4. Chaos Space Marines
Although they share the same origin, the Chaos Space Marines are significantly stronger in Dawn of War than their loyal brothers. They come with the same powerhouse units that are heavily armored and shine in both close and ranged combat.
Unlike the Space Marines, Chaos can bridge the early game with particularly strong cultists. While they are not a significant threat themselves, they have access to grenades that the community generally considers absolutely “broken” and can wipe out entire regiments.
In addition to vehicles and Space Marines, Chaos has demons for reinforcement, and with the Chaos Lord and the Chaos Sorcerer, two extremely strong commanders. The overall playstyle focuses more on fewer but powerful units rather than a flood of “chaff.”
The tech advancement for the Chaos Space Marines is relatively fast, allowing you to access your strong units early. The biggest weakness of the faction is their susceptibility to rush tactics like those of the Necrons in certain cases.
