US Marine Corps Gen. James Mattis, known to his troops as "Mad Dog," is arguably the most famous living Marine.
Mattis has served from 1969 to 2013 in the Marine Corps, and during his service he built a reputation as a beloved leader, a thoughtful strategist, and a caring father figure to every young service member he encountered.
But perhaps more than anything, Mattis is known for having a way with words that manages to inspire those under his command while passing on both strong elements of humor and critical pieces of advice.
Here are a few of our favorites quotes from the Marine Corps' "Mad Dog."
