Looking for WWII-Related Anime

[Vulkurt]

Hello, all. I have really been enjoying Zipang but I would like to see more anime about WWII. I already have Barefoot Gen and Grave of the Fireflies, and unfortunately I cannot find The Cockpit. Gen and Fireflies are more about aftermath rather than the actual combat. I'm looking for anything along the lines of anime that focuses on WWII. Any suggestions would be welcomed. Thank you.
