Can anyone help please? I have just read the 'TA Officer' publication and pages 26-27 indicate that if one joins an INDEPENDENT UNIT then the commissioning process includes attending the TCB Briefing & TCB Main Board. However, it goes on to say that if joining a SPECIALIST UNIT (i am interested in joining the AGC as an RMP Officer. I'm a CID detective in civilian life) you attend the unit for an interview where your basic aptitude & level of education, etc is assessed before being accepted as an Officer cadet to complete the basic training. Does this mean that if one joins a SPECIALIST TA UNIT as an officer they don't have to go through the TCB process?
