Solar Auxilia were elite human units of the Imperium during the Great Crusade and Horus Heresy. They belonged to the most disciplined and best-equipped forces of the Excertus Imperialis – the Emperor’s army. Their training, equipment, and tactics ranked them just behind the Legiones Astartes.

Solar Auxilia operated in extreme environments – from toxic worlds to vacuum. They used void armor, lasrifles, volkite, and heavy machinery such as Dracosan or Malcador. Their strength lay in precise tactics, massive firepower, and unwavering loyalty.

In the Horus Heresy game system, they have access to units such as Lasrifle Sections, Veletari Storm Sections, Aethon Heavy Sentinels, and Tactical Command. They are ideal for players who want to field a numerous but elite human army with a rich history and tactical depth.
