Shred If a model has the Shred special rule, or is attacking with a Melee weapon that has the Shred rule, it re-rolls failed To Wound rolls in close combat.
Similarly, if a model makes a Shooting Attack with a weapon that has the Shred rule, it re-rolls its failed To Wound rolls.
Disruption (X) To Hit rolls of the value X indicated made by a weapon with this rule cause an automatic Glancing Hit against models with the Vehicle Unit Type instead of rolling for Armour Penetration, and an automatic Wound against models with the Dreadnought or Automata Unit Types, instead of rolling To Wound.
