But on the other hand Sokolov owed his life—his survival in Afghanistan, in Chechnya—to his ability to see things through the eyes of the adversary, and in this case that meant trying to put himself in Ivanov’s shoes. This reversal of perspective was not always easy. One frequently had to work at it for some days, observing the other, gathering data, even conducting little experiments to see how the other reacted to things. His men in Chechnya had thought that he, Sokolov, was crazy because he had sometimes taken actions that made no evident tactical sense, solely as a way of proving or disproving a hypothesis as to what the Chechens were thinking, what they wanted, what they were most afraid of.
