Explained: The Complete List of All U.S. Military Ranks

Before you get to basic training, most people don’t have a very thorough understanding of military ranks, let alone the ability to put them in order. Everybody recognizes the ones that commonly show up in movies like sergeant, captain, or admiral, but where they fall on the pecking order of different branches isn’t all that clear. And as those of us that have spent time in uniform can attest, having a good understanding of military ranks in the order of authority for our own branch doesn’t necessarily mean you know how the rank structure looks in the sister branches.

Confusion about the order of military ranks can be made even worse from branch to branch by the common use of some easily-recognizable rank names (like sergeant or captain) for entirely different pay grades. A captain in the Marine Corpss pay grade is O-3, whereas a captain in the Navy is an O-6, as one shining example.

So whether you don’t know any of the military ranks, or you’re just confused about how to put them in order, here’s a breakdown of the rank structure in each branch, starting at the most junior enlisted pay grade, and ascending up to the senior most commissioned officer. This list includes the military ranks in order for the Army, Air Force, Navy, Marines, and Coast Guard. Currently, the Space Force is largely made up of Air Force personnel utilizing the Air Force rank structure.
