Chief warrant officer is a military rank used by the United States Armed Forces, the Canadian Armed Forces, the Pakistan Air Force, the Israel Defense Forces, the South African National Defence Force, the Lebanese Armed Forces and, since 2012, the Singapore Armed Forces. In the United States Armed Forces, chief warrant officers are commissioned officers, not non-commissioned officers (NCOs) like in other NATO forces.[1]

Canadian Armed Forces[edit]

In the Canadian Armed Forces, a chief warrant officer or CWO is the most senior non-commissioned member (NCM) rank for army and air force personnel. Its equivalent rank for navy personnel is chief petty officer 1st class (CPO1). The French language form of chief warrant officer is adjudant-chef (adjuc).

A CWO is senior to the rank of master warrant officer[2] (MWO) and its navy equivalent of chief petty officer 2nd class (CPO2).

Cadets Canada uses the ranks of chief petty officer 1st class (Royal Canadian Sea Cadets), chief warrant officer (Royal Canadian Army Cadets), and warrant officer 1st class (Royal Canadian Air Cadets). This organization's uniforms use a similar coat of arms insignia as the Canadian Armed Forces.


The rank insignia of the CWO is a simplified version of the 1957 coat of arms of Canada, worn on both forearms of the service dress tunic; in gold metal and green enamel miniature pins on the collar of the service dress shirt and outerwear coats (army only); on CADPAT slip-ons worn in the middle of the chest, embroidered in tan (army) or blue (air force) thread; and in pearl-grey thread on blue slip-ons on both shoulders of other uniforms (air force only).

The insignia lacks the annulus, from 1985 changes, behind the shield bearing the motto of the Order of Canada. It also differs from both the 1957 and 1985 versions through a lack of compartment and mantling.

Forms of address[edit]

CWOs are generally initially addressed as "Chief Warrant Officer", and thereafter as "Sir" or "Ma'am" by subordinates; and as Mr. or Ms. by commissioned officers. If they hold the appointment of regimental sergeant-major, they may also be addressed as "RSM" by the commanding officer, other officers, or when referred to in conversation. CWOs are never addressed as "Chief", this being a form of address reserved for chief petty officers. Civilians can address them as Chief Warrant Officer or CWO or Mr/Mrs/Miss/Ms (followed by surname).

Key positions[edit]

CWO/CPO1 may fulfill roles in a number of key positions (KP). These positions require the incumbent to act in an advisory or liaison role to a non-command position i.e. Assistant Judge Advocate General Liaison Chief Petty Officer, RCEME Corps Sergeant-Major, Defence Ethics Program Chief Warrant Officer.


CWOs may hold a number of appointments, some of which are:

  • Regimental sergeant-major (RSM) – the most senior NCO in a battalion-sized army unit, including armoured, combat engineer, and signal regiments.
  • Squadron warrant officer (SWO) – the most senior NCO in a squadron-sized air force units and army signal units
  • School chief warrant officers/chief petty officers (SCWO/SCPO) - the most senior NCO in air force, navy and some army schools of battalion or squadron size.
  • Base or wing chief warrant officer/chief petty officer - the most senior NCO on a Canadian Forces base or wing establishment
  • Fleet chief petty officer - the most senior NCO in either Atlantic Fleet, Pacific Fleet, or Naval Reserve
  • Ship's coxswain - the most senior NCO on an RCN ship (fulfilled by a chief petty officer 2nd class or petty officer 1st Class for minor vessels)

Due to the unified nature of the Canadian Armed Forces, it is not unheard-of for air force CWOs or even navy CPO1s – especially those of the so-called "purple trades", such as logistics or military police – to find themselves filling the appointment of RSM in what are otherwise considered Canadian Army units (such as service battalions or communication regiments). Conversely, it is not impossible for an army CWO or navy CPO1 to be the squadron CWO of a Royal Canadian Air Force squadron.

Senior appointments[edit]

Senior appointments for chief warrant officers and chief petty officers 1st class entitle the incumbents to wear a modified rank badge or an addition to the rank badge. They are as follows:[3]

Formation chief warrant officer[edit]

The coat of arms over the central insignia of the badge of the Canadian Armed Forces (crossed swords, an anchor and an eagle in flight). This appointment is given to CWO assigned to commanders at the base, brigade, wing, and division levels. Specific examples include base chief warrant officer, brigade sergeants-major, wing chief warrant officers, the division chief warrant officer (DCWO) of 1 Canadian Air Division and the division sergeant-major (Div SM) of 3rd Canadian Division (3 Cdn Div). A formation chief warrant officer would typically be seen with a colonel or brigadier-general, but may occasionally be seen with a lieutenant-colonel or major-general.

Command chief warrant officer/chief petty officer (CCWO/CCPO)[edit]

The coat of arms with a wreath of laurel wrapped around the base. This appointment is given to CWO/CPO1 assigned to commanders of commands including to the commander Canadian Special Operations Forces Command, commander Canadian Forces Intelligence Command and commander Canadian Joint Operations Command. The command chief warrant officer appointed to the commander Canadian Army is called the Canadian Army sergeant-major, while the command chief warrant officer appointed to commander RCAF is known as Chief Warrant Officer of the Air Force. The command chief warrant officer of the RCN is known as the RCN Command Chief Petty Officer. A command chief warrant officer/chief petty officer would be seen with a major-general/rear-admiral or lieutenant-general/vice-admiral.

Canadian Forces chief warrant officer (CFCWO)[edit]

Messes and quarters[edit]

CWOs generally mess and billet with other warrant officers and with sergeants, and their navy equivalents, chief petty officers and petty officers. Their mess on military bases or installations are generally named the "Warrant Officers and Sergeants Mess".


Although NCMs, CWOs generally wear the uniform accoutrements of commissioned officers; for example, officer cap badge, waistcoat instead of cummerbund with mess dress, etc.

Israel Defense Forces[edit]

Rav nagad

The רב-נגד Rav nagad, a Chief Warrant Officer is the most senior non-commissioned officers rank in the Israel Defense Forces (IDF). Because the IDF is an integrated force, they have a unique rank structure. IDF ranks are the same in all services (army, navy, air force, etc.). The ranks are derived from those of the paramilitary Haganah developed in the British Mandate of Palestine period to protect the Yishuv. This origin is reflected in the slightly-compacted IDF rank structure.

South African Armed Forces[edit]

SANDF Chief Warrant Officer rank insignia

In 2008[5] the Warrant Officer ranks of the South African National Defence Force were expanded and the rank of Chief Warrant Officer was created. In the South African Navy a Chief Warrant Officer is the senior NCO in Fleet Command. In the South African Army the equivalent is the senior NCO in an Army Formation, such as Armour, Infantry etc.

United States Armed Forces[edit]

Chief warrant officer in the United States Armed Forces refers to any warrant officer in pay grades CW2 and above. All warrant officers (WO1 to CWO5) are officers and rate a salute by all enlisted NATO other ranks personnel. The U.S. Army and the U.S. Marine Corps use WO1/WO through CW5/CWO5 as designators and the U.S. Navy uses WO1 for one specialty (cyber warfare); all other branches of the U.S. Armed Forces use CWO2 through CWO5. The U.S. Air Force, although authorized to appoint warrant officers, does not utilize those grades in any capacity. All warrant officers dine in the officers' mess but rate just below O-1 (NATO rank code OF-1).

On 4 June 2018, the Chief of Naval Operations announced the reestablishment of the rank of warrant officer one (pay grade W-1), for cyber warrant officers, and solicited applications for the rank/grade. These warrant officers will receive their appointment via warrant and not via commission. They will incur a six-year service obligation once promoted to W-1. A minimum of three-years in grade with a total service time of 12 years must be achieved before appointment and commission to chief warrant officer (W-2). However, the President also may grant appointments of warrant officers in the grade of W-1 via commission at any time as well as the Secretary of the Navy may also appoint warrant officers in that grade via commission, through additional regulations. In mid-December 2018, the Navy announced that six selectees had been named. They will wear a distinctive cap badge with two crossed anchors.

Warrant officer rank insignia is the only officers' insignia that is not the same for all branches of the U.S. military, with one exception. The rank insignia for a CW5 became the only universal insignia within the warrant officer ranks when the U.S. Navy promoted its first CWO5 in 2002 and the Army adopted the emblem in 2004.

Warrant officers in the United States are classified as officers and are in the "W" category (NATO "WO"); they are technical leaders and specialists. Chief warrant officers are commissioned by the president of the United States and take the same oath as regular commissioned officers do. They may be technical experts with a long service as enlisted personnel or direct entrants, most notably as U.S. Army helicopter pilots.
