If you watched the old 1940's Superman cartoon, the art style is similar. Starting with the characters, they have prominent facial features and share the same animation. Look around, you should know Ketsudan is similar to the Eleventh Hour episode from Superman. They have the same WW2 theme. Lesson is reporters and journalists have been documenting history for a realistic or romanesque portrayal in both American and Japanese media. For sound, it is your typical Japanese WW2 officer barking orders like Adolf Hitler. Story includes attack on Pearl Harbor, following a historical storyline. Plenty of planes, wars, bombs, and Japanese raids. All about war! Noticethis is a strict history retelling so it is a powerful research tool.
