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 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 and outerwear coats (army only). This insignia is new and never used. From my personal collection – one only $7 We are downsizing in preparation for selling and moving. Please check out my other ads. Reach out for more info.
