Ahh I thought so. They had a similar thing in the uk. I was allowed to do anything apart from anything to do with submarines as Im dual nationality. Even tho my second is US they only let sole UK nationals work on them.
Was kinda bummed out about that, the submariners get a 5k golden handshake when they pass thier training here.
I wasn't eligible for officer commission either as I diddnt have a degree, but they had a program called the articifer (spelled that wrong) program that was basically a sped up enlisted course where you attain the junior and senior ranks while they put you on day release to attend university. Sounded good. So I said fuck it I'll do that. Then I changed my mind and wound up joining a year later and they had axed the program. It's a shame really, it was a good gig, the pay was structured over the 4 years and not as good as it would be if you attained rank normally but you got a degree and a commission at the end. Should have done it
