Officers must think above their current rank

Professional confidence means more than acting imperiously or copying the manners of a senior rank. Midshipmen, lieutenants, commanders, and captains should already understand the problems handled one level above them. A department head needs to see the tactics of the whole ship, while a commanding officer must grasp the regional strategy and wider geopolitical purpose of a deployment. Modern ships may place command in ranks once associated with narrower duties, but the burden of thought does not shrink with the title. Greenwich’s evolution from hospital to naval college therefore fits the institution’s wider message of responsibility and preparation.
