FILE - In this July, 2, 2003., file photo, a U.S. Marine Corps amphibious assault vehicle drives past a marked endangered species area as a black-necked Stilt, flies overhead at Red Beach on Camp Pendleton Marine Corps Base, Calif. Marines are training in seafaring tanks for the first time since nine men died when when one of the troop carriers sank off the Southern California coast during an exercise on July 30, 2020. The Orange County Register reports Marines from Camp Pendleton resumed exercises in water recovery and troop transfers, without troops in early April 2021. The Marine Corps has said that last year's accident was caused by inadequate training, shabby maintenance and poor judgment by commanders. (AP Photo/Denis Poroy, File)
