Hmmm ... good news / bad news ?? Will you eventually be fit for sub duty or is it a non-starter?
We know many Marines who changed MOS near the end of schooling. It all seemed to work out, tho. So, if you can't go subs, I hope you get a good fit for job behind door #2.
You'll get to work on your truck for a while. That will be fun. We may need to start a thread in the DITY Gallery (or here) so as you begin, we can keep up with you. (Of course, we'll also need to do a real Gallery story on the truck ... once you see her again.)
So ... with this experience in transporting a truck, shall we refer additional inquiries to you.
