Retired General James "Mad Dog" Mattis, who went by the callsign Chaos while invading Iraq in 2003, has been nominated by President-Elect Donald Trump as the future Secretary of Defense.While he is sure to do great things as the head of the Department of Defense, Mattis spent decades in service to the United States Marine Corps, where he learned plenty of lessons along the way.The originator of axioms such as "No better friend, no worse enemy," and "Be polite, be professional, and have a plan to kill everyone you meet," Mad Dog's advice couldn't come at a better time. The military faces exceptional threats all around the globe, and leadership plays a fundamental role in keeping soldiers, sailors, Marines and airmen ready and willing to fight the enemy wherever he hides.In this video, released by the Marine Corps, General Mattis shares leadership lessons from his 40+ years of service:
