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. Sergeants Major serve as the senior enlisted advisor to the commander.
The chief of staff of the Army (CSA) is a statutory position in the United States Army held by a general officer. As the highest-ranking officer assigned to serve in the Department of the Army, the chief is the principal military advisor and a deputy to the secretary of the Army. In a separate capacity, the CSA is a member of the Joint Chiefs of Staff and, thereby, a military advisor to the National Security Council, the secretary of defense, and the president of the United States. The CSA is typically the highest-ranking officer on active duty in the U.S. Army unless the chairman or the vice chairman of the Joint Chiefs of Staff are Army officers.
A chief petty officer (CPO) is a senior non-commissioned officer in many navies and coast guards, usually above petty officer.
The sergeant major of the Army (SMA) is a unique noncommissioned rank and position of office in the United States Army. The holder of this rank and position is the most senior enlisted soldier in the Army, unless an enlisted soldier is serving as the senior enlisted advisor to the chairman. The SMA is appointed to serve as a spokesman to address the issues of enlisted soldiers to all officers, from warrant officers and lieutenants to the Army's highest positions. As such, they are the senior enlisted advisor to the chief of staff of the Army. The exact duties vary depending on the chief of staff, though much of the SMA's time is spent traveling throughout the Army, observing training and talking with soldiers and their families.
Ensign is a junior rank of a commissioned officer in the armed forces of some countries, normally in the infantry or navy. As the junior officer in an infantry regiment was traditionally the carrier of the regimental colours, the rank acquired the name. This rank has generally been replaced in army ranks by second lieutenant. Ensigns were generally the lowest-ranking commissioned officer, except where the rank of subaltern existed. In contrast, the Arab rank of ensign, لواء, liwa', derives from the command of units with an ensign, not the carrier of such a unit's ensign, and is today the equivalent of a major general.
Chief Warrant officer is a senior warrant officer rank, used in many countries.
The United States Department of the Army (DA) is one of the three military departments within the Department of Defense of the U.S. The Department of the Army is the federal government agency within which the United States Army (U.S.) is organized, and it is led by the secretary of the Army, who has statutory authority under 10 United States Code § 7013 to conduct its affairs and to prescribe regulations for its government, subject to the limits of the law, and the directions of the secretary of defense and the president.
In the United States Army, soldiers may wear insignia to denote membership in a particular area of military specialism and series of functional areas. Army branch insignia is similar to the line officer and staff corps officer devices of the U.S. Navy as well as to the Navy enlisted rating badges. The Medical, Nurse, Dental, Veterinary, Medical Service, Medical Specialist, Chaplains, and Judge Advocate General's Corps are considered "special branches", while the others are "basic branches".
Pay grades are used by the eight structurally organized uniformed services of the United States, as well as the Maritime Service, 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 and chief 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.
The Singapore Armed Forces (SAF) has five rank schemes for active and reservist personnel, with a sixth for the auxiliaries of the SAF Volunteer Corps. The SAF has a unique rank structure as an integrated force, ranks are the same in the Singapore Army, the Republic of Singapore Navy (RSN), the Republic of Singapore Air Force (RSAF), and the Digital and Intelligence Service (DIS).
A bandmaster is the leader and conductor of a band, usually a concert band, military band, brass band or a marching band.
The Warrant Officer of the Royal Air Force (WORAF), previously known as the Chief of the Air Staff's Warrant Officer (CASWO), is the senior Royal Air Force (RAF) appointment for a warrant officer (WO), and therefore the most senior non-commissioned appointment in the RAF.
