Query: A little too much.

Where the book dealt with life in the battle zone, it was fascinating. There was less narration of this sort than I expected though, and most of the book dealt with Marcinko's rise through the Navy ranks and his dealings with the Navy bureaucracy. The main trouble I had with enjoying this book were the repeated, overbearing, egotistical remarks Marcinko makes chapter after chapter, page after page. I appreciate that to be a man in his shoes, one needs a huge ego to be successful or even survive, but the constant braggadocio really grated on my nerves. Marcinko is a rare breed and one deserving appreciation from every generation of American. His book though, is one part entertainment and one part irritation.
