IIRC the UAS studes at Nijmegen and the training events leading up to it were wearing the Royal Air Force badge above the breast pocket of their CS95. A few were wearing the TRF as well on the shoulder.
UOTC cadets have it easier as I believe they are issued with rank slides with UOTC embroidered on the bottom. They wear the TRF of the regiment they're attached to.

They lad asked a pertinent question and has recieved some useful gen in return. The fact that he's asking these questions means he is filling his life with something meaningful in the hours inbetween alcoholic stupor and pubrise, something which you should probably do too.
