The single leader of the Space Wolves is known as the Great Wolf. From there, breaking from Imperium regulation, they are divided into twelve "great companies." Each company contains a mixture of soldiers, including Blood Claws, Grey Hunters, and Long Fangs. The Space Wolves' disrespect for authority has been known to get them in trouble with the Imperium from time to time. However, their irreverence is only matched by their ferocity, and they are indeed the Imperium of Man's greatest asset in battle.
