Ive done a search to see if this has been asked before and havent found anything so apologies in advance but here goes.. Im a Crafty, been in the Army 3 1/2 years and Ive been at my first unit 18 months now. I recieved my first SJAR and was strongly recommended for promotion. After keeping an eye on the Board proceedings Ive discovered that I havent gone to the board due to Insufficient Seniority. Now if this is time in rank, could someone please tell me what the minimum time in rank must be? or is it due to it being my first SJAR that has held me back? If anyone could shed some light on it for me that would be much appreciated!
