I Was Victorious Because of the Science of Martial Arts

"When I look back at my military career, I think of all the things that I could do so much better now," he says. "If I would have had to write extreme ownership when I was a task unit commander, I wouldn't have been able to put together because I didn't have all that knowledge." He doesn't use quotes from other religions or books on military science in his new book. 'I understand a deeper principle of what I originally thought worked and I understand them more clearly'
