War engine formations
Many war engines (such as the Imperial Warlord Titan) are so large and powerful that they operate independently — they act as a formation comprised of a single unit. All of the usual rules for formations apply.
Some lesser war engines (such as Baneblade super heavy tanks) may operate together in formations of more than one unit. These formations are just like any other formation except that their coherency distance is greater. To calculate the coherency distance of the formation's units, multiply the usual 5cm by the initial damage capacity of a single unit.
Baneblades each have a initial damage capacity of 3; so each Baneblade is in coherency as long as it is within (5cm x 3) = 15cm of another Baneblade.
FAQ
Q. How do formations that contain war engine and non-war engine units form a chain to be in formation coherency?
A. Every non-war engine unit must be within 5cm of at least one other unit while war engine units must be within a distance equal to their initial damage capacity × 5cm of at least one other unit.
