HiTech also mentioned punishment for not follwing the chain of command. I'm not sure how its going to work, but it does seem he's got a good RPG factor in mind-> "Obey your wingleader, try to keep it historical and fun, stay organized, and work your way up the career"
ps) It'd be interesting if there was also a "leadership" rank... great pilots are only few, and they will be required to lead the lessers in rank and skill as a team. There should be a system which rewards the wing or the squadron where more members survive AND accomplish the mission, in contrast to those where only one super-pilot survives by abandoning all his squad/wingmen for personal scores.
