Warrant officer (WO) is a rank or category of ranks in the armed forces of many countries. Depending on the country, service, or historical context, warrant officers are sometimes classified as the most junior of the commissioned officer ranks, the most senior of the non-commissioned officer (NCO) ranks, or in a separate category of their own. Warrant officer ranks are especially prominent in the militaries of Commonwealth nations and the United States.
A non-commissioned officer (NCO) is a military officer who does not hold a commission. Non-commissioned officers usually earn their position of authority by promotion through the enlisted ranks. In contrast, commissioned officers usually enter directly from a military academy, officer training corps (OTC) or reserve officer training corps (ROTC), or officer candidate school (OCS) or officer training school (OTS), after receiving a post-secondary degree.
Staff sergeant is a rank of non-commissioned officer used in the armed forces of many countries. It is also a police rank in some police services.
Sergeant major is a senior non-commissioned rank or appointment in many militaries around the world.
A chief petty officer (CPO) is a senior non-commissioned officer in many navies and coast guards, usually above petty officer.
A petty officer (PO) is a non-commissioned officer in many navies. Often they may be superior to a seaman, and subordinate to more senior non-commissioned officers, such as chief petty officers.
Chief Warrant officer is a senior warrant officer rank, used in many countries.

Each officer rank in the navy of a NATO country may be compared with the ranks used by any military service in other NATO countries, under a standardized NATO rank scale. This is useful, for instance, in establishing seniority amongst officers serving alongside each other within multinational command structures.
Specialist is a military rank in some countries' armed forces. Two branches of the United States Armed Forces use the rank. It is one of the four junior enlisted ranks in the United States Army, above private (PVT), private (PV2), and private first class and is equivalent in pay grade to corporal; in the United States Space Force, four grades of specialist comprise the four junior enlisted ranks below the rank of sergeant.
Pay grades are used by the eight uniformed services of the United States to determine wages and benefits based on the corresponding military rank of a member of the services. While different ranks may be used among the eight uniformed services, pay grades are uniform and equivalent between the services and can be used to quickly determine seniority among a group of members from different services. They are also essential when determining a member's entitlements such as basic pay and allowances.
In the United States Armed Forces, the ranks of warrant officer are rated as officers above all non-commissioned officers, candidates, cadets, and midshipmen, but subordinate to the lowest officer grade of O‑1. This application differs from the Commonwealth of Nations and other militaries, where warrant officers are the most senior of the other ranks, equivalent to the U.S. Armed Forces grades of E‑8 and E‑9.
United States Marine Corps rank insignia are the devices worn by officers in the United States Marine Corps, in order to provide distinction from other ranks. Different styles of rank insignia are worn on different uniforms of the United States Marine Corps.
