All of the Dreadnoughts from the Ancients of the Fang must be fielded as a single Vehicle Squadron as described in the Warhammer 40K rulebook. However, whilst this formation includes three or more Dreadnoughts, they can all re-roll failed To Hit rolls in close combat.
Dreadnoughts from the Ancients of the Fang have the It Will Not Die special rule whilst they are within 6" of their Iron Priest.
Friendly units with the Space Wolves faction within 6" of a Dreadnought from the Ancients of the Fang have the Stubborn special rule.
