'''The Space Wolves''' (also '''Sky Warriors of Russ''', '''Rout''' or '''Vlka Fenryka''' or - ''Wolves of Fenris'' in the [[Fenris Vulgaris|Fenrisianlanguage ''(Juvykka)'']]) were the '''VI Legion''' of the twenty [[space marine legion]]s. Their [[primarch]] is [[Leman Russ (Primarch)|Leman Russ]], and during the [[Great Crusade]] they gained a reputation as the [[Emperor]]'s executioners and instruments of punishment.{{Fn|16}} After the [[Horus Heresy]] and the resultant reforms, the legion was divided, its first and only time, into two [[chapter]]s: the new Space Wolves chapter retained the name of their parent Legion, while the second chapter took on the name of the [[Wolf Brothers]]. The latter, however, suffered from [[Mutant|mutation]] and were disbanded.

Though undeniably loyal to the [[Emperor of Mankind|Emperor]], the Space Wolves are known for their fiercely anti-authoritarian behaviour. They strongly resist the central command structure of the Imperium, and refuse to follow the dictates of the [[Codex Astartes]], which lays the structure and tactics to be used by all Space Marines. They hold a particular disdain for the [[Inquisition]], in part due to the organizations organisations purge of [[Imperial]] citizens that survived the [[First War for Armageddon]].{{Fn|15}} This culture was in stark contrast to the Space Wolves during the [[Great Crusade]] and [[Horus Heresy]], where they were known as the Sanction of the [[Emperor]], unquestionably carrying out his orders regardless of what it might be. After the [[Battle of the Alaxxes Nebula]] during the Heresy, Leman Russ decided upon forging his own path for the Wolves.{{Fn|28}}

*'''[[3rd Great Company ]] (''Tra'')''' — Known as the ''Eagle's Keepers''. Consisted of at least 9,800 Space Marines in [[Assault Squad]] and support armour roles. Commanded by Jarl [[Ogvai Ogvai Helmschrot]].

*'''[[5th Great Company ]] (''Fyf'')''' — Known as the ''Blood-Ice Storm''. Consisted of at least 10,000 Space Marines in mixed roles with light support armour. Commanded by Jarl [[Amlodhi Skarssen Skarssensson]].

Since the introduction of [[Primaris Space Marines]], the Space Wolves under [[Logan Grimnar]] have begun to reorganize reorganise themselves to accommodate these new warriors. Many of their Fenrisian titles take up roles dictated in the revised [[Codex Astartes]]. For example [[Grey Hunters]] now take up the role of [[Suppressor Squad|Suppressor]]s and [[Wolf Scout]]s serve as [[Eliminator Squad|Eliminators]]. In this way Grimnar has blended the ancient customs of Fenris with the recent changes sweeping the Adeptus Astartes.{{Fn|53b}}
