I was in the same boat as you 4 years ago. Since the new CCT standard was published, I secured another UPT slot, passed my FC1, and will begin UPT in April.
It will go a long way if you are up front with units about your past and how you now meet the requirement.
Hell, if I was you — I’d reach out to the unit that previously selected me and explain the situation. If they aren’t willing to take another chance on you and your scores are good and you’re a decent bro, you’ll get picked up elsewhere.
When is your ARNG commitment up? This seems like the biggest (yet one that can be overcome) roadblock.
