Who is Lefty Zepp from Goodbye, Darkness: A Memoir of the Pacific War and what is their importance? "Goodbye

Lefty Zepp is one of the original enlisted men in the author's intelligence section. Zepp, a Jew, was not known as such by his fellow soldiers. He is described as having slanted eyes, black curly hair, and high cheekbones. Zepp affects peculiar dress, carrying a swagger stick, binoculars, a fancy pistol, and handmade boondockers. The author feels these accoutrements made Zepp appear as an officer. Zepp was convinced that he would survive the war but didn't want to merely survive—he wanted to stand out as a brave man, and to this end he often took risks. Zepp is the first man under the author's control to be killed in action—he is shot in the groin and his bleeding, apparently dead body is handed back down the ranks. Zepp, a student at Harvard, was nineteen when killed. The author is disturbed by Zepp's death and conflates Zepp's groin wound to losing his virginity. Prior to military service, Zepp attended Harvard with the class of 1945 as a premed student.
