Enlisted (sailors in-game) personnel IRL who don't remain in the enlisted ranks as NCOs in their career usually become Warrant Officers or Commissioned Officers, but not both, seeing as that's rather pointless.

Warrant Officers are specialists in their specific designator, such as ordnance (in the case of my dad), and come from the enlisted ranks where as Commissioned Officers are more general or broad in their duties.

Forgive me if I made an error, but I believe all of that is fact.


Ok, now to make sense out of that.
Yes "Sailors" can be promoted to "Petty Officers"
No "Petty Officers" can't be promoted to "Officers"
