Query: An awesome adventure and scifi Nam experience

This book is cool. Get a look into how much a country and a person can change during war. The earth Mandala returns to after each combat tour mirrors what it must have been like to return to the U.S. from Nam after so much social change in the 60s. The bureaucratic shenanigans do not change in the future, and in the end, nobody thanks the soldier for defending them from nothing. The joke's on you. I was somewhat disappointed in the ending, but on the other hand, I was impressed with the ending before the ending. A fun, recommended read.
