How does Richie's perspective of the war change?

Perry is a contemplative soldier, often analyzing his decision to go into war in the first place and questioning the moral reasoning behind the American presence in Vietnam. However, Perry's time at war changes him. He forms a tight bond with the other members of his squad, especially Peewee, and earns two Purple Hearts for being twice injured in the line of duty. Most importantly, Perry realizes the importance of human connection and family. Myers loosely based all of the characters in Fallen Angels on his own experience as a young soldier in Vietnam.
