Cadet (Cdt):
This is the standard rank you are at, once you join the ATC.
Corporal (Cpl):
This rank is the first promotion you will receive as a cadet. This means you are a Junior NCO (Non-Commissioned Officer). You responsibilities are increased two fold, and you may be involved in teaching lectures, showing youngsters the ropes and generally being a good role model for young aspiring cadets. The corporal is labelled with a specific two-chevron badge on his left and right epplet.
Sergeant (Sgt):
As a promoted Corporal, you are a Sergeant and you are a Senior NCO who is expected to be much more responsible as a sergeant than as a Corporal. You have authority over Corporals and Cadets. However, you are on the same plane as other fellow Sergeants. The Sergeant can be spotted by three chevron symbols on a badge on both left and right epplet.
Flight Sergeant (FS):
The next stage up from Sergeant is Flight Sergeant. This rank is highly respected, even more so than Cpl and Sgt. FS have acheived a lot of success through their ATC life. The rank slide worn on the shoulder straps by FS is three chevrons (^) and a crown above them.
Cadet Warrant Officer (CWO):
As a CWO, you have reached the final cadet rank of the ATC. The CWO's of a sqn are the head honcho's, top dogs, in terms of cadets ranks. Very few attain this rank. If you reach this rank by the age of 20, you can remain in the ATC for 2 more years as a cadet. There is usually 1 CWO on a squadron. But in some cases, this differs. At 492 there are three. They do not wear chevrons on their shoulders but a crown motif instead. They sometimes where a peaked hat.
