When has Big Blue NOT required ADSCs for any requalification or formal upgrade training? Mind you, I'm ten years retired, but did AF soften up and allow formal training courses without an ADSC? Heresy!

As to your competiveness, you're competitive to get hired somewhere as long as you apply. Somebody will offer you a job, if you don't blow the interview. If that offer isn't your dream job, you can pass-not recommended-or take the job while working on making yourself that much more competitive.
Good luck, Barney Driver.
