Testimony has started at Camp Lejeune in the investigation of two officers who led a special operations unit involved in the March shooting of some Afghan civilians.
Defense lawyers say members of the Marine special operations company will testify about how they reacted after their six-vehicle convoy was rammed by a car bomb.
As many as 19 Afghan civilians died and 50 wounded, although defense attorneys and others have said the death toll was lower. One Marine was wounded.
The administrative Court of Inquiry will focus on the actions of the unit commander, Major Fred Galvin, and a platoon leader, Captain Vincent Noble. Neither officer has been charged with a crime.
A defense attorney, Lieutenant Colonel Scott Jack says testimony will show the shooting was justified.
