Warhammer 40,000 Dark Millennium features a class system. As of yet we only have one confirmed faction and one confirmed class.
The class system features classes that share a parallel in the opposite faction. It has been said that though the two faction of Order and Destruction have parallel roles a race may not necessarily have the same set of classes as another race. For example, a class such as the Black Templar Space Marine of the Imperium of Man race will class not necessarily have a counter part in the Eldar race even if the two are both members of Order faction. The Imperial Class however will have a counterpart in the destruction faction.
