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.
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 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.
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.
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.
Lords of Profligacy After a Shooting Attack has been resolved against a unit composed entirely of models with this special rule, if that unit is not Falling Back, its controlling player can choose for it to become Stupefied. If a unit becomes Stupefied while Pinned or affected by the Blind or Concussive (X) special rules, it ignores the effects of these while Stupefied. Stupefied A unit that is Stupefied can only fire Snap Shots and cannot make Reactions in any Phase. If a unit that is Stupefied has a Charge declared for it, then that Charge is always considered to be Disordered. Furthermore, whilst Stupefied, all models in that unit increase their Strength Characteristic by +1 and when a model in a Stupefied unit suffers an unsaved Wound, it can make a special Stupefied roll to ignore it. Stupefied rolls may not be taken against attacks that have the Instant Death special rule. Roll a D6 each time an unsaved Wound is suffered. On a 6+, the unsaved Wound is ignored. On any other result the Wound is applied as normal. Add 1 to Stupefied rolls made for units which have the Fearless special rule. A Stupefied roll is a Damage Mitigation roll – any model may make only a single Damage Mitigation roll of any type for any given Wound. At the end of its controlling player’s following turn, the unit is no longer Stupefied. Whilst it is Stupefied, a unit does not take further Morale checks in the Movement phase or Shooting phase and cannot be Pinned. If the unit is forced to move, for example, if it has to Fall Back, it is no longer Stupefied. If assaulted, the unit will fight as usual, but enemy units do not receive the Initiative penalty for having Charged a unit through Difficult Terrain, even if the Stupefied unit is in Difficult Terrain. If a unit becomes Stupefied while making a Charge, then that Charge continues as normal, but is automatically counted as Disordered. Units that are locked in combat can be Stupefied, but take Morale checks in the Assault phase as normal and if forced to Fall Back are no longer Stupefied.
