Rewatching "The Enterprise Incident" last night I noticed two senior officers in the briefing room scene
I previously wasn't aware of.
It appears Commander Giotto ("The Devil in the Dark") has been replaced by a new head of security (rank of Commander) and there is also a new tactical officer of the command division (rank of Lt. Commander).
Have the names (in-universe or in real life) of these gentlemen already been established?
