[Sailor Steve]

And I disagree. I was just a 'rating', and I wasn't fully qualified either. But then I wasn't a petty officer either. I was a guy who went through Radio School, then got to the fleet and found that what I had learned was tthe basic bottom-of-the-barrel stuff I needed to know to have a vague idea of what was what. The 'non-qualified' group are represented by the common sailors in the game, who are indeed green. A petty officer only gets that way by service and by proving his qualification. There is no such rating as 'Petty Officer'. He is a Radioman 3rd Class. He is a Torpedoman 1st Class. He is a Machinist 2nd Class.

Just like the army. A soldier may be green or he may be more experienced than his officers. A sergeant isn't just another grunt. He earned those stripes. A petty officer may be the only qualified man in his division, but he knows his job. Otherwise he isn't a petty officer.
