Topic: Guard or guard?
I have an elite force of guards in my story called the Elite Guard. When I want to be formal, I refer to an individual of this force as an Elite Guard, and multiple of them as Elite Guards. This is consistent with how I've seen this done in other fiction and in real life (e.g., the Pope's Swiss Guard).
But ... what do I do when I want to be informal? Can I refer to them as guard/guards, or should it be Guard/Guards? The latter looks goofy when I write it that way. A similar case comes from one of Seabrass's stories. In his case, he uses City Watchman for an individual guard and will occasionally drop City, leaving Watchman.
