When I was a kid, I read Comics almost daily. It was all DC comic books back then. Marvel hadn't hit the market yet. I had whole collections of Sgt. Rock, and Easy Company, and of course, Jeb Stuart and his haunted tank. You could learn a lot of History from snippets of conversations in those Comic Books.
A lot of my perspective about World War II, came from the characters in those books. And when I played with my little green Army men, I would often stage the battles from the comic books in my back yard.
I don't think there were any comic books about Vietnam or Korea...none that I know of anyway. And there is probably a Social Science PH.D for the reasons why. But I loved my Combat Comic Books.
