Blood Hunger
(Rule)Description: If a Carcharodons unit has won a combat, they must attack a sweeping advance. If for any reason the Carcharodons unit must consolidate (for example, Terminator armour), it must do so toward the nearest enemy model that they can see.
In addition, any Carcharodons Space Marine or Scout may exchange their bolter for a bolt pistol and close combat weapon for no additional cost.
