Solar Auxilia

Of the myriad regiments and battalions of the Excertus Imperialis, more commonly referred to as the Imperial Army, the Solar Auxilia were among the most elite, disciplined and well-equipped fighting forces of the burgeoning Imperium of Man during the Great Crusade and Horus Heresy eras in the late 30th and early 31st Millennia. They were widely considered by many second only to the superhuman Legiones Astartes in their military effectiveness in battle. While some observers may point to singular units and individual regiments whose skill, power and reputation may arguably exceed that of the Solar Auxilia, such as the legendary Lucifer Blacks or the gene-wrought Marnean Armsmen, what marks the Solar Auxilia apart is the fact that they are not simply a single regiment raised from a particular culture or displaced from a warlike Compliant world to serve the Imperium.
