Even as he becomes more hardhearted and used to killing, Perry never feels that he fully inhabits the role of soldier that his army service forces on him. He lacks the street smarts of someone like Peewee, who remains alert for traps at all times. In contrast, Perry seems to innately trust others, a quality that causes a lot of his suffering since his superiors so often betray him and other soldiers in Vietnam. As he waits for rescue, he reflects on how the war has changed him. It’s deprived him of his trust, and he doesn’t know what, if anything, has replaced it. Much of his trauma grows from this loss of identity and the questions it raises about himself, the war, and what it all means.
