How do Private Goss' attitudes and expectations change after he has enlisted?

After enlisting, Private Goss's attitudes and expectations shift significantly as he faces the harsh realities of military life. Initially, he may have romanticized the idea of serving, viewing it as an adventure or a means of proving his bravery. However, as he experiences the rigors of training and the pressures of combat, his idealism is replaced by a more sobering understanding of the sacrifices and challenges that come with being a soldier. This transformation often leads to a more pragmatic and sometimes cynical view of his role and the war itself.
