Stormtrooper officer cap.Stormtrooper officers were traditionally non-clone graduates from the Imperial Academy, but Imperial stormtroopers who proved leadership traits in combat could be ranked up to the officer mark. In battle, commissioned stormtrooper officers wore standard stormtrooper armor with rank insignia to indicate status. Non-commissioned officers were identified in the field with shoulder pauldrons instead of the standard rank squares worn over the armor. For non-combat situations, officers wore a black tunic and pants dress uniform, including a cap, boots, gloves, and standard rank squares. The stormtrooper officer rank was a stepping stone to achieving Imperial officer rank, as Stormtrooper officers were still under Imperial officers. Imperial stormtroopers also could undertake the rank of stormtrooper commander through this system of rank.
By 137 ABY, it appears that the ranking system used by clone troopers at the beginning of the Clone Wars was in use again.
