Advancement Prospects

Each military branch has 10 officers' grades (O-1 through O-10). The higher the number is, the more advanced a person's rank. The various branches of the military have somewhat different criteria for promoting individuals; in general, promotions depend on factors such as the number of years served, demonstrated abilities, advanced training, recommendations, and scores on written exams. Promotions become more and more competitive as people advance in rank. Some officers can expect to reach lieutenant colonel or commander (O-5). Outstanding individuals may be able to advance beyond these levels.
