Does this have any support in DS9 Homefront? Because I just remember Admiral Leyton running circles around Jaresh Inyo but just don't remember the specifics.
Yes, and it's that way in most modern democracies. The supreme chief of the armies is the democratically elected president, not some general whose motivations could be contrary to the vox populi. It was already that way in democratic Rome where general Julius Caesar acquired supreme power through essentially a coup d'etat that led to his assassination but that's another story.
