Pistol "A Model may attack with two Weapons that have the Pistol Special Rule"
During Step 3 of any Shooting Attack, a Player may choose to have a Model under their control make attacks with two Weapons rather than one if both Weapons have the Pistol Special Rule.
Rending (X) "With a Weapon that has the Rending (X) Special Rule, there is a chance that a Hit Test may result in an automatic wound."
When any Hit Test is made for an attack with the Rending (X) Special Rule, if the result of the Dice roll, before any modifiers are applied, is equal to or greater than the value of X attached to this variant of the Rending (X) Special Rule, then if a Hit is inflicted by that Hit Test, that Hit becomes a 'Rending Hit'.
When required to make a Wound Test for a Rending Hit, no Dice are rolled and the Wound Test succeeds automatically regardless of the Weapon's Strength or the Target's Toughness Characteristic. The Wound Test is treated as if the result had been '6' for the purposes of any Rules that would be triggered on certain results of a Wound Test. Wounds caused by a Rending Hit use the AP and Damage Characteristic of the Weapon used to make the attack and retain any Special Rules that Weapon had.
If the Target Unit for an attack made with a Weapon that has this Special Rule includes any Models with the Vehicle Type, then this Special Rule has no effect.
Shred (X) "Attacks made with the Shred (X) Special Rule can sometimes inflict an extra point of Damage"
When any Wound Test is made for an attack with the Shred (X) Special Rule, if the result of the Dice roll, before any modifiers are applied, is equal to or greater than the value of X attached to this variant of the Shred (X) Special Rule, then if a wound is inflicted by that Wound Test , the Damage of that wound is increased by 1. Note that the Shred (X) Special Rule may only be triggered by a Wound Test and has no effect when making an Armour Penetration Test.
