Primary Professional Military Education (PPME) (Enlisted) Block 2 Practice Test

E-6 denotes the Staff Sergeant in the Army's enlisted ranks. The Army uses an enlisted pay grade system from E-1 to E-9, where the number reflects level of responsibility and pay. At E-6 you’re a mid-level noncommissioned officer who typically leads a squad or team and serves as a technical expert and mentor to junior soldiers. This places you above E-5 (Sergeant) and below E-7 (Sergeant First Class). Officer ranks use the O pay scale, so a Captain is O-3 and a Major is O-4, while Private is the entry-level E-1. So linking E-6 to Staff Sergeant is the correct description.
