This section is one attempt to describe the entire structure and composition of the Dark Angels chapter. Every known piece of information relevant to the structure and function of the Dark Angel chapter has been brought together from all manner of Games Workshop material. Much has been based on the Ultramarines structure from the Codex Spacemarines to create the general outline. I have further added much to make this article quite plausible. This is in no way the official GW version nor is it in anyway an attempt to infringe on their IP. There are many versions of imperial history buried within the sands of time and this is but just one of them.
