G.I. Combat #167 (December 1973) gives us a fine example of this. The back-up story is "Just Another Mission," written by Steve Mitchell and drawn by Ken Barr.
It's about a British Long Range Desert Group team, given the job of travelling behind enemy lines just before a big push and capturing an airfield that will be needed for flying in supplies. Lt. Steed, the unit's commander, is assured that resistance will be light and that there is no enemy armor present.
The story immediately earns points by featuring British soldiers, though actually DC's war books were very good overall about acknowledging the accomplishments of our Allies as well American soldiers. It earns more points when we find out the airfield is held by Italians. In World War 2 fiction, Rommel's Afrika Korps get so much attention, we forgot that Mussolini's soldiers were there first.
Mitchell's concise script moves the story along quickly and Barr's art really shines when the attack on the base commences. We're able to follow the action, but Barr also infuses it with a sense of chaos and real danger. When the Italians turn out to have a tank--despite what Steed had been told--the British end up taking quite a few casualties before they take the airfield.
The next day, Steed learns that it had all been for nothing. The British attack had been called off. Steed is told he might get a medal and that his lost men and equipment will be replaced, but that doesn't really help all those dead men, does it?
