“The Japanese fought to win - it was a savage, brutal, inhumane, exhausting and dirty business. Our commanders knew that if we were to win and survive, we must be trained realistically for it whether we liked it or not. In the post-war years, the U.S. Marine Corps came in for a great deal of undeserved criticism in my opinion, from well-meaning persons who did not comprehend the magnitude of stress and horror that combat can be. The technology that developed the rifle barrel, the machine gun and high explosive shells has turned war into prolonged, subhuman slaughter. Men must be trained realistically if they are to survive it without breaking, mentally and physically.”
