The first time you blow someone away is not an insignificant event. That said, there are some *******s 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.

An untrained or uneducated Marine ... deployed to the combat zone is a bigger threat to mission accomplishment ... than the enemy.

I would consider the principal threats to start with Russia, and it would certainly include any nations that are looking to intimidate nations around their periphery, regional nations nearby them, whether it be with weapons of mass destruction or, I would call it, unusual, unorthodox means of intimidating them, that sort of thing.

For the mission's sake, our country's sake, and the sake of the men who carried the Division's colors in the past battles - who fought for life and never lost their nerve - carry out your mission and keep your honor clean. Demonstrate to the world there is "No Better Friend, No Worse Enemy" than a U.S. Marine.

Fight with a happy heart and strong spirit.

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

What concerned me was that [James Mattis] played not only a critical role as a battlefield commander in Fallujah, but also, afterwards, when he was promoted to various other higher-ranking positions, he served as a convening authority in court-martial proceedings against various marines who had been accused of atrocities - for example, in the Haditha massacre, where a group of marines went on a killing spree after one in their unit was killed.
