{{stub}}{{SMPortSpaceMarinesPortal}}A '''Codex Chapter''' of [[Space Marines]] tends to follow the strict organisation and doctrines as laid in the [[Codex Astartes]]. The [[Ultramarines]] are the quintessential example, and most of their Successor [[Chapters]] follow their examplestructure. Other chaptersChapters, like the [[Dark Angels]], have relatively minor variations in their organization organisation and ways of fighting. Yet others, like the [[Space Wolves]], simply ignore the organization organisation presented in the Codex Astartes and follow their own ways.

==Variations==The variations a Codex Chapter can exhibit are generally ideological differences - for example, while the Codex Astartes makes provisions for hiding chapter Chapter colours in the name of stealth, some chapters Chapters stubbornly bear their colours, as they wish to proudly display their affiliations.Some variations are unintentional; for example, more recently established Chapters may not have access to [[Dreadnought]]s or [[Terminator]]s. ==Notable Codex Chapters==* [[Blood Ravens]]* [[Imperial Fists]]* [[Novamarines]]* [[Raven Guard]]* [[Ultramarines]] ==Notable Non-Codex Chapters==*[[Space Wolves]]*[[Black Templars]]*[[Iron Hands]]*[[Dark Angels]]*[[Salamanders]]*[[Grey Knights]]*[[Deathwatch]]*[[Ashen Claws]]
