"With a Weapon that has a Breaching (X) Special Rule there is a chance that a Wound Test may result in the Wound ignoring Armour Saves."
When any Wound Test is made for an attack with the Breaching (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 Breaching (X) Special Rule, then if a wound is inflicted by that Wound Test, that wound becomes a 'Breaching Wound'.

A Breaching Wound is always treated as having an AP of 2 regardless of the Characteristics of the Weapon used to make the attack.

"On a successful Charge, a Model with the Impact (X) Special Rule temporarily increases a Characteristic by 1."
If a Unit that includes any Models with the Impact (X) Special Rule or any Models that have any Weapons with the Impact (X) Special Rule, and that Unit makes a successful Charge, then this Special Rule is triggered. Once triggered, until the end of that Assault Phase, when making Melee Attacks for Models in that Unit, each Model or Weapon that is selected for one of those Models, that has a variant of this Special Rule, gains a modifier of +1 to any Characteristics that is the value of 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.
