David Marquet was a Naval Academy graduate selected for command of a submarine that was known for poor morale, poor performance, and the worst retention in the fleet. Marquet was a submariner trained on a different class of sub, and quickly realized that his inexperience and his crew’s culture to do exactly what they were told was a potentially deadly combination. This book looks at the need for leadership at every level and the powerful model of giving control to subordinates and creating leaders.
