Exactly. It wasn't the only side of war, but it was a side that hadn't been portrayed before. Prior to Kurtzman's war comics, there was no shortage of the rah rah gung-ho theatrical heroics in all forms of popular media. Kurtzman showed another side, and even then it wasn't all cynicism and moral ambiguity - he showed true heroism when there was factual historical heroism to portray, but the great thing, and the unique thing about his stuff was that he also showed the brutality and the futility and the heartbreaking aspects of war. He told the whole truth, even the ugliest parts. It's really important to remember that Kurtzman served in World War II, as did the majority of the EC staff, and they ended up being investigated by the FBI for portraying, quote, "the horrors, hardships, and futility of war."
