Reaching captain or colonel normally signals substantial institutional confidence, even though some officers will still prove unable to handle the new level of complexity. Good captains need both innate mental capacity and professional development, including the ability to divide attention among mission, enemy, ship, and crew. Other officers can own individual tasks, but the captain remains the point where their reports and judgments converge. Navies therefore orient much of an officer's first fifteen to twenty years toward producing someone capable of carrying that final responsibility at sea.
