I am currently in the Navy as a nuclear machinist mate and when I get out will have nine years of service. I'm currently an E-6 and looking to try out for the PJs and crossover to the Air Force at that time. I always wanted to be a SEAL, but due to my nuclear NEC that isn't possible. I've read into the prior service/ sister service requirements and they all say accessions are very limited, so my question is does anyone have any insight on this or recommendations so improve my chances of making this happen?
