TOKYO (AP) _ Three U.S. Marines were charged with negligence-related charges Friday in the death of a fellow serviceman during a military exercise in Kuwait.

Three members of Williams' 31st Marine Expeditionary Unit were charged in the December accident, said the U.S. Marine Corps in Okinawa, Japan.

Lance Cpl. Albert Ducharme, of Stony Point, N.Y., was charged with involuntary manslaughter and several other violations of military law, including failure to obey an order.

Lance Cpl. Bruce Breeden of Savannah, Ga., was charged with dereliction of duty, reckless driving and making a false statement.

Staff Sgt. William Potter, of Ashtabula, Ohio, was charged with dereliction of duty.

The unit was training in Kuwait at the time of the accident.
