OCS question

Ni

My fiancé (will be husband when be leaves) goes to basic last day of the year and then OCS at Fort Benning. Has anyone done this? Im wondering how OCS will be for us and how often we will get to see each other. He has to give his hob list there. They are telling him he will have a choice on that. People who are an officer or married to one have any advice or just can give me some insight. Thanks
