Well, reevtments are pretty well-maintained.... You can put all kinds of junk behind them, but they're pretty bare where the aircraft is parked...
I might also go US base with a Nissen hut US plane maybe some pilots lounging around and the Frank as a junked plane airfield being repaired by a Japanese dozer driven by US and add some palm trees {more a baa baa black sheep setting}
Well, you can compress some stuff on dioramas to include things that are a ways away, but you have to keep it to a mnimum....
Even on TV, the Black Sheep Corsairs weren't parked next to the Sheep's Pen... Nissen Huts were around, but that was later in the war, circa late 1943... Most buildings were the wooden Japanese ones (they weren't torn down if they were usable), and the rest of the "Quarters" were tentage, consisting the four-sided "Pyramid" tents that slept ten (or four Officers)... The mess hall (not the kitchen tents though, they were a special design) operations, and armorers/avionics shops were in GP Mediums... The rest of the maintenance was done outside, in the open...
That said, I really like the idea of a shot-up Frank getting moved outta the way by a 'dozer... You can add a ot of stuff laying around then..
