I need to rehash something. I have several guard forces in the story, referred to as the Royal Guard, the Praetorian Guard, and the Elite Guard (to replace the Candidatii, which I dislike). Rather than constantly refer to these guards as "members of" or "officers of" the Praetorian/Royal/Elite Guard, I was considering simply referring to them as Praetorian guard(s), Royal guard(s), and Elite guard(s). So, the entities are always capitalized (e.g., the Guard), but the members are always lowercase (the guard(s)). Is that enough of a distinction to be clear? Another option is to simply refer to the individuals as Praetorian Guard(s), Royal Guard(s), and Elite Guard(s) and allow the reader to figure it out from context. For ambiguous cases, I can always be explicit. Seabrass uses City Watch and City Watchman.
Thoughts?
