Marcinko explains the there will be more Rogue Warrior books to look forward to, as well as a movie on the original autobiography. There was also a CD-ROM came in 2004 and some collector figurines, both of which are no longer being distributed.
I picked this book up ten years ago shortly after I joined the military. I read it once every other year or so, along with his other Rogue Warrior books. Eye opening and truthfully gritty recollections of the birth of U.S. Special Operations...and the political games that the nerds in command can play.
