Squig Herds are composed of both Night Goblins and Squigs. So long as the unit includes both types, shooting attacks upon the unit are randomised as follows. 1-4 hits a Squig, 5-6 hits a Night Goblin. In close combat enemy models must attack the type of models they are in base contact with (or can choose if in base contact with both Squigs and Night Goblins). All casualties are taken by removing models of the appropriate type. Bring models forward from the rear ranks to fill any gaps that result.
