Back in the day, DC published a variety of books including War comics. “Weird War Comics”, “The Unknown Soldier”, and “Sgt. Rock” ‘were some of the big names. Like Western and Romance comics, War comics fell out of the readers favor. So for the New 52 DC dusted off a property called “G.I. Combat”.
“G.I. Combat” was an anthology series originally published by Quality Comics in the 1950s before being bought out by DC. The title focused on Cold War themed stories before switching to a World War II setting. DC kept the title going before canceling it in the 1980s.
