Few military services can claim to have officers trained as well and as diversely as the officers of the Royal Naval Service. RNS line officers are trained in navigation, engineering, military tactics, history, the sciences and armed and unarmed combat. Any line officer on a ship is qualified to pilot that ship, to run its engines, to fire its guns, to take command if necessary. Line officers start their careers in the Royal Naval Service through one of two gateways: through the Royal Naval Academy in Enaj, or by enlisting directly as a midshipman.
