Be the hunter, not the hunted: Never allow your unit to be caught with its guard down.

Since 9/11 we've been engaged in wars around the world, and General [James] Mattis has been a leading battlefield commander in many of those theaters, including in the April 2004 siege of Fallujah, where the US Marines killed so many people that the municipal soccer stadium in the city had to be turned into a graveyard for the dead.

Anyone who kills women and children is not devout. ISIS cannot dress themselves up in false religious garb and say that somehow this message has dignity. We're going to strip them of any kind of legitimacy.

You cannot allow any of your people to avoid the brutal facts. If they start living in a dream world, it's going to be bad.

Once ISIS is defeated, there is a larger effort under way to make certain that we don't just sprout a new enemy. We know ISIS is going to go down. We have had success on the battlefield. We have freed millions of people from being under their control.

We can kill lots of people. We do kill lots of people. We can destroy virtually anything we choose to destroy.

Be the hunter, not the hunted: Never allow your unit to be caught with its guard down.
