The imagery of war

A lot of the substance of the book brings the idea of male bonding to the front. It is a huge part of the war machine, if you think about it. That really is it. Why war exists is because mankind has worked out: if you take 15 men and put them together, that group, the number in a platoon, is the perfect number, the perfect group. It is like a hard-wired genetic code: if you bring a small group of men together and make them dependent on each other, they will kill for each other.
