How about Royal Air Force, for UK Military airfields?
It consists of yellow pushback tugs, cargo loaders, de-icers, fuel tanker and catering vehicles - all with the Royal Air Force logo on the cabin doors.
The air stairs and baggage vehicles are white and the passenger buses are silver, again with the Royal Air Force logo.
I did start trying to do this myself, but my simple mind didn't interpret the paint kit instructions very well..!
