Cowritten with John Weisman, the books are unique in tone and funny. Interviews with Marcinko suggest that, while very proud of his career, he tries to demystify himself and special operations, where others would try to build on the mystique and the whole James Bond aura of counterterrorism.
While I have read that SEAL 6 guys have referred to themselves as Jedi Knights, I'm certain somebody like Marcinko would not have tolerated that type of grandiosity. The commander of SEAL 6 to take over from Marcinko also wrote an autobiography and seemed very down to earth and low key. Of all the SEAL 6 autobiographies, Marcinko's is the most over the top.
The Warrior's Soul--Chuck Pfarrer, SEAL 6 officer during Achille Lauro hijack
One Perfect Op--Dennis Chalker, SEAL 6/RED CELL who stormed Grenada, a favorite of Marcinko
Combat Swimmer--Captain Robert Gormly, SEAL 6 commander after Marcinko (chapter 22 Audits and Investigations: The Marcinko Legacy)
Combative Fundamentals: An Unconventional Approach--Jeff Gonzales, SEAL 6, how to fight with a gun. Gonzales, like Chalker, does firearms training.
A few other books have been written by SEAL 6 members, but these are the ones I remember.
