At the higher level of the military, at least, they know almost all Americans will get Covid-19. So to say people who have had it are "banned from joining" wouldn't really make sense. But yes, for now perhaps it is true. Someone who's had it vs someone who'll get it later, not sure why you chose the later. I guess if re-infections continually weaken the person, the later will be stronger. But then you have the unknown of how badly it effects them since they haven't had it yet.
