Rob O'Neill and Dakota Meyer are two of the most decorated and recognized US service members: O'Neill killed the world's most wanted man, Osama bin Laden, and Meyer was the first living Marine to receive the Medal of Honor since the Vietnam War. In this book, O'Neill and Meyer share their philosophy of combat and life. This isn't a book about the glory of war and combat, but one about facing your enemies, some who are flesh and blood and some that are not: Your thoughts. Your doubts. Your boredom and your regrets.
