Q:A friend asked me to answer this question: What rank is held by Carol's husband?, using the article: Lieutenant Commander Ken White orders the submarine Tiger Shark to dive to evade an aerial and surface attack. Crewman Boyer begs him to wait for the captain, Commander Josh Rice, still topside, but White refuses, and Rice (his good friend) and the quartermaster are lost. When they resurface shortly afterward, they discover that the war is over. No one other than Boyer, not even the captain's widow and father, blames him. White marries Carol and remains in the Navy after the war. Everything is fine, until one day he is assigned to show a reporter around who is doing a story about the mothballed Navy. By chance, the submarine that catches the journalist's attention is the Tiger Shark. The newsman remembers the tragic story of the last day of the war and mentions that the officer who ordered the dive "must feel like a heel", and White's feelings of guilt resurface, straining his marriage. Then Boyer is assigned to his unit. When Boyer sees White, he immediately requests a transfer. As it happens, the Tiger Shark is being recommissioned, so White sends him there. A fire breaks out on the submarine, trapping a man in a compartment. Boyer wants to charge in to his rescue, but White makes him go "by the book" and put on a protective suit first, fueling Boyer's hatred. White is about to resign from the Navy to escape the ghosts of his past, but changes his mind at the last moment. As a result, Carol decides to leave him. The North Koreans invade South Korea the same day, starting the Korean War. White is given command of the Tiger Shark. He sets sail from the Mare Island Naval Shipyard for the war as soon as the submarine is ready. Boyer is a disgruntled member of the crew., what would be the answer ?
A:
Lieutenant Commander
