Chaos Guard

Chaos Guard is a generic term for humans at war on side of Chaos. Their exact nature is mostly defined by origin. Renegade Guards regiments would fall under either Crone Eldar or Fallen Marine overlords, most of these battle-groups act like jack-of-all-traits to compensate for the fact they will be outnumbered by loyalist forces. They have to adapt to each different battle then use their small force to defeat a larger force, Chaos Guards battle-groups that failed to master this are quickly crushed by overwhelming Imperial troops. The nature of the fighting for the Chaos Guard makes some battle-groups more elite and the Warp kills all the weaklings who failed to become tougher. What the Chaos Guard lacks in troops or weapons are more than made up for by Warpcraft and smart officers. How the Chaos Guard is often in a position of rebellion or under an overlord's service that lives inside the Warp, have them use cheaper weapons and armor. The industry and looting that supply the Chaos Guard is simply not enough to keep up with Imperial manufactorums, leading to the rise of Autoguns being used by Chaos Guardsmen instead of Las weapons along with cultist militias forming.

At worst if all of the different Chaos Guard battle-groups somehow managed to unify, they become a Segmentum level threat. Of course, this never happens as the closest thing to that is 1 or 2 sectors being threatened near the Eye of Terror and the Maelstrom by battle-groups during a Black Crusade. Given this low priority, the Imperium never totally snuff out the Chaos Guard instead fighting Orks or preventing Dark Eldar raids.

Battle-groups raised from primitive or ruined Chaos controlled human worlds are the stereotypical cultists, mutants, and madmen. Whenever Crone Eldar or Fallen need an expendable soldiers or workforce they visit such worlds and herd the fodder into transporters. Chaos controlled worlds that have actual infrastructure raise more or less like PDF battle-groups. Equipt with stubbers or some las, and iron armor. There is minor sorcery, gifts from the Gods on officers and elite subdivisions. These battle-groups are often brought along by greater forces but might do their own raiding or piracy in frontiers.

Traitor Guard that were turned fight as they did before, but with less supply and more sorcery, sometimes demons. Materials tend to deteriorate with time. Skills too if they recruit replacements from cultists. If they have a specific Chaos patron, they may move over to its doctrine in time such as Khornate charging, Nurglich chemical or bio weapons and so on. Usually, they follow the orders of whoever turn them traitor. Otherwise, will either join larger Chaos forces or establish territory somewhere the Imperium is unlikely to pursue them short term. Regiments that prevent deterioration in at least skills act like oversize mercenary outfits that take payment in arms and armor. These battle-groups use either Imperial Guard or recycled equipment along with rarely weapons better than the average Guard regiment. They try to have some internal manufacturing capability if possible and recruit from cultists or slaves but retain the same standards and training before defection. Raiding for supply or assist other Chaos forces for pay is also common.
