Models with the Bulky (X) Special Rule take up more space on Transport Models."
A Model with the Bulky (X) Special Rule does not use up 1 Point of Transport Capacity when it Embarks on a Model with the Transport Sub-Type. Instead it uses up a number of points of Transport Capacity equal to the value of X attached to eh variant of the Bulky (X) possessed by that Model.

"A Unit that includes Models with this Special Rule scores fewer Victory Points for controlling Objectives, but can score Victory Points destroying enemy Units that hold Objectives."
A Unit that includes a majority of Models with the Vanguard (X) Special Rule may only ever score 1 Victory Point for Controlling an Objective, regardless of that Objective's value (see Core Missions in the Warhammer: The Horus Heresy - Age of Darkness Rulebook). However, the Player that controls a Unit that includes a majority of Models with the Vanguard (X) Special Rule gains Victory Points equal to the value of the X in the Vanguard (X) Special Rule, in addition to any Victory Points scored for controlling an Objective, whenever either of the following two statuses are fulfilled:

- If an attack made for a Unit that includes a majority of Models with the Vanguard (X) Special Rule causes the last Model in an enemy Unit that is Controlling or Contesting an Objective to be Removed as a Casualty.

- If a Unit that includes a majority of Models with the Vanguard (X) Special Rule has at least one attack made for it in a Combat that results in one or more enemy Units that had at least one Model within 3"" of an Objective at the start of that Assault Phase either Falling Back from Combat or being Massacred.

Note that the Vanguard (X) Special Rule may only be used to score Victory Points once per Objective per Player Turn - no matter how many enemy Units were Controlling or Locked in Combat near that Objective.

"Models near an enemy Model with the Fear (X) Special Rule must reduce their Advanced Characteristics."
When any Model from a Unit is within 12" of an enemy Model with the Fear (X) Special Rule, all Models in that Unit must reduce their Leadership, Willpower, Cool, and Intelligence Characteristics by the value of X. This negative modifier is removed as soon as no Models in a given Unit are within 12" of any Model with the Fear (X) Special Rule. If a Unit would be affected by multiple instances of the Fear (X) Special Rule, the value of X is not stacked and instead the single highest value is used as a negative modifier.

"Models with this Special Rule can make Volley Attacks with other Weapons."
The Controlling Player of a Model with this Special Rule treats all Ranged Weapons such a Model has that do not have any variant of the Heavy (X) Special Rule or Ordnance (X) Special Rule as having the Assault Trait.

"Feel No Pain (X) is a Damage Mitigation Test that may be taken in addition to a Saving Throw."
A Model with the Feel No Pain (X) Special Rule gains a Feel No Pain Damage Mitigation Test that may be used in Step 9 of the Shooting Attack process or Step 8 of the Initiative Step of the Fight Sub-Phase process to discard wounds allocated to the Model. A Damage Mitigation Test may be made after and in addition to a Saving Throw. The Target Number for a Feel No Pain Damage Mitigation Test is the value of X attached to the specific variant of the Special Rule.
