A unit containing one or more Fear-causing models gains +1 to its Combat Resolution score. If the Unit Strength of all Fear-causing models is double or more that of the total Unit Strength of all enemy units in base contact, the Combat Resolution score is increased by +2. Note that the bonus from Fear is otherwise not cumulative for having multiple units with the Fear special rule involved in the same combat.

If the majority of the models in a unit cause Fear, they also gain the Immunity (Fear) special rule (described later), and thus the Combat Resolution bonus of their Fear-causing enemies is ignored for that unit.
