Yi Sun-sin (1545–1598) was a naval commander of the Korean dynasty, honored after his death as "Lord of Loyal Valor." When invasion swept across the sea, he took command of his nation's fleet and built — then mastered at scale — the armored "turtle ship," a vessel clad in iron that shrugged off boarding and fire alike. At Okpo, Hansan Island, and Myeongnyang he shattered far larger fleets again and again, winning where the odds said he should not. At Myeongnyang, with barely a dozen ships, he turned back a force of more than three hundred. At his final battle of Noryang he fought from the front and fell to a stray shot, leaving the words: "The fight is at its height — do not announce my death." His fleet pressed on until the invaders broke, and the East Asia remembered him as one of the greatest sea-commanders it ever produced.

On the Battlefield
Yi Sun-sin marches in the Infantry line as a tank who answers blows with blows — a living shield that punishes whoever strikes it. His battlefield gift is born of his legend: when your forces stand outnumbered, his strikes bite deeper, and the worse the odds the harder he hits. His signature blow, "Wind breaker," carves forward through the enemy front and swells in fury wherever the line is thin — a turtle ship made flesh, built to crack open the very bursts of force that should overwhelm it.
