The Air Force E9 are called chief master sergeant. The E9 in Army and Marines are called sergeant’s major. The Navy and Coast guard E8 are called senior chief petty officer. The Air Force E8 is called senior master sergeant. There is also a position in both branches for E8 known as first sergeant this is the highest ranking enlisted member in a unit. The Army and Marines E8 are known as master sergeants. The Air Force E7 is called first sergeant. The Marines E7 are known as gunnery sergeant, and the Navy and Coast Guard are known as chief petty officer. The Army E7 is called sergeant, first class. The Army and Marines start to go their separate ways when it comes to the higher enlisted ranks. The Navy and Coast Guard are called petty officer, first class. The E6 in Army and Marines are both called staff sergeants. The Air Force are called staff sergeants. Navy and Coast Guard are called petty officers, second class. The five ranks for Army and Marines are both called sergeants. The Navy and Coast Guard also consider E4’s an NCO and are called petty officer, third class. The non-NCO Army rank is called a specialist. I was a corporal for three years-the toughest three years I had in the military. You will see very few corporal ranks in the Army the corporal rank and is mainly used by combat MOS units. The Marines consider E4 as a junior NCO and a corporal. The Army and Marines have a little bit of a difference when it comes to E4. The Air Force call their E3 and below Airman. The Army and Marines call their E3 and below privates while the Navy and Coast Guard call their E3 and below seaman or airman. When it comes to military enlisted ranks each branch has both some similarities and differences. The biggest thing to know is the difference between the officers and enlisted ranks.

The Navy and Coast Guard ranks are very similar as well. The Army and Marines rank structures are very similar. One of the first things you learn in boot camp is rank identifying. An example is if you’re an electrician mate E5, your title is EM2, second class petty officer. I think the Navy has the most complicated rank system.

I guess there has to be a difference so the Marines don’t have to worry about being asked if they are in the Air Force. I have always wondered why the military branches use different military ranks instead of having them the same across the board. Military enlisted ranks have always been fascinating for me.
