In an operation as complex and sprawling as the US military, it’s easy to be confused by who does what and who is in charge of who. Here, we’ll lay out the entire structure of the US military based on rank and pay grade. We’ll start with the enlisted, noncommissioned officers, and warrant officers, then we’ll end with the officers and generals who run the entire show. As a note, we’'ll be covering the Army in depth and list the equivalents in different branches below each role. Just know that each branch’s position is going to vary slightly.

A chart displaying all of the insignias and their roles in the US Army.

U.S. military ranks are ordered from lowest to highest and grouped into 3 categories: enlisted, warrant officers, and officers. Ranks correspond to pay grades (E-1 to E-9, W-1 to W-5, and O-1 to O-10).

E (Enlisted): What most people think of when they hear “soldier.” These are the hands-on troops and technicians.
W (Warrant Officers): The specialized experts who manage operations.
O (Officers): The leadership and management of the military.

1
Private (E-1) Enlisted soldiers make up roughly 82% of the US Army, so the majority of people in the military will fall under a role described in this section. Private (with no insignia) is a training role where the soldier is learning the ins and outs of military life.^{[1]

Private First Class (PFC) (E-3) Most soldiers reach this rank after one year and four months in training. This is the level where soldiers should know everything they need to be battle ready. They take on a larger role than other privates when it comes to team operations.

Specialist (SPC) (E-4) Specialists are technically on the same tier and pay grade as corporals, but they’re “below” corporals in terms of authority. Specialists have specific roles (called an MOS, or “Military Occupational Specialty”) that they fulfil. Picture medics, vehicle mechanics, army doctors, cybersecurity experts, etc.
