My grandfather was a soldier in the Pacific theater in WWII and he was always quick to point out that the Army had many more troops in theater, killed many more enemies, and suffered many more dead than the Marines did. The Army could have still won that theater without the Marines, albeit more slowly. The opposite is not true.
