It has always been drilled into every Marine that if you are attacked by some one that means to kill you, you have the right to defend yourself with deadly force, that means you can kill them to prevent them from killing you.
and it doesn't matter if a single gunshot was ever fired back at the Marines after the IED went off, they had the right and duty to attack those that attacked them using deadly force.
Sounds kinda harsh doesn't it? Our Troops are fighting an enemy that refuses to wear uniforms, hides among the civilian populace, strikes at them from inside the homes of innocent iraqis and then runs away, and yet you worry about the legality of our actions.
When is it illegal for a Marine to fight back to prevent himself or other members of his unit from being killed during an attack on them?
Never.
