This will really only be an issue during your initial entry training, where they will wake you up at 0400 hrs or so, maybe even in the middle of the night to do some pushups. Once you are finished with "boot camp", there won't be any wake-ups. You can get up whenever you want to as long as you make it to work on time. Work will probably start at about 0700 hrs, but may be earlier if you have to do PT in the morning or something. It is very dependent on your command.
