What are the chances that I can be moved into another 68W30 slot, and are there any NC or PA Units looking for medics?

There is a newly stood up flight medic unit out of Salisbury NC hard up for medical right now.

Ideally the IST coordinator would tell you of available vacancies for you. If you want to go above and beyond that though you can call a PA National Guard Recruiter and have them send you all the vacancies in the MOS, or even just the rank and transfer into a new MOS. I have personally done it in PA.
