Brotherhood of Steel chapters

What follows is a list of all known Brotherhood of Steel chapters. 
==Background==
A note on terminology: A rogue Brotherhood of Steel chapter is a division of the Brotherhood that either does not recognize the authority of Lost Hills or has significantly deviated, up to and including total abandonment of, Brotherhood ideology and the Codex. While these chapters may continue to use the name, rank system and technology of the Brotherhood, they are not seen as legitimate by the Brotherhood proper.
