Biden.

I was on /all, I fucked up. Go easy my dude.

They're also fun, but I just like 45. It's a nice chunky round.

Underway? Joke? Definitely the Coast Guard then. That, or potentially the Navy, which would also make sense, but I'm going with the coast guard.

Without going into profile history, and assuming American, I'm guessing a land based service, either the Army or Marines. Seeing as the Marines had M16s longer than the Army did. I'm going with Marines.

That said, I have a hunch you might be European somehow. Maybe Germany from how you misspelled Mossberg? You'd have to be NATO, but I'm not super knowledgeable about the German services.

Hold on, you were trained on a shotgun and a handgun? No rifle? Are you a cop?

Neat, the M9 is a good choice, and 9mm is plentiful and cheaper than 12 gauge.

I don't think it's about the word fuck. If you didn't get the union involved, you'd probably had one conversation about it, and be done with it.
