Accept any Challenge, no Matter the Odds

Any unit that can declare a charge (i.e has not fired Rapid Fire or Heavy Weapons) must do so if they are in range of an enemy unit at the start of their Assault phase. In close combat, Black Templars units count as having the Preferred Enemy special rule against the enemy army. Neophytes do not benefit from this vow. If there are only Neophytes left in the unit, they are no longer bound by this vow. Dreadnoughts in the army are bound by this vow.
