Hi, I've recently been selected to go to OCS this summer for the Marines. I'm doing PLC Juniors this summer, and I contracted ground. I want to go air but my OSO told me to just put down ground so I could get submitted to the board, he told me I can switch my contract to air once I've been selected. I was just wondering if this is an easy process to do, and if it is that easy to switch my ground contract to an air contract before I commission? He said that I just need to take the flight physical and do well on my ASTB and then I can switch my contract.
