Twin-Linked If a shooting weapon has the twin-linked special rule, or is described in a model's wargear entry as twin-linked, it re-rolls all failed To Hit rolls.
For a Blast weapon, if the scatter dice does not roll a hit, you can choose to re-roll the dice with a Twin-linked Blast weapon. If you choose to do so, you must re-roll both the 2D6 and the scatter dice.
Twin-linked Template weapons are fired just like a single weapon, but must re-roll failed To Wound rolls and armour penetration rolls.
Ardex Machina This weapon may fire Overwatch attacks even though the model to which its attached to may usually not do so, so long as it is within the firing arc of the charging models and, in addition, carries out all Snap Shots at BS 2.
