Fan Casting Officer and a Gentleman in Sort by Tropes

Besides typically being a member of the upper crust, an officer and gentleman is personified by his behavior: No matter how savage the fighting, no matter how pitiless the combat, the officer almost never lets his base nature take over. He will remain polite, and even in the worst of situations will always retain his sense of propriety, often unfailingly displaying a Stiff Upper Lip. If a more clever sort, he may be a Gentleman Snarker. After all, a gentleman is not a mere label, but a way of life.
