Swift of Action: All models with this special rule add +1 to their Movement Characteristic and whenever called upon to make a roll to determine which player will take the First Turn or to Seize the Initiative, the controlling player of an army whose Primary Detachment has this special rule may roll an additional dice and discard the lowest rolled dice before determining the result.
A unit made up entirely of models with this special rule may perform a Deep Strike Assault as described on page 310. Certain Faction or unit special rules may present other options for the deployment of units with the Deep Strike special rule.
Relentless models can shoot with Heavy or Ordnance weapons, counting as Stationary, even if they moved in the previous Movement phase. They are also allowed to Charge in the same turn they fire Heavy, Ordnance, or Rapid Fire weapons.
When making a Shooting Attack, a model with this special rule may attack with a number of different weapons equal to the value of this special rule. This rule does not allow a single weapon to be attacked with more than once, and only applies if the model is equipped with more than one weapon. For example, as part of a single Shooting Attack, a model with the Firing Protocols (2) special rule may attack with up to two different weapons.
A unit that includes any models with this special rule may not join or be joined by any model that does not also have this special rule (this includes Legion Techmarines and Legion Apothecaries, which may not be assigned to a unit that includes any models with this special rule). In addition, a unit that includes any models with this special rule never counts as a Scoring unit or a Denial unit regardless of any other special rules or Mission rules in use – however, a model with this special rule may re-roll all failed Shrouded Damage Mitigation rolls.
A unit made up entirely of models with this special rule may perform a Flanking Assault as described on page 311. Certain Faction or unit special rules may present other options for the deployment of units with the Outflank special unit.
A unit that contains at least one model with this special rule that is locked in combat can choose to leave close combat at the end of any Assault phase. If the unit wishes to do so, it must take an Initiative test. If the Test is failed, nothing happens and the models remain locked in the fight. If the Test is passed, choose a direction – then roll 2D6 and add the unit’s Movement Characteristic to the result. As long as the distance rolled, in inches, is sufficient to allow the entire unit to move over 1" away from all of the enemy units they are locked in combat with, the unit breaks away from combat and must immediately move a number of inches in the chosen direction equal to the 2D6 + Movement result, ignoring the models they were locked in combat with. No Sweeping Advance rolls are made. Enemy units that are no longer locked in combat immediately Consolidate a number of inches equal to their Initiative. A Hit & Run Move is not slowed by Difficult Terrain, but does trigger Dangerous Terrain tests as normal. It may not be used to move into base or hull contact with enemy units, and models instead stop 1" away. If there are units with this rule on both sides who wish to disengage, roll off to determine who goes first and then alternate disengaging them. If the last of these ends up no longer in combat, it Consolidates instead.
