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.
A model with this special rule may issue and accept Challenges as if it had the Character type. Note that this does not allow a model with this special rule to use any other special rules associated with the Character type.
When a model with this special rule suffers an unsaved Wound, it can make a special Feel No Pain roll to avoid being Wounded (this is a special Saving Throw which is made after unsaved Wounds are suffered). Feel No Pain rolls may not be taken against unsaved Wounds that have the Instant Death special rule. Roll a D6 each time an unsaved Wound is suffered. On a result that is equal to or greater than the value in brackets, the unsaved Wound is discounted - treat it as having been saved. On any other result the Wound is taken as normal. For example, a unit with the special rule Feel No Pain (5+) would need to score a 5 or 6 in order to discount a Wound inflicted upon it. This is a Damage Mitigation roll - any model may make only a single Damage Mitigation roll of any type for any given Wound (see page 174).
True Believers:A model with this special rule may never have a Leadership Characteristic modified below a value of 6. Futhermore if one or more models with this special rule are part of a combat that results in a draw, then the side that includes one or more models at the end of the fight sub-phase with this special rule is counted as having won the combat by 1 point. If both sides include models with this special rule then the combat remains a draw.
In a turn in which a model with this special rule Charges into combat, it gains a number of Attacks equal to the value of X for Charging, rather than +1. A model that has made a Disordered Charge that turn receives no benefit from Rage (see page 182).
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.
