Dark Pikemen
Pikemen appeared a long time ago, when dwarves lived in the most remote corners of the dungeons and were no different from their light counterparts. Dwarves understand that the enemy cannot be allowed to get close and try in every way to prevent them with their pikes, and outcasts rarely gather in groups, and it is especially important for them to avoid losses.

Dark Guards
The dwarven guards caused Laslo's red troops a lot of trouble; the defensive formations looked like hedgehogs of spears, and the renegades simply could not get close to them - they ran into the spears and died without even engaging in combat.

Bruisers
When the dwarves emerged from the tunnels, they encountered orcs, and if their soldiers ran into spears, things were tougher with the Warmongers. In response, the dwarves put forward new troops trained to stun and maim orcs.

A huge thank you to psatkha for the advice and to Death Knight for the support.
