I've seen a bajillion films and TV shows where Airforce generals' offices were packed with model aeroplanes. It's also very much a Star Trek tradition - Enterprise models in the TNG conference lounge, the Stargazer model (sometimes replaced with a TMP Enterprise) in Picard's ready room, the Daedalus-class ship in Sisko's office etc.And, I don't understand why an Admiral would have a collection of models in his office. i would think this would be something you would have in a home.
