July 31 (UPI) -- A Marine Corps member died and eight are missing after an amphibious assault vehicle took on water in a training exercise in California, officials confirmed Friday morning.
Eight people were recovered, two of whom were hospitalized, one in critical condition.
Search and rescue operations involving ships and helicopters continued on Friday for the missing personnel, and the name of the deceased Marine was withheld until family could be notified.
"1 Marine has died, 8 service members remain missing and 2 were injured after an AAV mishap July 30 off the coast of Southern California," 1 Marine Expeditionary Force said Friday morning on Twitter. "All are assigned to the 15th MEU [15th Marine Expeditionary unit].Search and rescue efforts are still underway with support from the Navy and Coast Guard."
The AAV, a tracked vehicle used to deliver troops from ship to shore, was operating with the Amphibious Ready Group attached to the USS Makin Island in a routine training exercise at the time of the incident.
The vehicle is currently being phased out in favor of a newer version called the amphibious combat vehicle.
