Warrant officer

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.

The name of the rank originated in medieval England. It was first used during the 13th century, in the Royal Navy, where warrant officers achieved the designation by virtue of their accrued experience or seniority, and technically held the rank by a warrant, rather than by a formal commission (as in the case of a commissioned officer). Nevertheless, WOs in the British services have traditionally been considered and treated as distinct from non-commissioned officers.

Warrant officers in the United States are classified in rank category "W", which is distinct from "O" (commissioned officers) and "E" (enlisted personnel). However, chief warrant officers are officially commissioned, on the same basis as commissioned officers, and take the same oath. US WOs are usually experts in a particular technical field, with long service as enlisted personnel; in some cases, however, direct entrants may become WOs—for example, individuals completing helicopter pilot training in the US Army Aviation Branch become flight warrant officers immediately.

In Commonwealth countries, warrant officers have usually been included alongside NCOs and enlisted personnel in a category called other ranks (ORs), which is equivalent to the US "E" category (i.e. there is no separate "W" category in these particular services). In Commonwealth services, warrant officers rank between chief petty officer and sub-lieutenant in the navy, between staff sergeant and second lieutenant in the army, and between flight sergeant and pilot officer in the air force.

Modern usage[edit]

Australia[edit]

The Royal Australian Navy rank of warrant officer (WO) is the Navy's only rank appointed by warrant and is equivalent to the Army's WO1, and the RAAF's warrant officer. The most senior non-commissioned member of the Navy is the Warrant Officer of the Navy (WO-N), an appointment that is only held by one person at a time.^[6]

The Australian Army has two warrant officer ranks: warrant officer class two (WO2) and warrant officer class one (WO1), the latter being senior in rank. The equivalent rank of WO2 in the Navy is now chief petty officer, and the RAAF equivalent of the Army's WO2 is now flight sergeant, although in the past there were no equivalents. All warrant officers are addressed as "sir" or "ma'am" by subordinates. To gain the attention of a particular warrant officer in a group, they can be addressed as "Warrant Officer Bloggs, sir/ma'am" or by their appointment, e.g. "ASM Bloggs, sir/ma'am". Some warrant officers hold an appointment such as company sergeant major (WO2) or regimental sergeant major (WO1). The warrant officer appointed to the position of Regimental Sergeant Major of the Army (RSM-A) is the most senior enlisted soldier in the Australian Army and differs from other Army warrant officers in that their rank is just warrant officer (WO). The appointment of RSM-A was introduced in 1983. The rank insignia are: a crown for a WO2 (or a crown in a square on AMCU (camouflage uniform) rank slides); the Australian Commonwealth Coat of Arms (changed from the Royal Coat of Arms in 1976) for a WO1; and the Australian Commonwealth Coat of Arms surrounded by a laurel wreath for the RSM-A.^[7]^[6]

The Royal Australian Air Force rank of warrant officer (WOFF) is the RAAF's only rank appointed by warrant and is equivalent to both the Army's WO1 and the Navy's WO. The most senior non-commissioned member of the RAAF is the Warrant Officer of the Air Force (WOFF-AF), an appointment that is only held by one person at a time.^[6]
