Jocko Willink, retired United States Marine Corps General and Lieutenant General of the Army, joins Lexman to discuss the art of drilling and leadership. Jocko likens the experience of being on a battlefield to being in a polygraph exam, where your every action and reaction is monitored. He shares stories of cranium-limiting mistakes drillers make, and shows how they can be corrected with proper tactics and training. Lexman also plays some blue stones and discusses how many sacks of them it would take to fill up a golf ball bucket.
