Yes. According to NBC News, citing three U.S. officials, eight U.S. Marines were injured on September 14, 2026, when an Iranian cruise missile struck a non-Navy vessel they were operating on in the Strait of Hormuz. Officials said the Marines sustained smoke inhalation and possible concussion-related symptoms such as headaches, but were not seriously injured and all returned to duty shortly afterward. The Defense Department had not publicly disclosed the attack when it occurred; the injuries were reported days later.
