Definitely get both, if you're interested in war comics. Especially Blazing Combat. It's basically a continuation of the EC war comics, just in b&w but with many of the same artists (Toth, Severin, Crandall, Wood, Williamson) and even more grown up (the series was published over 10 years after EC had disappeared). There's also a hardcover version (which is the same size and content as the softcover one, though).
