YES!
Sax testified that the city of Haditha, where the killings occurred, was rife with insurgents in 2005.
The tactic of clearing rooms by tossing in grenades and following up with rifle fire was common practice in clearing homes where suspected insurgents were hiding, Sax testified.
His testimony echoed many of the prosecution's witnesses, who have said that they thought the insurgents responsible for the bombing that killed Lance Cpl. Miguel Terrazas were inside the homes where the civilians died.
Several members of Wuterich's squad have testified that they believed small-arms fire was being directed at the Marines from at least one, if not more, of the homes near the site of the bombing.
"If I feel my life is in danger I can apply deadly force," Sax testified before the jury of four officers and four enlisted men that will decide Wuterich's fate.
