Which rank is associated with E9 in enlisted ranks?

• A. Captain
• B. Sergeant Major
• C. Sergeant First Class
• D. Staff Sergeant

Answer: (B)

In this context, the key idea is the enlisted pay grade system, where E-9 stands for the highest level of enlisted service. That pay grade is reserved for the most senior noncommissioned officers. Among the given options, the rank that corresponds to this level is Sergeant Major. This rank signifies a senior enlisted leader who advises senior leaders, oversees standards, training, and discipline, and sits above lower enlisted grades such as Sergeant First Class (E-7) and Staff Sergeant (E-6). A Captain, by contrast, is a commissioned officer (O-3), not an enlisted rank. So Sergeant Major is the correct match for E-9.
