Would the Air Forces (as high-level formations) still exist? Might they be turned into rear-area/cantonment security groups by the NATO high command? Once the planes are grounded, you've got battalions of security troops and brigade-sized support-technical groups (wings), to take over rear-area security.
P.S. You've seen this, right?
