准士官
In the South African National Defence Force, a warrant officer (WO) is set apart from those who hold a non-commissioned officer (NCO) rank. Warrant officers hold a warrant of appointment endorsed by the Minister of Defence. Warrant officers hold very specific powers, which are set out in the Defence Act and the Military Defence Supplementary Measures Act. Before 2008, there were two classes – warrant officer class 1 and 2. A warrant officer class 1 could be appointed to positions such as regimental sergeant major, formation sergeant major or Sergeant Major of the Army or Warrant Officer of the Navy. In 2008, five new warrant officer ranks were introduced above warrant officer class 1: senior warrant officer (SWO), master warrant officer (MWO), chief warrant officer (CWO), senior chief warrant officer (SCWO) and master chief warrant officer (MCWO).
