Which ranks are classified as Non-Commissioned Officers (NCOs) in the Marine Corps?

In the Marine Corps, Non-Commissioned Officers (NCOs) are typically recognized as those ranks that hold responsibilities for leadership and supervision of junior enlisted Marines. The ranks classified as NCOs are Corporal and Sergeant.

A Corporal serves as a first-line leader and plays a crucial role in mentoring and guiding junior Marines, while a Sergeant has increased responsibilities that include command over small units and more extensive supervisory duties.

Both of these ranks are fundamental to the structure of the Marine Corps, as they bridge the gap between enlisted personnel and the officer ranks, ensuring effective leadership and the enforcement of discipline and standards within a unit. Understanding these roles is critical for recognition of the chain of command and the overall operational effectiveness of Marine Corps units.
