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 Australian Defence Force (ADF) is the military organisation responsible for the defence of the Commonwealth of Australia and its national interests. It has three branches: the Royal Australian Navy (RAN), Australian Army and the Royal Australian Air Force (RAAF). The ADF has a strength of just over 90,000 personnel and is supported by the Department of Defence and several other civilian agencies.
Regimental sergeant major (RSM) is an appointment that may be held by warrant officers class 1 (WO1) in the British Army, the British Royal Marines and in the armies of many other Commonwealth and former Commonwealth nations, including Australia, Kenya, New Zealand and South Africa. It is also an appointment that may be held by chief warrant officers (CWO) in the Canadian Forces and warrant officers of any grade in the Singapore Armed Forces, and is a rank in itself in the Irish Defence Forces and formerly in the British Army, Royal Marines and United States Army. Only one warrant officer holds the appointment of RSM in a regiment or battalion, making them the senior warrant officer; in a unit with more than one WO1, the RSM is considered to be first amongst equals". The RSM is primarily responsible for assisting their commander in maintaining standards and discipline amongst the non-commissioned members and acts as a parental figure to their subordinates, sometimes referred to by the mantra "Drill, Dress and Discipline".
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.
Sergeant major is a senior non-commissioned rank or appointment in many militaries around the world.
Airfield Defence Guards (ADG) are a mustering of the Royal Australian Air Force (RAAF) that are dedicated to the security and ground defence of airbases and other military aviation assets. Other duties include training other RAAF personnel, in skills such as the handling of small arms and infantry tactics. They do not, however, operate anti-aircraft artillery or missiles.
The chart below represents the current enlisted rank insignia of the United States Air Force.
Senior airman (SrA) is the fourth enlisted rank in the United States Air Force, just above airman first class and below staff sergeant. It has a pay grade of E-4. Between its approval on 30 December 1975 and 19 March 1991, senior airmen wore sleeve chevrons with blue center stars instead of silver to distinguish them from the non-commissioned officer rank of "sergeant", also a pay grade of E-4. The latter was abolished in 1991 and the blue center star was changed to white to conform to all enlisted rank chevrons.
Like the British Army, the Australian Army does not use the term 'enlisted' to describe its non-commissioned ranks. Instead, personnel who are not commissioned officers are referred to as other ranks. These are soldiers, non-commissioned officers (NCOs) and warrant officers (WOs). Warrant officers are appointed by a warrant which is signed by the Chief of the Army. The insignia for non-commissioned ranks are identical to the British Army up to the rank of warrant officer class two. Since 1976, WO1s and the WO in the Australian Army wear insignia using the Australian Coat of Arms.
The Royal Australian Air Force is organised into a number of operational, support and training formations located at bases across Australia.
The rank structure of the Royal Australian Air Force (RAAF) has been inherited from the Royal Air Force (RAF). The RAF based its officer ranks on the Royal Navy, and its airmen ranks on the British Army.
The Australian Air Force Cadets (AAFC), known as the Air Training Corps (AIRTC) until 2001, is a Federal Government funded youth organisation. The parent force of the AAFC is the Royal Australian Air Force (RAAF). Along with the Australian Army Cadets (AAC) and the Australian Navy Cadets (ANC), it is part of the Australian Defence Force Cadets.
The Australian Defence Force's (ADF) ranks of officers and enlisted personnel in each of its three service branches of the Royal Australian Navy (RAN), the Australian Army, and the Royal Australian Air Force (RAAF) inherited their rank structures from their British counterparts. The insignia used to identify these ranks are also generally similar to those used in the British Armed Forces.

The Australian Defence Force Investigative Service (ADFIS) is the unified investigative arm of the Australian Defence Force's Joint Military Police Unit. Initially formed in 2007 as a part of the service police until its amalgamation into the Joint Military Police Force at the beginning of 2020. ADFIS was responsible for complex and major disciplinary and criminal investigations involving the Australian Defence Force (ADF), its assets, land, personnel and capability.
A Senior Enlisted Advisor (SEA) in the United States Armed Forces is the most senior enlisted service member in a unit, and acts as an advisor to the commanding officer. Formally, E-9 billets for the senior enlisted advisor are established at Service unit, command, major command, force, or fleet levels to the SEAs/CSELs of DoD Agencies and the Senior Enlisted Advisor to the Chairman of the Joint Chiefs of Staff. SEAs are also known as Command Senior Enlisted Leaders (CSEL). Always a non-commissioned officer, the SEA is the main link between the commanding officer and the enlisted service members under his or her charge.
The Warrant Officer of the Royal Air Force (WORAF) is the senior RAF appointment for a warrant officer (WO), and therefore the most senior non-commissioned appointment in the Royal Air Force (RAF). The person holding this military appointment advises the Chief of the Air Staff (CAS) on matters concerning airmen and airwomen of the RAF. The post was created in 1996 as the Chief of the Air Staff’s Warrant Officer. The post was re-titled Warrant Officer of the Royal Air Force (WORAF) on 1 July 2021.
An officer is a person who holds a position of authority as a member of an armed force or uniformed service.

The twelfth and current Regimental Sergeant Major of the Army is Kim Felmingham.
