Three AAVs and a rescue boat were in the water Thursday night conducting amphibious training between 1,000 and 2,000 yards from San Clemente Island, Lt. Gen. Joseph Osterman, commanding general of I Marine Expeditionary Force, said during the press conference.
When one of the AAVs began taking on water on its way back to the ship, the troops aboard signaled the rest of the unit and immediate response was provided by the rescue boat and two other vehicles.
Eight Marines were rescued, but one later died from his injuries. The Marine Corps has not released his identity, pending 24 hours of family notification. Two other Marines who made it out of the vehicle are undergoing treatment at Scripps Memorial Hospital and the other five have returned to their ship.

The AAV, initially fielded in 1972, remains the primary general-support armored personnel carrier for U.S. Marines.
