"Cannon Rider!" from All-American Men of War #52 (DC, 1957) by Robert Kanigher and Joe Kubert
I see a war comic anthology, I immediately think of Joe Kubert. And that's what I want to see. Every time. Even if that means not showcasing one of the book's more memorable features, like Johnny Cloud, Gunner and Sarge, or Balloon Buster (who WAS drawn by Kubert on one occasion, but alas, no splashes).
