World War II
During World War II, the Pacific and European Theaters were similar in that many of the same weapons were utilized and most of the same nations were involved, although Japan was the primary Axis Power in the Pacific, with Germany and Italy as the Axis Powers in Europe. Differences between the theaters are many, with perhaps the most important being the land-based focus in Europe and the sea/air focus in the Pacific.
