There is some grade A knobbers posting on this thread. I'll leave it to you all to work out if you fill this category.
The only thing joined up or tri-service about the 3 services at the moment is the level of backbiting and petty manouvering.
If the RN was back to the wall (it would be a first - its normally everyone else when they are about) and had Choice A - bigger impact on another service, or Choice B - bigger impact on their own service, they would take choice A everytime. Thats what the RAF have done in this case. They havent taken the choice to see off the FAA, its just basic survival.
