I have just failed AIB for the marines with the main reason being that the board president did not think i had to motivation to become a marine period. Due to the fact i have applied for the RAF in the past and shown interest in the Army. So , i looked at Other Ranks Marine as an alternative to being an officer. Whilst looking at these i have noticed about 2 specializations that would interest me - since to the fact that being a GD Marine for a career is almost impossible. Medical Assistant being the most interesting as a career since it is much the same as a CMT in the Army. However , the issue of being assigned a specialization i don't want shouldn't bother me if i want to be a Marine , which goes back to what the Lieutenant-Colonel said about motivation. I have always wanted a job in the 'teeth arms' of the military or something directly related to it whether it be RM/RAF REG or ARMY. I really don't know what to do at the moment. Any advice or insight would be very helpful. Thank you in advance.
