Welcome to the forums. You will be a good source of info for all things BUFF, I'm sure.
Thank you for your service.
I would suggest that you start with a scale model of your dio.
Maybe build it up around a 1/144 aircraft. It will really help as far as arranging the main subject, any part of the runway or taxiway or hardstand you choose, any buildings, vehicles, figures, and of course snow!.
