The rank title of First Sergeant was first officially used by the Marine Corps in 1872, when it was introduced to replace Orderly Sergeant to reflect the position’s larger administrative and leadership responsibilities in relation to other Sergeant ranks at the time. By the middle of World War II, First Sergeants were in the highest pay grade (Grade 1).
But after 1 December 1946, First Sergeants—along with Sergeant Majors, Master Gunnery Sergeant, Master Technical Sergeant, Quartermaster Sergeant, Paymaster Sergeant, Maser Steward, and Master Cook—were designated as Master Sergeants. Eight years later, the Corps backpedaled somewhat and brought back First Sergeant in the new highest grade of E-7, below Sergeant Major and above Master Sergeant.
Finally, in 1958, First Sergeants were placed in the E-8 Grade along with Master Sergeants, sharing the same rocker/chevron configuration but with a lozenge in lieu of the crossed rifles introduced to enlisted insignia as a reminder that “Every Marine is a rifleman.”
