Is it possible for a SPC 68C to do IPAP?

Yes It is possible, as long as you meet you requirements. You don’t need a bachelors degree to apply, you need at least 60 credit hours, 30 of which must be from the required prerequisites. Search for the group “interservice physician assistant program” on Facebook, it’ll be helpful. I know lots of SPC (regardless of MOS) that have been accepted.

You dont need bachlors. Go read requirements on ipap site
