Zoner Defense Fleet does sound a bit very on the nose, though I suppose that may be your intention. The tag looks kinda clunky, if you ask me, especially if you add a three-letter ship prefix right after. |ZDF|ZCV-Namehere is awfully front loaded. Arguably, the Z in the prefix isn't needed anymore since the faction tag already clarifies the Zoner affiliation. It would also have a smoother appearance if you dropped the first |.
That's my two cents. Glad to see someone enforcing NFZs again.
