In this age, I don’t care how tactically or operationally brilliant you are, if you cannot create harmony — even vicious harmony — on the battlefield… - Jim Mattis

We must reject any thinking of our cities as a "battlespace" that our uniformed military is called upon to "dominate." At home, we should use our military only when requested to do so, on very rare occasions, by state governors. Militarizing our response, as we witnessed in Washington, D.C., sets up a conflict — a false conflict — between the military and civilian society. It erodes the moral ground that ensures a trusted bond between men and women in uniform and the society they are sworn to protect, and of which they themselves are a part.

I think the rewards for moral courage are promotion. ... Any institution gets the behavior it rewards. Now if the institution gets rotten, you can have a problem with this. It's happened to institutions, it's happened to corporations. It's why you have to be very alert to this to keep your personal and managerial integrity.

To risk death willingly, to venture forth knowing that in so doing you may cease to exist is an unnatural act. To take the life of a fellow human being or to watch your closest comrades die exacts a profound emotional toll.
