Marine Corps Gen. James “Mad Dog” Mattis is known for speaking his mind, and throughout his 40-year career, he has offered up some choice quotes.

Here are some of the best from Trump’s future secretary of defense:

On war protesters:

“When you men get home and face an anti-war protester, look at him in the eyes and shake his hand. Then, wink at his girlfriend because she knows she’s dating a pussy.”

On the importance of artillery:

“I come in peace. I didn’t bring artillery. But I’m pleading with you, with tears in my eyes. If you fuck with me, I’ll kill you all.”

Mattis delivered this gem after the invasion of Iraq in 2003 while meeting with Iraqi elders in his unit’s area of operations.

On woman-beaters:

“You go into Afghanistan, you got guys who slap women around for five years because they didn’t wear a veil. You know, guys like that ain’t got no manhood left anyway. So it’s a hell of a lot of fun to shoot them. Actually it’s quite fun to fight them, you know. It’s a hell of a hoot. It’s fun to shoot some people. I’ll be right up there with you. I like brawling.”

Mattis offered these thoughts on domestic abuse during a panel discussion Feb. 1, 2005.

On manners:

“Be polite, be professional, but have a plan to kill everybody you meet.”

Mattis gave his Marines this piece of advice while in Iraq.

On terrorist retirement:

“There is only one ‘retirement plan’ for terrorists.”

Mattis gave us this thought in 2004 while in Iraq.

On assholes:

“That said, there are some assholes in the world that just need to be shot. There are hunters and there are victims. By your discipline, cunning, obedience and alertness, you will decide if you are a hunter or a victim. It’s really a hell of a lot of fun. You’re gonna have a blast out here!

“Mad Dog” delivered this comment during a gathering of 200 Marines.

On history:

“I’m going to plead with you, do not cross us. Because if you do, the survivors will write about what we do here for 10,000 years.”
