you have to remain in the army for a long period of time, at least twenty years and be in combat at least once, but that is normally not the case and you go numerous times.
Military career advancement is very unpredictable, other than that it comes faster in times of war than it does in times of peace.
General of the Army Dwight David Eisenhower
