Gore-gruntas are the Ironjawz notion of cavalry: take the nastiest boar-beast in the realms, bolt armour to it, and put an orruk on top with a spear-length gore-hacka and no concept of restraint. A gore-grunta charge arrives as a single rolling crash of tusk, iron and appetite, and what it leaves of a battle line rarely reforms.
Gruntas are foul-tempered, iron-hided and permanently hungry, which is exactly why the Ironjawz adore them. Riders and mounts bond over shared priorities — running fast, hitting hard, and eating whatever stops moving — and veteran pairs learn to hunt together with an instinct that looks almost like teamwork. Almost.
