Wikipedia: Petty officer   
A petty officer (PO) is a non-commissioned officer in many navies and is given the NATO rank denotion OR-5. In many nations, they are typically equal to a corporal or sergeant in comparison to other military branches. Often they may be superior to a seaman, generally the (or one of the) lowest ranks in a navy, and subordinate to a more senior non-commissioned officer, such as a chief petty officer.
