What is the highest enlisted rank listed?

The highest enlisted rank listed is Sergeant Major, as this position holds significant authority and leadership responsibilities within the military hierarchy. Sergeant Major is typically the senior enlisted advisor at the battalion level or higher, and this rank is involved in mentoring junior enlisted personnel, advising commanding officers, and overseeing various aspects of unit operations.

In contrast, the Sergeant and Corporal ranks are lower in the hierarchy. A Sergeant represents a leadership role but is below that of a Sergeant Major, and Corporal is often considered a junior non-commissioned officer position. While the ranks of First Sergeant and Sergeant Major may sound similar, the First Sergeant typically serves within a specific company and is responsible for the enlisted personnel of that unit, whereas the Sergeant Major often holds a broader, more encompassing role across various domains in the military structure. Thus, the distinction in responsibilities and authority confirms that Sergeant Major is indeed the highest enlisted rank listed in this context.
