Swiss Air Force aircraft squadrons

In the Swiss Air Force an aircraft is usually not deployed permanently to a given Squadron, especially that of the [milizia] pilots who spend just a few weeks a year in service. Aircraft are used across several squadrons, even the Squadron leader's aircraft such as the F/A-18C J-5017 from 17 Squadron will be used by used other squadrons. Older aircraft will often be retired from front line service to support squadrons, for example the Hawker Hunter from a fighter-bomber with 5 Squadron to [Zielflugstaffel] 12 as a target tug. The two F/A-18C Mock-up X-5098 and X-5099 are not part of any squadron. They are trainings aids for the ground-crews.
