He was injured for much of his naval career which is why he didn't rack up a multitude of deployments, yet he still did deploy, saw combat and performed well. He did not bitch out, and purposely bail out of deployments like you are implying. I think you'd have to be a pretty bad judge of character to not have any issue with what Dan Crenshaw did. He got flamed by people when this stuff happened and for good reason. Imagine thinking it's normal for someone to bad mouth another guy who's never said anything bad about you or anybody else and then shamelessly also asking that guy to help you on a book you want to sell. That's some of the most two faced scummy shit a person could do.
