... Private's Rank Insignia ...

Private (PV2) is the "cadet rank" of the Army. Members who join the Galactic Empire, but have yet to pass their training requirements hold this rank until their graduation from the Imperial Academy and placement within an Imperial Army unit.

Upon graduation, Privates will be promoted to the rank of Private First Class and join the active units of the Imperial Army.
