In 1966, just as the American military buildup in Vietnam was going into overdrive, a working-class 22-year-old from Chicago was drafted into the army. Larry Heinemann served one year of combat duty with the 25th Infantry Division, most of it in the vicinity of Cu Chi. It was the most horrific and consequential year of his life, and it became the raw material for his two classic war novels, Close Quarters and Paco's Story.
