Krak Grenades In close combat Tyrannic War Veterans can choose to use krak grenades as close combat weapons. Regardless of the number of attacks on a model's profile and modifiers for charging or having two weapons, each model may only make one attack with a krak grenade, hitting on a 6+ normally, or 3+ if against a Preferred Enemy. Any hits are resolved at Strength 6, ignoring Armour Saves.
