Still haven't caught up with the re-do of FMA so I'm not familiar with her. Is her middle name usually stated along with her given and family names? We don't *always* include middle names for characters, necessarily.

I don't know how it's handled in the re-make, actually, but in the manga they don't even refer to her by her first name that often. Usually it's just Major General Armstrong or General Armstrong. The only times I remember her other names being used were during her introduction, where they used her full name, and when she visited her family, when they only called her by her first. I suppose, based on that, you could go either way.
Sorry for the bump, but as of now, Olivier is the only one with her middle name omitted in the tags, whereas the rest of her family has theirs included (catherine_elle_armstrong, philip_gargantos_armstrong, alex_luis_armstrong).
So I support an alias or a mass edit from olivier_armstrong to olivier_mira_armstrong.
