When Kurdish commandos went on a helicopter raid to rescue about 70 hostages who were about to be executed by Islamic State militants, the plan called for the Americans who accompanied them to offer support, not join in the action, Defense Secretary Ashton B. Carter said on Friday. But then the Kurdish attack on the prison where the hostages were held stalled, and Sergeant Wheeler responded.
“He ran to the sound of the guns,” Mr. Carter said. “Obviously, we’re very saddened that he lost his life,” he said, adding, “I’m immensely proud of this young man.”
