Actually I started the post. Not complain, but more out of curiosity. Since I got out a while ago and like to check in and see how the trade is.
  I did the SAC course, qualified and then did the job for 2 years before I got out. I can't speak for everyone, but being an NCIOP for 6 years, then a SAC for another 2, I did it for the challenge. Once you have pretty much mastered ASPO, AIRO, TrackSup, manual plotting(yes, I did a lot of time on steamers before they were decommissioned)etc, it was the best way to get a challenge. Keep in mind, I was in at the height of the promotion and pay freezes in the mid-nineties, so a little help on promotion when the trade opened up was definitely a thought in my mind.
  All that being said, I have met a lot of MARS officers in my day, not to make this out as a officer bashing thread, but there is just no competing with an NCIOP that has a minimum of 4-5 live radar/tactics/CCS years(~avg) experience VS a bridge watch-keeper with less than 12 months watching a Sperry or Sea Giraffe every once in a while, studying navigation, not combat tactics.
  This is not the navy of the 1700s. If they want competent, well educated NCMs they need to give them something the get them and keep them. As you stated, most if not all the other trades have core trade specialties. This was ours and as a trade we were well-suited and good at it. Why take it away? Because it's too demanding?? Trust me I remember many a watch looking at at ADLIPS for 9-12 hours straight, because we couldn't turn over while in action. Getting off watch and everything was green(steak, potatoes, bulkheads, etc).
  I may be a little overly passionate, but this being a mostly Army forums, they have their specialties and accelerated promotions(compared to Air force and Navy). SAC was one of the perks of the trade. Reading the CF recruiting PR on the trade our "specialties" are:
Instructional Techniques, Ship’s Diver, Naval Boarding Party, NCI OP Iroquois, class Classification, Basic Submarine Qualification, NCI OP Submarine Qualification, Global Command Control Systems – Maritime (GSSC-M),NCI OP Submarine Water Sensor Operator. . Forgive me, but those are all either open to all trades that serve on ship or a requirement to sail on the ship. So, unless I am missing something they took away from the trade without thought of an alternative. Guess the SF will just continue to go around in circles with these types of things. Ho hum.
  I guess if your happy with senior hand of the watch or ORS(usually sitting in the mess while the Snr. hand's in charge) then this would be a good change for the trade.
