There has been so much written about war because a writer looks for drama and the imminence of death makes war dramatic. Men are more interesting. They live most of their lives at half-speed, using only a portion of their brains, their muscles or their emotions.
War is the ultimate competition.
They use everything they have. It brings out virtues and shortcomings in people that they never saw in themselves before. They do things they didn't know they could do because those actions were not called for in peacetime. Very few men in an Army do all the fighting and dying. I am not a glorifier of war nor even of the men who fight wars.
