Yeah, I waived my dental separation check because I wanted to get my damn DD-214 and go on separation leave so I could start looking for a civilian job. We were sailing for GTMO the next day and the XO said if I didn't get out processed, I'd have to go with the ship. He was probably bluffing, because they already had orders from SECNAV directing them to process me by Sept 30 and it was Sept 23. They would have had to helo me off or fly me back from GTMO and take it out of the ship's budget. I shared a stateroom with the comm officer and I used to be one too. I told him to look out for my orders because I knew they were coming, so he made a copy for me, though the original goes to the CO/XO first for officer out processing. It's not like it was any big secret. I had a regular Navy commission and you had to resign one year in advance of when you wanted out. The the next 364 days was a big F U from the lifers to the guy getting out (me).I was in Space Command 98-02. Never got a flu shot and don't recall anyone else doing it either ¯\_(ツ)_/¯
The only annual thing I remember they requiring of us was the bicycle test.
Now that you mention that I do remember being hassled about dental checkups, but I was never forced to do that. Only went to the dentist once as part of the separation checklist.
9 months later my civilian dentist said I need two crowns and even with my work dental insurance it was $1500 I didn't have. Could have got it done at the VA if they documented it.
"Your dedicated service to your country and to the United States Navy, is greatly appreciated, and by the way pay for your own damn crowns."
