Which of these is a rank above E-7?

The rank of Master Sergeant is indeed above E-7 in the military pay grade system. E-7 typically refers to the rank of Sergeant First Class in the Army, while Master Sergeant represents E-8, the next level up. Master Sergeants hold more responsibilities and often serve in higher leadership positions, overseeing junior staff and contributing to the management and strategic planning within their units.

In contrast, the other ranks listed – Staff Sergeant, Corporal, and Private First Class – fall below E-7 in terms of hierarchy. The Staff Sergeant, for example, is E-6, while Corporal and Private First Class are E-4 and E-3, respectively. Therefore, Master Sergeant being at E-8 is what solidifies its position as the correct choice in this context.
