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.
Bulky models count as a number of models equal to the value X in brackets after the rule’s name for the purposes of Transport Capacity and whether a given unit outnumbers another in combat. For example, a unit comprised of five models all of which have the Bulky (3) special rule, would count as 15 models when attempting to Embark on a Transport Vehicle or when deciding if they outnumber an enemy unit.
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.
When a model with this special rule suffers an unsaved Wound, Glancing Hit or Penetrating Hit, it can make a special Shrouded roll to ignore it (this is not a Saving Throw and so can be used against attacks that state that 'no Saves of any kind are allowed'). Shrouded rolls may not be taken against Melee Attacks, against attacks with the Ignores Cover special rule or for models with the Fearless special rule. Roll a D6 each time an unsaved Wound, Glancing Hit or Penetrating Hit is suffered by a model with this special rule. On a result that is equal to or greater than the value in brackets, that unsaved Wound, Glancing Hit or Penetrating Hit is ignored. On any other result, the Wound, Glancing Hit or Penetrating Hit is applied as normal. For example, a unit with the special rule Shrouded (6+) would need to score a 6 in order to ignore a Wound, Glancing Hit or Penetrating Hit inflicted upon it. If on any unit this rule is presented simply as Shrouded, without a value in brackets, then count it as Shrouded (6+) This is a Damage Mitigation roll - any model may make only a single Damage Mitigation roll of any type for any given Wound, Glancing Hit or Penetrating Hit (see page 174).
When a unit that contains at least one model with this special rule takes Morale checks or Pinning tests, the unit ignore any negative Leadership modifiers. If a unit is both Fearless and Stubborn, the unit uses the rules for Fearless instead.
When an enemy unit successfully Charges a unit that includes one or more models with this special rule, the Charge is always considered to be Disordered.
