I was there in ROTC when they were puttin the pressure on for the sub draft. But, my CO specifically told us that they could not tell MID's to go submarines. They tried to get me to go twice, during selection my LT said a choice for subs would be appreciated, if you're considering it to at least go have your interview. I had no interest. Then a couple months later the CO called me into his office, gave me a "personalized" letter from the NSTC Admiral that said he would really like me to consider the submarine service. Then, the CO gave me the whole run of the mill submarines is a good service spiel, and said I'd get a huge bonus (whatever they were offering at the time, somewhere around 30,000) if I agreed to go. I told him no way, and he said ok. They could tell you to go anywhere else, but you had to say ok for subs. All this was about a year ago. One of my friends who wanted to be a pilot initially got mesmerized by the bonus and jumped for the underwater shaft a year before me even though he'd never even seen a sub.
For the OC's, I had two guys in my year that had zero interest in going submarines and they were both pissed and told they didn't have a choice. The reasoning the CO gave was that their contracts when they were picked up for the STA-21 program said they would go wherever the navy needed. The ROTC contracts didn't say that, so it didn't matter if the Navy "paid for my education." Subs was, and as of last year, was still a volunteer service like it was set up to be. And like I said, I had first hand knowledge on the Officer Candidates not those who went to OCS, I just figured they get the shaft but to check that. Like they say, the two most powerful ranks in the Navy are Admiral and Midshipman. God's gift to the Navy.
