What is the lowest level of NCO in the Army?

The lowest level of Non-Commissioned Officer (NCO) in the Army is Corporal. The rank of Corporal is designated as E-4 in the pay grade system and serves as the initial point where a soldier assumes leadership responsibilities over other soldiers. At this level, the Corporal is expected to provide guidance, supervision, and mentorship, which are fundamental roles of an NCO. This rank highlights the transition from a lower enlisted rank to a position of increased responsibility and leadership, marking the beginning of the NCO leadership trajectory.

Other ranks listed, such as Sergeant (E-5), Staff Sergeant (E-6), and Sergeant Major, are higher in the NCO hierarchy and carry more extensive responsibilities and authority. Hence, while these ranks also perform crucial leadership functions, they do not represent the entry-level point for NCOs, which is defined by the position of Corporal.
