I am a bit confused by the connection between promotions to say, a sub O-4 and a pilot O-4.Vacancies aren't just based on discrete billet fills (13XX billets for aviation) - a large number of vancancies are also based on non-discrete coded bilets that can be filled by any URL (1050-coded) or any officer (1000-coded). Of note - though 1000-coded billets can be filled by any officer, URL is the only community that gets credit for these billets.
Are you saying that if we fail to screen the next career milestone (XO for subs, DH for aviators), then we go into a general category which selects O-4s and that a person who has done a DH tour stands a better chance of screening for O-4 than someone who hasn't? Whereas if the person does screen the next career milestone, they will promote based on that designators' needs?
