Space Wolves - Order of Battle: The Space Wolves have a unique organisational structure that is quite different from that of a Chapter that follows the dictates of the Codex Astartes. Rather than being made up of 10 companies of 100 Astartes each, the Space Wolves consist of 12 Great Companies which contain Astartes of varying and often irregular strengths. Each Great Company is based in The Fang, the Space Wolves' Fortress-Monastery on Fenris and is led by an officer known as a Wolf Lord, equivalent to a standard Space Marine Captain, who answers only to the Great Wolf, the Chapter Master of the Space Wolves.Each Great Company is a fully self-contained army, with all the troops, vehicles and wargear necessary to make war, as well as the spacecraft required to transport its troops and vehicles. Each Great Company is far more autonomous than a Codex-compliant Astartes company, and maintains its own forges, traditions and customs. The size of each Great Company is unknown but the Space Wolves Legion was said in ancient times to be one of the smaller Space Marine Legions, which may have affected the present-day Space Wolves if they maintained a similar structure to their forebears of the Great Crusade and Horus Heresy eras. As each Great Company now serves as an independent, largely autonomous military force from its fellows, they each maintain a much larger number of Astartes than a Codex-compliant company, which accounts for why the Space Wolves Chapter is far larger than most other Adeptus Astartes units.Each Great Company is made up of a number of Packs that function much like a standard Space Marine Squad. However, their tactical usage varies greatly. Each Pack is unique in that it does not ever receive reinforcements, making the more veteran Packs smaller in number compared to a Pack of inexperienced Blood Claws. Many Blood Claw Packs start with as many as fifteen Astartes. However, losses take their toll, and by the time the members of a Blood Claw Pack become Grey Hunters, normally only 9 or 10 Space Marines are left. As they age, further losses limit the Pack sizes of Long Fangs to just 5 Astartes or less.One of the 12 Great Companies is that of the Great Wolf, the Space Wolves' Chapter Master. The Company of the Great Wolf has a similar organisation to the other Great Companies, but additionally includes the Chapter's Wolf Priests, Wolf Scouts and Dreadnoughts. Vehicles and aircraft are not listed in each Great Company's organisation as the Space Wolves maintain all of the Chapter's vehicles in a common pool at The Fang, dispensing them as needed to each Great Company depending on the tactical profile of their various assignments.Canon Conflict Note: In earlier editions of Warhammer 40,000, the Company of the Great Wolf was a separate body that existed in addition to the 12 Great Companies and essentially acted as a headquarters unit.The following represents the established order of battle of the Space Wolves Chapter as of ca. 999.M41 before the birth of the Great Rift and the start of the Era Indomitus. Unlike other Adeptus Astartes orders of battle, exact numbers cannot be given, due to the constantly shifting and irregular numbers that are a result of the Space Wolves' unique traditions and way of war.
