In this section, we see a very general account of Berlin’s relationships with Doc, Sidney Martin, and the other soldiers. O’Brien will return to describing these relationships again and again, each time in more specific detail. The structure of the novel isn’t best described as “moving forward”—rather, O’Brien goes into more and more depth about the same incident. This is a clever strategy for a book about Vietnam, because it places our focus on memory and introspection. The novel isn’t just a story about going after Cacciato—it’s about how one soldier, Berlin, makes sense
of his experiences.
