I probably over reacted a bit. Sorry. But BOY it was fun!
Here's the deal. You CANNOT be forced to go subs. If you don't want to go, let them know. I know of at least one guy who got to the boat, and decided he just could not hack it. There is less shame in changing your mind now than when people's lives rely on you.
Did you take sub pay? You owe it back to them. They may or may not dock you for it, nobody on this board can answer to that. If they do not, you will live the rest of your life knowing you took money you did not earn, and probably had no intention of earning. If you did not, you should be able to serve on the surface fleet.
Going against both naval tradition and Boomer Pride, let me say that surface ships are as needed as anything else in this nations arsenal. We need bird farms on the surface of the pond as well as sewer pipes in the lower regions. If you decide to go topside, feel proud and do your job...do MORE than your job...walk tall and serve well. You are about to embark on a mission that few men could handle. Simply by volunteering you have demonstrated some character, and I can respect that.
