In the Army, pay grade shows the level of responsibility, and sometimes two ranks share the same pay grade. For E-4, the two ranks are Specialist and Corporal. Corporal is the first-line leader type of role, while Specialist is more focused on technical duties, but both hold the same pay grade, E-4.

The other ranks listed map to different pay grades: Sergeant and Staff Sergeant are higher (E-5 and E-6), and Private and Private Second Class are lower (E-1 and E-2). So the two ranks that constitute the E-4 pay grade are Specialist and Corporal.
