Yep. Welcome to the military, where your desires are tertiary at best.
I heard Whiting was going to a set completion date model, too, but don't know for sure if that's happened.
Good luck man. And don't ask these kind of questions when you get to training. You'd be way out of your student lane. Learn your FTI, NATOPS, and FWOP and leave everything else to the instructors. You have no real control anyway, so don't even think about it.
