Chief warrant officer is a senior warrant officer rank, used in many countries. Canadian Armed Forces 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 . A CWO is senior to the rank of master warrant officer (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. Insignia 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 ranks 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 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 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. Appointments CWOs may hold a number of appointments, some of which are:
