Cadet Non-Commissioned Officers (NCOs)...
Corporal is the first NCO rank, and can be achieved after approximately two years as a cadet. The rank of Corporal is referred to as a Junior NCO (JNCO). The Corporal acts as the liaison between Cadets and NCOs. Any cadet who is ranked 1st Class or above is eligible to become an NCO. The promotion to Corporal is made by individual Squadron Commanding Officer, and selection is based on merit and leadership potential.
Sergeant is the first Senior NCO (SNCO) rank. Cadets may be promoted to Sergeant after only one year as a Corporal. Promotion to this rank is made by the Squadron Commanding Officer.
This is the highest rank appointment that can be made by a Squadron Commanding Officer. In any Squadron which is split up into flights, a Flt/Sgt would be expected to be in charge of one flight.
Cadet Warrant Officer
Promotion to CWO can only be made by a Wing Commanding Officer. In order to be a CWO you must be over the age of 18, and most Wings insist that you be a Staff Cadet first. A CWO is not normally in charge of a flight, but instead takes charge of all the flights in a squadron.
