Look at history for the future. In the early 50's and mid 60's members of the reserves were called to service for up to three years to needs of national security. These were not call ups for the Korean War of Vietman, though that did happen. Many guys filled IP and other roles stateside. I bet we will see "cherry picking" again of needed AFSCs. A change three years ago allowed individual UTC's be called up. Prior to that UTCs were tied to aircraft numbers in set CONPLANs. Not anymore. If they need a F35 IP qualified guy, just reach down to the a F35 reserve unit and grab a guy for up to three years under federal law. Its already happening in the C130 guard/reserve world with IP's (All crew positions) being sent to A-stan for one year to teach the A-stan Airforce. If your a fighter guy, AOC qualified or UAV you are at high risk. Its already be done and discussed at HHQ.
