Civilians can't fly pure military aircraft that aren't civilian registered or that don't have an equivalent civilian type. So: Tutors are civvy, Squirrell and 412 are civvy but mil reg, King Air is civvy but mil reg (but unlikely to teach on that anyway!) For Tutor instruction on UAS/ AEF you need to be or have been a Qualified Service Pilot.
You won't find Civilians instructing on Hawk, Tucano or any frontline types.
