Petty officer first class

petty officer first class (PO1) is a type of rank, specifically, an enlisted rate in naval services and space forces, most notably the Starfleet of the United Federation of Planets.

A petty officer first class is an advancement of petty officer, and is one of the most basic NCO rates, a grade higher than an petty officer second class and a grade below chief petty officer in some rank structures. This grade of PO is roughly equivalent with the authority of a basic sergeant of military forces.

Petty officer first class uniform insignia existed in Starfleet, a rank insignia worn on the Starfleet uniforms of numerous eras. (FASA RPG modules: Cadet's Orientation Sourcebook, Star Trek: The Next Generation Officer's Manual)
