First, let me counter a couple of criticisms by some of the other reviewers.
To the person who said the work was too self absorbed - I have no idea what you are thinking. The book is this mans journal - of course it is very personal. It is supposed to give us insight into his own inner conflicts. Personally I do not trust people for whom everything is so simple that they have no inner conflicts. That is fundamentalism and a distorted and shallow way to view the complexity of experience.
Second to the right wing nut who went off calling this guy a fruitloop for his work with the Marines etc. I have no idea what you are all about - or if you even read this book.
I will say that this book confirms for me the difference between a soldier and a warrior. A warrior is a pioneer of thought and last to pick up the sword. A soldier is essentially an automoton trained to take orders without question or thought. Both are necessary cogs in the US Military, despite their contradictory nature.
Green Berets in particular have missions that go beyond mindlessly fulfilling orders. As with many special operators they are required to think creatively, communicate with lead and inspire natives, and overcome obstacles. It's not just about what you see in Rambo movies.
This book is important for soldiers, and martial artists of all types. It gives us the sense that peace and conflict are like yin and yang- and cannot ever be totally separated. For hundreds of years the samurai (Japan's professional warriors) were expected to participate in writing poetry and flower arranging.
