I don't want to get into a big discussion on PTSD, but I see many of the books, most of them great reads as a way for them to remember the friends they have lost and a constructive way of dealing with the baggage of the job.

Case in point right now I am reading a book called "The Outpost" it is more of an analysis of events in and around Kamdesh Village. It doesn't read the same because it is not a personal perspective so much as it is an accounting of the men who fought and died there from a different view. Essentially, the book makes you sincerely understand why so many people come back with demons. I've never been in war or held a friend as they bled out. This book puts you there, and gives you perspective.

All of that said, because I think these guys are vocal not because they are hounding for a spotlight, but because they miss their buddies, and they have an opportunity to immortalize them in the minds of the masses instead of having their only memorial be a name on a map of some shitty outpost that very few people have ever heard of.
