Warhammer 40k features three main factions (each with their own races): Xenos aliens, the Chaos Gods, and, of course, the mighty Imperium of Man! Warhammer 40k features dozens of different factions, all with unique play styles, lore, lists (how you build armies), and miniatures! However, with so many to choose from, it can sometimes be overwhelming to pick your favorite. Even if you already have a bunch of miniatures, sometimes you want to know a little more about the lore and background before starting to collect a new army.

Picking a Warhammer 40k faction (army) is all about what makes you excited to roll dice and tell stories. Here’s what to keep in mind:

  • Playstyle: Love smashing things in close combat? Or raining lasers from a distance? Every faction plays differently, so think about what you’ll enjoy most.
  • Lore and Theme: Into noble heroes, ancient aliens, or chaos-worshipping maniacs? Warhammer 40k has it all. Find the faction that makes you go, “That’s my squad!”
  • Models and Looks: You’ll be spending hours painting these bad boys, so pick an aesthetic you love—whether it’s the brutal Orks, sleek Eldar, or grim Space Marines.
  • Customization: Want to tinker and kitbash your army into something totally unique? Chaos and Orks are a hobbyist’s dream, while others like Tau are more streamlined.

At the end of the day, the best faction is the one you’ll enjoy building, painting, and playing. With over 20 factions in the latest edition, there’s no wrong answer—just pick what makes you smile (or cackle).

Playstyles & Tactical Strengths of Warhammer 40k Armies

World Eaters:

The World Eaters are the embodiment of rage-fueled brutality. Led by the infamous Angron, these Chaos-worshipping Space Marines charge into battle with one purpose: to drown the galaxy in blood for their god, Khorne. If you’re the kind of player who enjoys overwhelming your opponent with sheer force, the World Eaters are the Warhammer 40k army for you. These maniacs excel in close combat, where their infamous Berserkers tear through enemy lines, leaving little but gore in their wake. Their strategy? Charge headlong into the thick of it. Tactics? Who needs them when you have chainaxes and the blessings of the Blood God?

Orks hor wal how to play codex warhammer 40k guideOrks:

For the Orks, it’s simple—if it moves, it’s worth smashing. And if it doesn’t move, smash it anyway! Orks live for the thrill of battle, and their armies reflect this chaos; there’s a reason they are a favorite race in Warhammer 40k. Each Ork warband is a rough-and-tumble crew of green-skinned hooligans ready to overwhelm the battlefield with sheer numbers.

Their WAAAGH! energy lets them sprint across the battlefield, closing the distance for brutal melees. Think of them as the ultimate bar fight—just on a galactic scale. Armed with crude yet deadly choppas, they specialize in swarming the enemy with reckless abandon. The best part? Every time you charge in, it’s a laugh riot, both for the Orks and the players, also making them one of the most fun Warhammer 40k armies.

new blood angels models releasesBlood Angels:

On the surface, Blood Angels may seem like refined warriors, but underneath their noble appearance lies the ever-looming Red Thirst. These noble sons of Sanguinius are a top choice if you love the drama of battle as much as the thrill of close-quarters combat. With jetpacks and gleaming weapons, Blood Angels use speed to their advantage, crashing into enemy armies with furious elegance in Warhammer 40k.

The Black Rage pushes their warriors into a berserker frenzy, making their Death Company some of the most fearsome melee fighters in the Warhammer 40k universe. Whether they’re soaring into the fray or succumbing to madness, they bring the fight up close and personal.

Ranged-Dominant Armies

meta tau crisis warhammer 40k hor walTau Empire:

If you prefer precision over brute force, the T’au Empire might just be your perfect fit. Known for their advanced technology, the T’au armies take a much more calculated approach to war in Warhammer 40k. Rather than rushing into battle, these guys prefer to stand back and obliterate foes from a distance.

Their battlesuits and high-powered railguns are the stuff of nightmares for any opponent caught on the wrong end. With drones and long-range firepower, the T’au’s strategy revolves around mobility and coordinated strikes. They believe in the “Greater Good,” but make no mistake—when their pulse rifles start firing, it’s nothing but bad news for their enemies.

astra militarum battleforce Warhammer 40k armiesAstra Militarum:

The Astra Militarum, or the Imperial Guard, are the backbone of the Imperium, and their massive armies in Warhammer 40k reflect that. These are ordinary humans with extraordinary numbers. What they lack in flashy powers, they make up for in sheer firepower. Guard armies rain death upon their enemies from afar, using artillery, tanks, and an endless supply of lasguns. Their long-range weapons and heavy armor make them an incredibly resilient force when positioned correctly. The trick to success with the Guard? Keep your distance, overwhelm with firepower, and make sure those tanks keep rolling.

Necrons 40k detachment rules 4 Warhammer 40k armiesNecrons:

The Necrons, the ancient robotic overlords of the galaxy, take a cold, calculated approach to war. Their mastery of Gauss weapons and devastating particle beams allows them to shred through enemies from across the battlefield. Necron players love to keep the opponent at arm’s length, all while systematically dismantling them.

But the Necrons aren’t just about firepower—they also possess a relentless ability to reanimate. So, while you’re dishing out death at range, your forces are steadily coming back to life, making Necrons one of the most resilient factions and armies in Warhammer 40k. If you’re the type who enjoys winning wars with tactics, firepower, and inevitability, Necrons are your guys.

Psychic-Dominant Warhammer Armies

Grey Knights Combat Patrol Warhammer 40k armiesGrey Knights:

For those who enjoy mixing magic with mayhem, the Grey Knights are a perfect army choice in Warhammer 40k. These elite warriors are all psykers, each wielding devastating psychic powers alongside their formidable weapons. Whether they’re banishing daemons back to the warp or slicing through foes with their nemesis force swords, Grey Knights dominate the battlefield with a mix of psychic might and physical prowess.

They might not have as many units as other factions, but each one packs enough power to hold the line or lead a decisive strike. If subtlety isn’t your thing, wield the warp and cut down enemies with the best psychic warriors in the Imperium.

Thousand sons Combat Patrol Warhammer 40k armiesThousand Sons:

On the flip side of psychic mastery, the Thousand Sons bring a more sinister edge to their spell-slinging. Once loyal to the Emperor, this Chaos Space Marine faction has embraced the power of Tzeentch, the god of change. Thousand Sons are psychic powerhouses, capable of casting devastating spells that bend the battlefield to their will. Their warriors, encased in arcane armor, wield sorcery to annihilate enemies from afar or summon daemonic reinforcements. If you like playing mind games—literally—these sorcerers will keep your opponents guessing while your psychic storms tear them apart.

psychic awakening aeldari 5Craftworld Aeldari:

The Aeldari (or Eldar, if you’re feeling old-school) are a dying race in Warhammer 40k, but they haven’t lost their mastery over the psychic arts, and their armies are some of the most elite out there. Craftworld Aeldari armies are built around their unparalleled psychic abilities, allowing them to manipulate the battlefield and turn the tide of battle with a thought. Farseers and Warlocks lead their forces, weaving complex webs of psychic power to guide their troops or devastate their enemies.

Their psychic prowess is complemented by their highly specialized units and sleek, mobile warfare. If you’re a player who loves a strategic, hit-and-run style mixed with powerful magic, the Aeldari will keep you on your toes.

Warhammer Commemorative Series Leagues of Votann The Ancestors WrathWhen picking your first Warhammer 40k army, it’s important to consider your playstyle, aesthetics, and how easy or hard it is to collect and play that faction. Here’s a breakdown of what you should think about:

  • Playstyle: Are you the kind of player who likes to charge headfirst into the fray? Or maybe you prefer to sit back and rain firepower from a safe distance? Consider how each faction fights: some are all about close combat, others excel at ranged warfare, and some rely on psychic powers or tricks to win.
  • Aesthetics: Let’s face it, you’re going to spend hours building, painting, and admiring these models. So, you should absolutely pick a faction whose look speaks to you. Do you want the noble armor of the Space Marines, the menacing robotic legions of the Necrons, or the sleek, high-tech style of the T’au Empire? Whatever army you pick, you’ll be spending a lot of time with it, so make sure you love how it looks.
  • Ease of Use: Some armies are more beginner-friendly than others.

What is the Strongest Faction (& Army List) in Warhammer 40k?

Knight Commander Pask Lore Warhammer 40k Leman Russ 2The power rankings of Warhammer 40k factions, army lists, and races are like a rolling tide—constantly shifting with each edition, balance tweak, and player approach. While certain factions might seem to hold an edge in specific areas, there’s no ultimate “best” army list or faction that dominates all. Games Workshop keeps the game fresh with regular updates, including Dataslates, FAQs, and point adjustments, meaning the top dogs today might just be underdogs tomorrow.

Debates over faction strengths and weaknesses are a staple of the community, and perceptions often swing as new rules hit the table. But it’s not just about the rules—army composition, tactical choices, and player skills all play a massive role in shaping the outcome of any given skirmish.

At its core, Warhammer 40k is built to give players a fair shot at fun and competitive matches no matter which faction, list, or race they roll with. The game thrives on variety, keeping every army relevant and the battles unpredictable

Warhammer 40k Factions: The Imperium of Man

Free Emperor vs Horus Artwork DownloadThe Imperium of Man looms large in the Warhammer 40k universe—a sprawling, galaxy-spanning juggernaut packed with more list-building options than you can shake a chainsword at. This iron-fisted empire was forged in the aftermath of the Horus Heresy, a civil war so catastrophic it nearly wiped out humanity. At its helm sits the God-Emperor, a near-dead deity entombed on the Golden Throne, keeping things running through sheer divine willpower (and probably a lot of duct tape).

Life in the Imperium? Not exactly a picnic. Every citizen is just another gear in the endless war machine. The hierarchy is oppressive, the dogma is suffocating, and stepping out of line usually ends with a fiery “heresy” stamp on your forehead. Want the lowdown on the Imperium’s many factions? Check out our guide—it’s got everything you need to know.

Despite its size and strength, the Imperium is constantly teetering on the edge of total collapse, under siege from enemies inside and out. Yet, amidst the chaos, there are still those who cling to hope, driven by faith, sacrifice, and a stubborn belief that humanity’s empire can endure. Scroll on to see what makes each Imperial faction tick and how they bring their own flavor to the battlefield

Blood Angels

Blood Angels Detachment Rules blood angels wal factions focus Warhammer 40k armies

Summary

The Blood Angels are a noble but tragically cursed Chapter of Space Marines descended from the legendary Primarch Sanguinius. While they aim to live up to his ideals of grace and heroism, they’re plagued by two nasty afflictions: the Red Thirst, an uncontrollable craving for blood, and the Black Rage, a berserker madness that hits like a freight train of trauma.

Skill Level Needed to Play Blood Angels

Intermediate: Charging headfirst into battle might sound easy, but there’s an art to knowing who to send in first, when to hold back, and how to rack up points while keeping things together. That said, they’re a blast to play, especially in casual games—sometimes running straight at the enemy is all the strategy you need.

Review

Warhammer 40k factions 3The Blood Angels are equal parts glory and tragedy, a Chapter known for their noble ideals and dark curse. Hailing from the line of Sanguinius—a Primarch so legendary he might as well have “angelic perfection” on his résumé—they carry his legacy with pride, from their martial prowess to their winged heraldry.

But there’s trouble in paradise. Beneath their shiny exterior lurks the Flaw: the Red Thirst, an unquenchable bloodlust that flirts with madness, and the Black Rage, a horrifying condition where they relive their Primarch’s final moments against Horus and lose it entirely. It’s a tough gig, but they wear their torment with pride, charging into battle as heroes, even when their curse is just waiting to take over.

Astra Militarum

Astra Militarum Vostroyan Warhammer 40k armies

Summary

The Astra Militarum, or Imperial Guard if you’re feeling old-school, is the Imperium’s go-to army of regular folks doing extraordinary things. Pulled from countless planets, these regiments of everyday men and women band together to fend off enemies that could vaporize them with a glance. Each regiment comes with its own quirks, traditions, and fighting styles, showcasing humanity’s knack for hanging tough under impossible odds.

Skill Level Needed to Play Astra Militarum

Novice to Intermediate: Sure, plopping a swarm of models on the table sounds easy, but keeping them alive? Not so much. Your troops are squishy, and if your artillery gets caught off guard, the game can go south fast. On the plus side, with sheer numbers, you’ve got room for a few mistakes without it being lights out.

Review

Each regiment has its own flavor. Whether it’s the disciplined Cadians, the rugged Catachan jungle fighters, or the steel-clad warriors of Armageddon, they bring a variety of styles and strategies to the table.

Imperial Agents

Imperial Agents Battleforce Ordo Hereticus

Summary

The Imperial Agents are the Imperium’s secret weapons—covert operatives who step in when regular armies can’t cut it. These include the Inquisition, Adeptus Arbites, Officio Assassinorum, and other shadowy organizations. Led by the no-nonsense Inquisitors, these agents have the authority to investigate, eliminate, or outright vaporize threats, even if those threats come from inside the Imperium itself. Think of them as the Emperor’s mix of detectives, judges, and assassins.

Skill Level Needed to Play Imperial Agents

Advanced: Tossing a few Imperial Agents into your main army? Easy. Running a whole army of these quirky units? That’s another story. Their odd mix of troops makes coordination tricky. If you’re new, stick to sprinkling a few agents into your existing force for flavor and impact.

Review

imeperial agents clip artThe Imperial Agents are the Imperium’s unsung heroes—or nightmares, depending on which side you’re on. These operatives act outside the usual military chain of command, tackling heretics, mutants, Xenos, and even the occasional corrupt Imperial bigwig.

Dark Angels

Warhammer 40k armies

Summary

The Dark Angels are Space Marines shrouded in mystery, obsessed with one thing: redeeming their Chapter from the stain of the Fallen, a group of traitors who broke away during the Horus Heresy. They guard their secrets so closely, they’d rather silence allies than let the truth out.

Skill Level Needed to Play Dark Angels

Novice to Intermediate: A standard Dark Angels army is straightforward, but diving into their specialized forces—like the bike-heavy Ravenwing or the elite Deathwing—adds complexity. Each plays differently, so balancing them can take some skill.

Review

warhammer 40k factions 6The Dark Angels are one of the original Space Marine Chapters, but their shining history has a dark twist.

These elite warriors specialize in covert operations, forming Kill-Teams that hunt down alien leaders, gather intel, and disrupt enemy plans with ruthless efficiency.

Skill Level Needed to Play Deathwatch

Intermediate: Since Deathwatch is now part of the Imperial Agents roster, running them solo isn’t an option anymore. Adding them to an army? Easy enough. Building a cohesive force with them? That’s where things get tricky. However, GW has promised they will be getting their own rules again at some point.
