„Unlike other comic book creators who were given either stateside or way-behind-lines assignments, and perhaps because Kirby understood Yiddish, the Jewish German dialect spoken by his family, he was sent as a scout behind enemy lines to draw maps. He endured and survived many harrowing violent experiences during his service, almost losing his feet to trench foot. He had no time for fascists or racists.“
— Jack Kirby
