Petty officer second class

Petty Officer Second Class is the fifth enlisted rank of the UNSC Navy and is a Non-Commissioned Officer (NCO). It is equal in rank to Sergeant in the UNSC Marine Corps. This rank is given to all SPARTAN-IIs upon graduation. This is most likely due to combat situations in which a senior Marine NCO has been neutralized, allowing a SPARTAN-II to take command of a squad.

In informal settings, Petty Officers Second Class are typically called "Petty Officer".
