Charlton's Special War Series lasted a mere four issues. Beginning in the summer of 1965, the four issues of the series came out monthly, each offering up a different title and blend of war action. "D-Day", "Attack", "War and Attack" were the titles. All of these became series for Charlton. But it's the fourth and last issue which is of course special interest here because it features the debut of Frank McLaughlin's Judomaster.
Special War Series seems to have been a showcase-style book for potential war comics. If so, it's the only one I'm familiar with. Have a safe and careful Veteran's Day. They've made it possible.
