On the face of it this is just the next straw to go....
Civilian Qualified Instructors are fairly endemic across the fleets now.
I guess someone somewhere deems it more economical to fund the individual with all through life employments costs, plus a healthy profit to the organisation he/she works for; rather than just properly man the services such that they are self sustaining.
It is a gradual further erosion of SQEP within the services as once civilianised the blue throughput constricts to suit ergo further lack of people in uniform and further reduction of SQEP; and just another civilian position with attractive renumeration and TOS that will further erode retention.
