Let’s be factual about the Marines’ activities in the fighting in the Pacific in WWII. Those Marines were a very vital part of our winning the war there with their many self sufficient battles. However, I tend to believe the Marines would have it that the many more Army divisions involved were just window dressing as is typical Marine gung-ho stuff. I had an older step brother who was a career Marine going back to the first China-Japan conflicts. When he visited us before WWII he was always spit-and-polish. He did survive WWII. I stand by the sacrifices of all ,the Navy, Marines and Army(including then Air Force) as being of ( The Finest Generation).
The Army did most of the fighting in the Pacific, in fact Army losses in the Pacific are almost exactly the same as the total WWII loses for the Navy and Marines combined, and the global WWII Navy losses were about double of the Marines.
The Army was also using their Indian “Windtalkers” as radio men, in the Pacific, North Africa, and Europe, the Army had invented the concept in WWI.
The media has created a distorted view of the Pacific war.
