Changes

These titles are used by many Chapters, notably the [[Ultramarines]]{{Fn|1b}}. It should be noted, however, that some Chapters utilise some of these titles but not others (e.g., the [[Blood Angels]] have the postitions positions of Master of the Watch, Master of the Marches , and Master of the Recruits, but all other Company titles are unique{{Fn|5}}) and that those who do use these titles do not always follow this exact layout (e.g., the [[Salamanders]]' Master of the Recruits is the Captain of the 7th Company, rather than the 10th, and the Blood Angels' Master of the Marches is the Captain of the 7th Company, not the 5th{{Fn|5}}).
