I suppose it is a sense of historical perspective.
RAF Weston-on-the-Green can hardly be called a "base". It is most definitely a station. On the other hand, base implies a scale somewhat greater, and BZZ is probably more approaching that. The term "station" is obviously more habitual than base. I hesitate to use the term "traditional", as these things take time to evolve.
I hate to do this
, but the term station has been around significantly longer than the RAF, as a station is an Army term used to describe a location with multiple units, but smaller than a garrison. Since RAF stations housed multiple Sqns, it was appropriate with the seccession of the RFC from the Army. Same as the term "troops" really.
So for those supporting the term "station" over "base", there's implicit acceptance of "troop" too.
