In Brazil, a non-commissioned officer is called "Graduado" and includes the ranks from corporal to sub-lieutenant (or sub-officer in the Brazilian Air Force), the latter being equivalent to warrant officers. All NCOs within the NSW Police are given a warrant of appointment under the Commissioner's hand and seal.Īll officers within the Australian Defence Force Cadets are non-commissioned, with ADFC officers appointed by the Director-General of their respective branch. The ranks of probationary constable through to leading senior constable are referred to as "constables". In the New South Wales Police Force, NCOs perform supervisory and coordination roles. In the Australian Army, lance corporals and corporals are classified as junior NCOs (JNCOs), sergeants and staff sergeants (currently being phased out) are classified as senior NCOs (SNCOs), while warrant officer class two and warrant officer class one are classified as warrant officers (WOs).

Their advice and guidance are considered particularly important for junior officers and in many cases to officers of all senior ranks. Senior NCOs are considered the primary link between enlisted personnel and the commissioned officers in a military organization. NCO training and education typically includes leadership and management as well as service-specific and combat training. Additionally, they are the leaders primarily responsible for executing a military organization's mission and for training military personnel so they are prepared to execute their missions. The non-commissioned officer corps has been referred to as "the backbone" of the armed services, as they are the primary and most visible leaders for most military personnel.
