I know quite a few people who rave about this series, but this is the only issue I've ever owned. I am pretty darned happy with it, too. Why is it a hidden gem? Well, let's start with the lovely John Romita cover. It's may be odd to see three key Avengers bursting through a map of Southeast Asia, but it sure is cool. This issue comes across as a quasi-What If? as the soldiers imagine what the war would be like if superheroes had been involved. It is all quite light hearted, or as light hearted as a book about Vietnam can get. What I really like however, is how the same soldiers absolutely skewer the John Wayne-starring Green Berets. They take that film to task and some of the panels are recreations of scenes from the movie. All in all, this is a bit of an oddity and one I think you'd be happy to have in your collection.
