This episode of The Spear features a conversation with Lt. Col. Coley Tyler. In late 2004, he was a captain serving as a battalion fire support officer in Iraq. That meant that when the Marines asked for his battalion to take part in the Second Battle of Fallujah, he had an important role to play. He coordinated artillery, mortars, and fire from supporting aircraft to do something, in the Army, we call shaping the battlefield. As he describes, in Fallujah, that meant destruction.
