Uh, sorry, but also wrong. You do need to capitalize Sailor. I don’t have any cite for proof, but I very clearly remember it coming out in the Plan of the Day, between 5-10 years ago, when I was in the Navy. It came from CNO and everything. I guess we had capitalization envy.
Oh, and sirkle? About the exact relationship between Navy and Marine Corps? Rich G7subs had it about right. They’re gonna expect you to do the dirty work for them. They’re going to snicker at you for being dumb grunts. There will be a lot of rivalry. And if you do end up guarding the nukes, virtually all of them are going to be getting paid more than you. But maybe, just maybe, if you’re lucky, the day will come when - during a drill or something - one of them won’t get out of the way in time and you’ll be fully justified in making him or her integrate very rapidly with the paint or pavement. And you’ll smile a little smile as you move on to the real objective.
Best of luck.
