Message to Marines before the invasion of Iraq: “Engage your brain before you engage your weapon. . . While we will move swiftly and aggressively against those who resist, we will treat all others with decency, demonstrating chivalry and passion for people who have endured a lifetime under Saddam’s oppression.”

Message to Marines in Iraq: “Be polite, be professional, but have a plan to kill everybody you meet.”

Message to Marines in Iraq: “The first time you blow someone away is not an insignificant event. That said, there are some a–holes in the world that just need to be shot. There are hunters and there are victims. By your discipline, you will decide if you are a hunter or a victim.”

Message to Marines in Iraq: “If in order to kill the enemy you have to kill an innocent, don’t take the shot. Don’t create more enemies than you take out by some immoral act.”
