Understanding the Enlisted Military Rank Structure

I'm thinking about joining the military after high school, but I'm confused about how the enlisted rank structure works. Can someone break it down, like what ranks you start at and how promotions work over time?

Sure, let's break this down. It's important to note that the rank structure varies across different branches (Army, Navy, Air Force, Marines, Coast Guard, and Space Force), but I will provide a generalized outline.

Here are the beginning enlisted ranks for most U.S. military branches:

1. E-1: Private / Seaman Recruit / Airman Basic

2. E-2: Private/Private First Class / Seaman Apprentice / Airman

3. E-3: Private First Class / Lance Corporal / Seaman / Airman First Class

For most branches, you start at the rank of E-1. Some branches, like the Army and the Marines, allow individuals to enter at an E-2 or E-3 rank if they have participated in certain programs, such as ROTC, while in high school.

After E-3, you move into non-commissioned officer (NCO) or petty officer ranks:

4. E-4: Corporal / Petty Officer Third Class / Senior Airman

5. E-5: Sergeant / Petty Officer Second Class / Staff Sergeant

6. E-6: Staff Sergeant / Petty Officer First Class / Technical Sergeant

Moving up in rank often involves a mix of time in service, job performance, and sometimes additional training or education.

From E-7 onwards, you're progressing into senior enlisted ranks:

7. E-7: Sergeant First Class/Gunnery Sergeant / Chief Petty Officer / Master Sergeant or First Sergeant

At the E-8 level, the Army, Marine Corps, and Air Force have two positions at the same pay grade. Whether one is, for example, a senior master sergeant or a first sergeant in the Air Force depends on the person's job.

The same is true for the positions at the E-9 level. Marine Corps master gunnery sergeants and sergeants major receive the same pay but have different responsibilities. All told, E-8s and E-9s have 15 to 30 years on the job, and are commanders' senior advisers for enlisted matters.

A third E-9 element is the senior enlisted person of each service. The sergeant major of the Army, the sergeant major of the Marine Corps, the master chief petty officer of the Navy, and the chief master sergeant of the Air Force are the spokespersons of the enlisted force at the highest levels of their services.

Keep in mind that these are general categories and there might be some variations between branches. For example, the Air Force and the Space Force have slightly different E-4 and E-5 rank titles.

Hopefully, this provides a rough idea of the enlisted military rank structure! It's great that you're examining your options after high school, and joining the military can be a rewarding career.
