The Space Wolves only fight in packs, much as their lupine brothers and this is extended even towards their warships. By fighting as a unit, they can bring down their foes much more efficiently. All their ships must be in squadrons but instead of grouping the vessels by type (escort, cruiser, grand cruiser or battleship), the Space Wolves disregard the regular squadron rules and all the types can be mixed together. This means the Battle Barge, the Strike Cruisers and the Escorts can be in the same squadron with the Battle Barge (if available) or Strike Cruiser (if the Barge is not available) taking the role of the Alpha Dog. If the fleet is large enough (e.g. 1500 points), you can have two or three squadrons of ships. You can still choose to follow the traditional squadron rules by type but the important thing is all ships must be in squadrons
