For attrites/DOR Marines, you get the long process of dealing with MATSG-21 (that is the command that you get assigned to when you check in down in P-cola). If you continue through the program, you will be have a MATSG command handle all your admin/non-flying business. Word on the street is that MATSG will look at your TBS standing/choices that you wrote down (you don't take part in the MOS selection process, but you still have to put down your preferences) and see what schools have openings and how long you will sit before starting that school. You can fix this whole problem by staying in the program and getting your wings...so I would worry about the phase of training that you are in or heading to next (whether that is OCS, TBS, API, Primary, etc). Too much to worry about if you start looking too far down the road!
