It's in reality their first leak outside of their founder.
There was Howard Wasdin's book from a year or two ago.
I acquired a copy of No Easy Day and am halfway through it. The opening "explanation" (calling it an Introduction would be a huge stretch as it is one big excuse) had me laughing or gritting my teeth depending upon the paragraph. His repeated use of "brotherhood" was particularly hilarious since he's been PNG'ed and knew he would be.
So far, a lot of it was fairly vanilla and nothing more than what you could read in Fearless, Chris Kyle's book, Horse Soldiers, etc.; generic war stories that honestly aren't much different than what you can read on this and other forums.
With that said, I've hit one or two spots already (I'm not into The Mission yet) that I couldn't believe he'd write about., even in generic terms.
As to the use of a pseudonym, he's a moron. I'll say it and be candid about it. In the "Introduction" he talks about protecting himself and his teammates (sorry, the "brotherhood") and justifies the use of a
nom de guerre. He then promptly lays out his life story with enough details you don't need to be Sherlock Holmes to figure out his real name so I think he's either a complete retard or did so for some follow-on whining or lawsuits once he was outed.
He justifies publishing the book based on the review of a "Special Operations Lawyer" (as mentioned earlier in this thread). Again, more ass-covering than concern for the "brotherhood."
It is also an airsofter's/ fan boy's wet dream with enough information about weapons and their effectiveness/ usage to spawn a number of know-it-all threads on the internet, airsoft sales, and other nonsense from the never going anywhere, never doing anything crowd.
The book is easy enough to read, but it doesn't feel polished...it feels rough, almost like the author merely transcribed a bunch of taped interviews or recollections.
Between this and Fearless you'll have a rough training outline of Green Platoon and the standards involved. Kudos for that guys...
Which brings me to my point and I'll shut up (until I finish the book): You could honestly start to pinpoint JSOC missions between this, Fearless, and reading the newspaper/ internet. Seriously. He's deliberately vague on some of the timelines (to protect the "brotherhood"), but then provides enough detail that you could start to flesh out the details or persons involved; to include CAG. Combined, the two books allow someone to start connecting the dots and I think that's probably the scariest part of all about it.
