After reading Captain Couch's book, you will deeply appreciate the SEALs and all special operations forces in general.
You will also understand why most people consider SEAL training to be the most grueling in the world.
While the books provides great detail on Phases 1, 2 (including Hell Week), and 3, the chapters on Phase 4 and "Beyond the Basics" seemed to have been written in a weekend. As I got to this part in the book, I felt let-down based on the excellent coverage in the first part of the book. The material repeats itself in several places, especially towards the end. However, some topics (e.g., IAD) should have been expanded upon.
It's easy to stand on the sidelines and critique while the man in the arena writes the book. However, I believe that the book lacked a consistent level of detail. So, I am giving it four stars.
I'd also like to add that the 'lack of detail' regarding Phases 2 and 3 is because some of the things in Dive Phase are classified, and most things in Third Phase are classified. Details about IADs should not be expanded upon due to a potential violation of OPSEC. The security and safety of our boys on the ground should be of primary concern, with the public's entertainment somewhere far behind.
