Wonder if anyone can help?? I have heard rumour that there is an official list of criteria you have to meet in order to be promoted as an adult, however no one seems to be able to tell me what the criteria are or how I can find out!! I want to know really as I been given a number of different versions of what is required!! I am now being told that I am being held back purely because of my age and that you have to be 25 to be promoted to C/Sgt. Does anyone know the truth here as I have also heard it is an advisory age bracket!! Hope that made some form of sense!!
