Family members of a Wisconsin Marine who was killed in a training accident last year have filed a lawsuit.
19-old Evan Bath of Oak Creek and eight other service members died when the amphibious assault vehicle sank during an exercise in California.
They were trapped inside by a defective cargo hatch door.
The Bath family is suing B-A-E Systems, the maker of the assault vehicle.
They claim the company knew about the problem for years and never took steps to correct it.
Federal law prevents families from suing the U-S military.
The family is asking the Marines to stop using the A-A-V.
