You are falling into a classic fallacy of dismissing the information due to it's source. The fact is the war happened and these SEALs learned what they learned, working as one of the most effective units in the war. What you wrote could be true, while everything Jocko has to teach you can be true and useful too. I was extremely skeptical, but I read his book and there is value in what he teaches. It isn't all trite militaristic BS. Some of it is, of course, he has his world view, but that is easy enough to separate from what made them so good in a chaotic environment. I encourage anyone reading this to put aside their well earned bias against most military figures and dig a little deeper if the topic of leadership and personal responsibility are of interest.
