I've read in other forums that advancement depends mainly on your rate. I understand that your begin as an E-3 and after A-School you become an E-4, but after that how hard is it go move up the ranks?
Second, how hard is Nuke school? I'm sure it's going to be tuff, and I enjoy a challenge, but I'm afraid it may be too hard and I'll fail out. Also, I realize that it ultimately depends on me, but excluding that factor. I just want to know how hard it is in general.
I know these are noob questions, but my recruiter sugar coats EVERYTHING and I want an honest answer.
