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 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.
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.
If a model with this special rule ends its Charge Move in base or hull contact with an enemy model, it makes a number of additional attacks equal to the value in brackets listed as part of this special rule.These attacks hit automatically and are resolved at the models unmodified Strength with AP-. These attacks do not benefit from any of the model's special rules (such as Furious Charge, Rending, etc.).These attacks are resolved during the Fight sub-phase at Initiative step 10 but do not grant the model an additional Pile-in Move. If a model with this special rule Charges a Vehicle of any kind or a Building, the hits are resolved against the Armour Value of the Facing the charging model is touching. If the model is in contact with two or more Facings, the player controlling the target model chooses a Facing upon which the attacks are resolved. If a model with this special rule Charges a Building or Vehicle that is a Transport, the hits are resolved against the Building or Vehicle, not the unit Embarked within the Building or Vehicle.
Wrack & Ruin: When a model with this special rule makes a Shooting Attack or Melee attack targeting a model with the Dreadnought, Automata, Vehicle or Building Unit Type it gains +1 to the Strength of that attack.
