How to Paint Everything: The Astra Militarum

In our How to Paint Everything series, we take a look at different armies of the Warhammer universe, examine their history and heraldry, and look at several different methods for painting them. In this article, we’re looking at how to paint the brave warriors of the Astra Militarum.

Who Are The Astra Militarum?

Commonly known as the Imperial Guard, the Astra Militarum are the Imperium’s standing army of regular old humans. Making up the vast majority of the Imperium’s military forces, Guard soldiers are the first line of defense against the threats to the Imperium. Every world in the Imperium has its own force of guard, and soldiers in the Guard are drawn from worlds across the galaxy and stationed in locations of strategic or cultural importance. On the ground, the Astra Militarum’s infantry forces are supported by legions of heavy tanks and artillery and in the air, they’re supported by the Imperial Navy. While the Adeptus Astartes are the Emperor’s Angels of Death, making surgical strikes and taking out key targets, the Guard are the Emperor’s Hammer, acting as the full armored might of the Imperium. The Astra Militarum’s origins date back to the Emperor’s Great Crusade, when the fledgling Imperium needed a way to supplement the work of the legions of Space Marines reclaiming the galaxy. As the Space Marines spread across the galaxy, the Imperial Army was formed to supplement them, recruiting brave men and women from countless worlds in the growing Imperium. These human forces acted as expeditionary forces, eventually acting as the forefront of the Great Crusade, fighting alongside (and under) the marine legions. In the wake of the Horus Heresy, these ties were cut, and the Imperial Army became the Astra Militarum, split into two branches: The Imperial Guard and the Imperial Navy. The new organizational structure was designed to reduce the power of any individual commander or regiment, and ensure that, should a regiment turn against the Imperium, their treachery would be limited to a small area of influence.

The Imperium is massive, and its core strength comes from its people. There is rarely, if ever, an Imperial conflict that doesn’t involve the Astra Militarum and its forces. As such, they’ve been involved in every major conflict in the Imperium’s history, from the Horus Heresy and the battle for Terra, where Solar Auxiliaries helped defend the Emperor’s Palace, to the Fall of Cadia and the ensuing Indomitus Crusade. The guard are made of a great many regiments whose deeds are legendary, from the Steel Legions of Armageddon to the indomitable forces of Cadia, who held even after the planet itself was destroyed.

Where to Read More

The Imperial Guard feature in a ton of 40k literature, and there are a lot of really great stories about them. So we’re gonna talk about our favorites here.

  • The Gaunt’s Ghosts series by Dan Abnett is a massive collection of 16 novels that document the struggles of the Tanith First light inantry regiment of the Imperial Guard during the Sabbat Worlds Crusade. They’re led by the legendary Ibram Gaunt and span the entire history of Games Workshop’s Black Library, with novels published as early as 1999 and as late as 2019. It’s a big investment, but many of the Ghosts books are regarded as some of the best in the Black Library works.
  • Honourbound by Rachel Harrison is a relatively recent novel that covers the exploits of Severina Raine, an Imperial Guard commissar of the 11th Antari Rifles. Goonhammer’s Coda wrote a glowing review of this one already, if you’re looking for motivation.
  • The Ciaphas Cain series is a collection of books chronicling the life and deeds of Commissar Ciaphas Cain, with the stories presented as taken from Cain’s personal notes and collected following his death. Cain’s an unreliable narrator, and extremely self-centered, though Cain himself never becomes someone you hate. There are ten books in the series, plus a number of short stories if you’re looking for more.
  • Helsreach by Aaron Dembski-Bowden is about the defense of the Helsreach Hive during the 3rd War for Armageddon and while it’s written from the perspective of Black Templars Chaplain Grimaldus, it features the guard throughout, including Andrej Valatok, a Steel Legion Storm trooper with the biggest balls in the galaxy.

Other book recommendations from the Goonhammer crew: 15 Hours (which our friends at the 40k Badcast read way back when), Shadowsword, and Baneblade all got thumbs up when I asked for people to list their favorites.


Covered in This Article:

  • Methods for painting the various units of the Astra Militarum, from basic guardsmen to elite infantry to tanks.
  • How to paint notable regiments of the Astra Militarum, such as Tempestus Scions, Kasrkin, and Death Korps.
  • How to paint notable elements of the Astra Militarum, such as power weapons, heraldry, and heat scarring.

Common Visual Elements of the Astra Militarum

The regiments of the Astra Militarum offer near endless variety for 40k players – there are countless Imperial worlds in the galaxy, each contributing its own regiments with their own color schemes, formations, and combat tactics. Any discussion of painting Astra Militarum has to focus on the army’s two key facets: Painting dozens of infantry, and painting tanks. In this section, we’ll address both how to paint the infantry, both from the standpoint of how to create good schemes that unify your army and look great on the tabletop, and also from the standpoint of how to avoid losing your mind as you paint 60 to 120 guardsmen. The soldiers of the Astra Militarum come from a wide variety of backgrounds and environments. They come in all shapes and sizes, and all colors, genders, and walks of life. Painting them requires painting skin regularly, something that we covered in great detail in our How to Paint Everything: Human Skin article. We recommend you read and refer to that that as a companion piece to this article.

Power Weapons

We’ve covered power weapons in this articlewhich covers everything from power swords and axes to crazier weapons.

Weathering

If you’re painting tanks which have been through hell and back, you’re going to want to do some weathering. You can find our guide to painting weathering here.

That wraps up our look at the regiments of the Astra Militarum, but there are plenty more schemes that we haven’t covered – the sky’s the limit when it comes to this army and there’s a ton of room for conversions and other schemes you can paint.
