Goblin Wolf Riders

Goblin Wolf Riders scour the flanks of every Waaagh! and the breadth of the Badlands besides, mounted on giant wolves as lean and vicious as their riders. They are raiders before they are soldiers: burning outlying farms, running down messengers, looting supply trains, and vanishing over the horizon before anyone organized enough to matter has finished buckling on a sword-belt.

In open battle they circle like flies, loosing arrows and jabbing spears wherever a line shows its back, then fleeing (expertly, shamelessly) the moment it does not. Warbosses call them cowards, which is true, and indispensable, which is truer. No greenskin horde has ever starved or stumbled into ambush while its wolf riders were kept paid in loot and leftovers.
