: Assault Centurions have large grinding drills on their arms to tear into enemy fortifications.


"Forget all your preconceptions of war, of battle-lines clashing in the churned ground. Your mission is to attack before the foe even realises that the war has begun, to strike hard at those vital weaknesses that all armies possess, but that no commander will admit to. Under my tutelage you will learn how to seek out such fragilities and smite them with every weapon at your disposal. Master these duties and I will have nothing more to teach, and you will truly be a Space Marine."
Sergeant Torias Telion, Ultramarines 10th Company

Once a Space Marine initiate has received most of the organs that creates a Marine and has advanced far enough in his training to begin frontline combat, he will become a Scout. The Codex Astartes stipulates that the 10th company of a chapter be a dedicated Scout company, and it is here that a chapter's Scouts are organized, armed, and trained under the command of the Master of the Recruits.

Because Scouts do not have the full complement of organs (most specifically the Black Carapace), they must use lighter armor than full Astartes, and their weapons tend to be less powerful as a result. Thus, Scouts are primarily used as infiltrators and assassins, gathering intelligence, sabotaging enemy positions, sniping leaders, and generally causing as much chaos and disruption as possible.

  • Badass Normal: Scouts are this in comparison to Astartes, as they haven't received the full regimen of organs that creates a Marine, and their Scout-type carapace armor isn't as strong as normal power armor. Still, they are deadly opponents and can more than hold their own in combat. Averted by some Chapters on principle and other chapters by circumstance. The Space Wolves only put their experienced veterans into the scouts, whilst other chapters pragmatically deploy their most talented marines into the scout companies to train a dedicated covert force.
  • Cold Sniper: Scouts are the only ones who get armed with a Sniper Rifle for long distance strikes against enemy commanders and other important targets. For a full fledged Brother to do this would be considered dishonorable.
  • Combat Pragmatist: Scouts are responsible for the Chapter's covert operations.
  • Jack-of-All-Trades: Scouts perform all sorts of battle support but they're not as flexible as Tactical marines, as good in close combat as Assault marines or as precise with heavy weapons as Devastators.
  • Overshadowed by Awesome: Scouts could give Delta Force or Seal Team Six a run for their money. Alas, it is their armored brothers that get all the press.
  • Shotguns Are Just Better: Some of them are of this opinion; and besides, only Scouts are issued shotguns.
  • Stealth Expert: Scouts frequently wear an Invisibility Cloak made of a material called cameoline which mimics the surroundings.



Terminators are veteran Space Marines who have earned the right to wear suits of Tactical Dreadnought armor, more commonly known as Terminator armor, into battle. This armor, while bulky and cumbersome, is extremely tough and can shrug off firepower that would tear through normally armored Astartes, and can be used to wield powerful weapons that normally would not be man-portable.

  • Awesome, but Impractical: Originally, Terminator Armor was meant to replace the regular kind as the legions’ main battle plate due to its better armor, firepower, and usefulness in the shock-and-awe tactics the Space Marines favor. This didn’t happen, due to Terminator Armor being very heavy and unwieldy, extremely maintenance-intensive and expensive to make, and vulnerable against Marines in regular, nimbler armor.
  • Backpack Cannon: The Cyclone Missile launcher can be mounted on a Terminator's back.
  • Boarding Party: Terminators are often tasked to board and investigate space hulks, their teleporters and chainfists allowing them to move about as needed and their suits and weapons being able to take on whatever might be lurking around, from Orks to Genestealers to daemons.
  • Creepy Cool Crosses: The Crux Terminatus, a cross-shaped icon with a skull motif, often with crossed bones behind the skull. Worn by Veterans in general, it's mounted on the left pauldron of Terminator armor and sometimes on one knee as well. It's one of the most revered icons in a Space Marine chapter, partly because of the significance of having the honor of wearing it and partly because the Cruxes worn by Terminator Captains are rumored to contain a tiny sliver of the Emperor's personal armor. The loss or destruction of a Crux is seen as deeply shameful.
  • Drop the Hammer: Some Terminators carry Thunderhammers, power weapons whose power field, instead of being spread out along a blade, is concentrated on the hammer’s head and energizes on contact in a devastating concussive blast. Regular, armored Marines need two hands to wield these things, but Terminators swing them about one-handed.
  • Dungeon Bypass: Terminators are specifically designed for such tactics (primarily space boarding actions) - they have teleporters to get past the enemy lines, the heaviest armor to keep them alive when away from support, and power fists and chainfists to make their own door whenever needed.
  • Gatling Good: Assault cannons (multi-barrelled rotary autocannons normally mounted on tanks, flyers, and Dreadnoughts), can be one-handed by Terminators as a heavy weapons option.
  • The Juggernaut:
    • Terminators are Nigh Invulnerable thanks to their heavy armor, which though relatively cumbersome allows them to stroll through firefights that would give even normal Power Armor pause. In-game, Terminator armor gives a 2+ armor save and the Crux Terminatus adds a 5++ invulnerable save, much better than a normal Marine's sole 3+ armor save.
    • Terminators in assault squads armed with a Thunder Hammer and Storm Shield take this even further, as the Storm Shield bumps their invul save to 3++. This combo gives them a level of protection virtually unrivaled by any non-character model anywhere else in the game (as a reference, these guys get the same save against armour-piercing anti-tank lasers as a normal Space Marine gets against small arms fire). Accordingly, they are considered one of the best, if not the best close combat units in the game.
  • Luckily, My Shield Will Protect Me: Most of the time the Storm Shields of the assault squads will protect them. It gives them a 3++ against everything, so the only reliable way to kill a squad using them is direct a massive amount of gunfire at them so their saves eventually fail.
  • Mighty Glacier: Terminator armor is much slower and more cumbersome than the regular variety. On the other hand, it carries much heavier weaponry and is so durable that a Marine wearing it can survive being stepped on by a Titan.
  • More Dakka: In comparison to normal Astartes. Not only can Terminators field assault cannons and Cyclone Missile launchers, a storm bolter is their standard sidearm, essentially doubling their default firepower. In-game, storm bolters put out two shots to a normal boltgun's one shot.
  • Overshadowed by Awesome: The regular Terminator squads don't see much use because most players will use the Assault Squads for the save granted by their Storm Shields.
  • Praetorian Guard: In previous editions it was possible to take Terminator Command Squads, either as upgrades to a regular Terminator Squad or as a separate choice entirely, to represent the Command Squad of the 1st Company. In 2016 a Terminator Command Squad model kit was released.
  • Teleporters and Transporters: Terminator armor is equipped with teleporters, allowing the Marines to strategically insert themselves into battles. In-game, Terminator units that aren't in transports can choose to teleport into combat as long as they're more than 9" away from enemy units, and can field a teleport homer for more strategic teleporting.

    Sternguard & Vanguard Veterans

Few Chapters have the resources to equip all their Veterans with suits of Terminator Armour, and so the rest of the 1st Company will take to the battlefield in Power Armour as either Sternguard or Vanguard squads depending on their speciality. Sternguard Veterans are experts at ranged combat, supporting their less experienced battle brothers with pinpoint fire and superior weaponry, and providing covering fire when a Chapter is forced into a fighting retreat. Vanguard Veterans on the other hand specialise in close combat and can be found spearheading the charge into enemy lines.

  • Abnormal Ammo: Sternguard Veterans can upgrade their bolt weapons with Special Issue Ammunition, a variety of specialized bolt rounds such as the long range Kraken bolts or the armour piercing but highly unstable Vengeance rounds.
  • BFS: Vanguard Veteran Sergeants are sometimes honoured with a relic blade, a two-handed power weapon of masterful craftsmanship.
  • Continuity Nod: Two of the bare heads from the Sternguard Veterans (specifically these two) are clearly based on Captain Titus and Sergeant Sidonus from the Warhammer 40,000: Space Marine video game.
  • Creepy Cool Crosses: Although they rarely have them moulded onto their armour, all veterans were the Crux Terminatus as a symbol of their status.
  • Dissonant Serenity: Sternguard Veterans are known for being icy calm in the heat of battle.
  • Divergent Character Evolution: There was originally only a single generic "Veteran" unit that could take a variety of upgrades. Later editions split Veterans into the close combat-focused Vanguard and ranged-focused Sternguard.
  • Dynamic Entry: In previous editions, Vangaurd Veterans were one of the few units able to launch an assault on the turn that they arrived via Deep Strike.
  • Elite Mooks: Both Veteran units are upgraded versions of Tactical and Assault squads.
  • Friendly Rivalry: Due to their opposing methods of fighting. Both squads strive to outdo each other and compete for more dangerous battlefield roles. Its usually kept civil, but no matter how mean they are to each other they're still no less comrades than anyone else.
  • Jet Pack: As with Assault Marines, Vanguard Veterans often wear jump packs for greater speed and maneuverability.
  • You Shall Not Pass: One of a Sternguard Veteran's primary roles is to cover a fighting retreat by the rest of a Space Marine force, holding the enemy at bay.


We pray for our brethren who pilot the Dreadnoughts. Though they take new form, their souls, and their weapon mounts, remain pure.

The Space Marine Dreadnought is a massive war machine piloted by an honored Space Marine hero whose body has been ravaged in battle. When not needed in battle, these honored veterans are allowed to sleep in stasis.

  • Cool, but Inefficient: In gameplay, using a Dreadnought in a melee configuration the way lore depicts usually doesn't end well, special versions from other chapters notwithstanding. Even if Dreadnoughts can get into melee, at best they typically kill one or two models a round.
  • Dangerous Forbidden Technique: Well...more of a feared and revered machine, but standing above other Dreadnought variants is the Leviathan Dreadnought. Much bigger and stronger than any other Dreadnought, these were made in Terra not Mars and were designed to have force fields and tremendous amounts of firepower. However few injured Space Marines are entombed in these, as using the Leviathan Dreadnought takes a dangerously high toll on the Marine's mind and body. A Space Marine can live for centuries normally and are virtually immortal inside a standard Dreadnought, but only have a lifespan of a few years if they're encased in a Leviathan. In the most recent edition, marines encased in the new Redemptor Dreadnought undergo a similar burn-out.
  • Emergency Transformation: A Space Marine who survives crippling injuries can be interred within a life-support sarcophagus, which is connected to the Dreadnought's motive and fire control systems and allows him to pilot the machine.
  • Famed In-Story: Dreadnoughts are universally renowned within their chapter. Most players can name Bjorn The Fell-Handed, Tancred, and Davian Thule.
  • Lightning Bruiser: Dreadnoughts are surprisingly agile, able to walk and balance with the ease of a living creature.
  • Lost Technology: Because the art of constructing them has been almost lost, Dreadnoughts are revered as rare machines.
  • Man in the Machine: Marines interred in a Dreadnought continue fighting even though their original flesh bodies are broken beyond repair.
  • Old Master: Once interred within a Dreadnought's sarcophagus, the Marine inside cannot leave and is destined for a life of endless battle until destroyed. Some are so ancient their memories may extend back to the founding of their chapter and its earliest history. For this reason they are revered not just as powerful warriors but also as ageless forebears and living embodiments of battles fought long ago. Venerable Dreadnoughts are especially ancient and renowned.
  • Secret Weapon: Dreadnoughts are summoned only during times of great battle, where victory cannot be achieved through the valor of mortal men alone.
  • Siege Engines: Ironclad Dreadnoughts are designed for close quarters combat and breaching attacks, with exceptionally heavy armor and striking weapons used to smash enemy fortifications and tanks. Their projectile weaponry is also mostly designed for closer fighting than other Dreadnoughts.
  • Walking Tank: Dreadnoughts are bipedal Mini-Mecha armed with massive weapons normally seen on regular Astartes tanks, including Assault cannons, built-in Storm Bolters, flamers, plasma cannons or lascannons, as well as Power Fists and more exotic weapons for the Ironclad variant such as Seismic Hammers.
  • We Can Rebuild Him: The whole point of Dreadnoughts is to turn broken men into literal fighting machines.

The enemies of the Imperium fear many things, they fear discovery, defeat and death. But most of all they fear the wrath of the Space Marines!
