If a unit includes at least three models with the Iron Bulwark special rule and is not locked in combat, all friendly models in that unit (including those without the Iron Bulwark special rule) gain the Battle-hardened (1) special rule for the duration of any Assault phase in which the unit is successfully Charged by one or more enemy units.
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.
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.
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.
