O ganger have shorter duty cycles. They usually (at least, did) have 2-3 years at sea then cycle to a nice shore gig, like at point loma, CA...that sound pretty nice, now doesn't it? Except I don't think they have base housing at the Point. So, Ogangers have much better rotations then enlisted, but the on the sub he will spend most of his time deployed or on the sub.
You are not going to live in some Fatt neighborhood having ice cream socials every sunday if that is what you want. YOu will not have a chance at a career because you will need to move every couple of years. Oh, and the money is not very good (unless that has changed).
Other then that.....
