There are a lot of Warhammer 40K armies/factions. Choosing the right one is quite obviously the most critical choice you’re going to make. You’ll be spending money on the army, time building and painting it, and of course time playing with it. Choosing the wrong army for yourself could not only cost you time and money, but also your enjoyment of the game.
I will give you some tips to consider when picking an army. There’s a lot more to think about beyond how powerful a codex is. The game constantly changes, so you want something that you’ll enjoy no matter what the game throws at you.
Where to Start
There are ~28 Warhammer 40K armies to choose from. To someone looking at 40K for the first time, that can be an overwhelming amount of choices.
When I got into the game in 2006 there were around 14 Warhammer 40K armies. Still a lot, but a far more manageable amount to look through. I know if I were getting into it now and saw all the choices then I wouldn’t know where to begin. Hopefully I can guide you a bit.
How Cool Does it Look?
My biggest piece of advice to anyone looking to get into the game of 40K is to find an army you like the look of. Seriously. Unlike other smaller gaming systems out there, WH40K requires you to buy the models, assemble them, and paint them. The game has a hobby element, and if you don’t care for the aesthetics of the army then you won’t be very motivated to put them together and get it painted.
40K is not a skirmish game, so you will be putting together a lot of models and doing a lot of painting. Definitely start by looking at armies you think are visually appealing.
Once you have found some Warhammer 40K armies you like the looks of, start refining the process by looking at those that seem to fit your play style. If you’ve never played a game then that might not be so cut and dry, but I find most of us have a general preference. I always like close combat in any game I play, and will always lean towards more brutish and aggressive types.
When I was getting into 40K, my play style preference meant starting with Orks. They’re primitive brutes who love to charge headlong at the enemy with choppas (axes), held high. By looking at them, that’s a pretty easy visual cue. Orks are big and bulky, and most are carrying a close combat weapon of some sort. Most Ork vehicles look fast and fragile, a means to reach the enemy.
That’s the thing with 40K, even without knowing a lot about the game mechanics, you can still get a good gauge on an army by looking at it; like I was saying with Orks. If you were to look at Tau then you would notice that almost every model is carrying a ranged weapon, so they like to shoot. Glancing at Astra Militarum would quickly tell you that they use a lot of tanks and infantry.
Some 40K armies, like Space Marines, have a good mix of everything as they are the generalists of the game. The models give a pretty clear indication of what an army does on the field.
What’s the Best Army for 40K?
There is no best army for Warhammer 40K. Each army’s power level changes with the release of a new codex and rules editions. What was once a very weak can become the strong, and the previously strongest shuffled to the bottom.
This is yet another reason to choose an army you like the looks of, and one that suits your style. At least that way you still have one you enjoy regardless of whether it’s the best one or not.
The Warhammer 40K Armies
Here’s a quick and dirty breakdown of the various Warhammer 40K armies. It’s not conclusive and is just an overview. There are a lot of mechanics at play with all the armies, and describing each in detail would take a very long time.
Note: All Adeptus Astartes (Space Marines), have many similarities featuring power armor (3+ save), and many of the same units and weapons. Space Marines are generalists by nature, good at everything but seldom great at anything. As a general rule they have a good mix of infantry and armored support vehicles (tanks, transports, etc). Below I will focus on their unique flavor.
Adeptus Astartes: Blood Angels– They have a focus on speed with some fast tanks and Assault Marines. Death Company is a unique type of unit to Blood Angels that’s extremely good at close combat.
Adeptus Astartes: Dark Angels– Deathwing (all Terminators), and Ravenwing (fast units), set them a part from other Marines. Fluff-wise they are the mysterious chapter of Marines if you like that dark secretive element.
Adeptus Astartes: Grey Knights – These are the elite of the Space Marines. Grey Knights focus on smaller more elite units and everyone is a psyker. Generally Grey Knights are good at close combat, but they do have some shooting.
Adeptus Custodes – The most elite army of infantry you can field. Very powerful and durable.
Adeptus Mechanicus – An elite army able to shoot and handle close combat but very fragile. It is a small army with very few units to choose from. The background is these guys make all the Imperial military gear (armor, weapons, vehicles, etc).
Aeldari (Eldar) – These guys can shoot a ton and are also very fast. Aeldari (Eldar) have some great psykers to top it all off.
Astra Militarum (Imperial Guard)– The anvil of the Imperium. These guys are your modern day military equivalent. They focus on large infantry squads with a TON of tank options for support and fire power. Astra Militarum is a weak close combat army who prefers to pound the enemy with fire power at range.
Chaos Daemons – A very diverse army in terms of unit choices but generally aimed at close combat. Daemons make thorough use of psykers as well. Most units rely on their daemonic invulnerable save (5++), instead of armor. Quite capable of putting down a lot of units, though not a horde army.
Heretic Astartes: Chaos Space Marines – The evil Space Marines. Mostly generalists like their loyal counterparts but with some daemonic flavor giving them some very unique units. Chaos Space Marines are usually effective mid to short ranged.
Heretic Astartes: Death Guard – Death Guard are followers of Nurgle. They are a very resilient and tough army. With some interesting vehicles, and the ability to take a hit, they hold up very well against anything.
Heretic Astartes: Thousand Sons – All is dust! Thousand Sons are a very psyker focused army who also has a lot of ranged weaponry that’s good at cutting through armor.
Drukhari (Dark Eldar) – Lightly armored fast vehicles and poisoned weaponry are the mainstay of Drukhari (Dark Eldar). Very much a finesse army.
Genestealer Cults – The Cult is pretty new, but based on information gleamed so far, it appears to be an army that focuses on ambushing your opponent. They have access to some elements of the Astra Militarum as well.
Harlequins – Yet another new’ish army to 40K, and also another very small one. Harlequins are fast, but I have not faced them so my knowledge is lacking here; sorry. I do know they are really intended for inclusion in an Eldar or Dark Eldar army. (If anyone has a good brief overview of these guys it would be appreciated)
Inquisition – There isn’t much to these guys these days. The Inquisition is mostly a handful of models and units that are intended to play alongside other Imperial armies.
Necrons – Slow moving robotic zombies who shoot a lot. They do have some good close combat units as well, and they work on a reanimation protocol system where they just keep getting back up.
Officio Assassinorum – This army only consists of four models. The assassins are meant to be played alongside other Imperial armies. The assassins have some great unique abilities, each one focusing on one particular element.
Orks – Quantity over quality is how Orks operate. Barely armored brutes who love close combat. Orks can also do well with shooting if taken in enough quantity to compensate for their terrible ballistic skill.
Questor Imperialis – If you like big giant robots then look no further. Imperial Knights are a small group in terms of how many models you’ll use because they eat up a lot of points. Great fire power, great in close combat and fast.
Sisters of Battle– The only female army in 40K. They are like Space Marines (power armor and bolters), but physically weaker. Adepta Sororitas have some unique tanks and work using a faith system to gain bonuses. Sisters are weak in close combat and prefer to shoot.
T’au – These guys feature a lot of high powered long ranged fire power. T’au prefer to kill their enemy at range and they do it well.
Tyranids – Lots and lots of bugs to swarm the enemy with. Tyranids have a good mix of shooting and close combat, be it with hordes of bugs or utilizing large monstrous creatures. They also have a fair amount of psykers. Tyranids rely on synapse to keep themselves focused.
Ynnari – A Eldar alliance between Aeldari and Drukhari.
Nothing I’ve said here is black and white. The beauty of 40K is that you can play an army any way you like really. An army that focuses on shooting doesn’t mean it’s incapable of being built for close combat. Horde factions can be played in a more elite manner, not just swarming the enemy.
Very little is cut-and-dry, so do some research on the Warhammer 40K armies you’re interested.
Talk with 40K Players & Research
This might have been your first step, usually is, talking to other players. Most of us get into 40K because we have friends who play and talk about the game, and that’s where the interest begins. From there we start looking at armies, often armed with some knowledge. Regardless of which order you go through, the below is useful information.
Once you have a general idea of the Warhammer 40K armies you enjoy, talking with other players will help you cement your choice. The game has a lot of fine details, and an experienced player can help guide you to an army.
For example, there are a handful of Warhammer 40K armies in the game that really do well with close combat, but how each one approaches it will vary. Orks will often try to drown the enemy in numbers and swarm forward where Grey Knights can use more elite assault units and fewer models.
Some factions will favor certain tactics, like stealth and speed, where others are more direct. There is no better way to get all this information on the different armies for 40K than experienced players.
Gaming Stores & Community
If you don’t know anyone who plays 40K then most employees at gaming stores are more than happy to chat about the game and answer questions. If all else fails, hit up the internet. You can find some great communities that are friendly to new players.
I don’t really participate in forums these days but the only forum community I can safely recommend is The Bolter & Chainsword. B&C is a forum focused on Space Marines, but it does also cover all other Warhammer 40K armies and the game in general. You can also try your luck with groups on Facebook, though I find they move to fast to be of much use.
There are a lot of blogs dedicated to one particular army, or a few Warhammer 40K armies. Some of those blogs will have some great information, and some authors will be kind enough to help you out if you post a comment.
For example, I would gladly help anyone out interested in Chaos Space Marines. Greggles is a very friendly guy who I’m sure would help an aspiring Ork player out. NafNaf recommends the Dark City forum for Dark Eldar players.
With a little luck you can find some awesome blogs that might already have answers to your questions. I do also have a rather extensive list of wargaming bloggers you can check out, as well as a list of top wargaming bloggers I recommend reading.
Bear in mind that everyone has their preferences and their own personal experiences when giving advice on Warhammer 40K armies. We don’t all see each army the same way. Eldar can be seen as overpowered to one person, but someone else will say how balanced they are. Experiences and perception will impact advice given, so do not rely on a single source of information for this reason.
Choosing the right army for yourself will make a huge difference in how you perceive the game. Choosing something based on how powerful it is isn’t a good idea. Power level is in a constant state of flux. A new codex, or rules release, can move a strong army from the top to the bottom. If you start with something you like the looks of, and it fits your play style, then you will find the game far more enjoyable and rewarding. There are ebbs and flows in the game of 40K, and having an army that fits you will make riding those waves easier and less noticeable.
