Depends on a lot. there is a civilian equivalent to every job in the military pretty much. there are people that spend their whole military career in an office. Which isn’t an insult by the way. There are so many things one can do, assuming you’re qualified.
I was a deckhand, I moored the ship and painted stuff. Basic seaman apprentice stuff.
Then I fore casted weather. They sent me to schooo for it, even paying me to move all over the place.
If you have specific questions ask, but I could write a book about my ten years it’s kinda hard to answer this.
