DH just got his PTS approval with a (potential) cross rate to MM/SS. He has known he wanted to cross rate for quite a while and it finally got approval just a few days ago. Although he has been trying to do so I know hardly anything about the cross rate process. I know that he will have to attend A school for his new rate and Sub school also. I was just wondering mostly if this process will start after his current enlistment is up (July 2014) or at the needs of the Navy? His current rate is severly overmanned and from what i've seen MM is not. Any information you may have as to how all this works please let me know! Thanks in advance!
