'''Petty Officer Second Class''' is the fifth enlisted rank of the [[UNSC]] [[UNSC Navy|Navy]] and is a [[non-commissioned officer]]. It is equal in rank to [[Sergeant (UNSC)|Sergeant]] in the [[UNSC Marine Corps]]. This rank is given to all SPARTAN-IIs upon graduation.<ref>''[[Halo: The Fall of Reach]]'', page 99.</ref> 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".
