All right, do I really have to state the obvious? ....
This guy was told by his instructors to put subs on his service selection, just like I was told to put SWO on mine, and he put it down. Now I don't know about you all but how the heck do you expect a MIDN not to do what his instructors tell him in this situation? If they were like my instructors they would have told me to shut up and color. And no, that ain't exactly volunteering.
So step back and be a little more considerate, this guy has not been excessively whiny or saying that 'the Navy owes me' like others have on this site. He deserves a little more than 'tough crap, suck it up'.
As for the original poster, I would mention that you don't really want to go subs to your instructor.
