ABSTRACT
World War II saw the emergence of two areas of technology that, together with aeronautics and submarines, were to revolutionize the conduct of warfare in the twentieth century: nuclear weapons and the evolution of the wireless of the 1920s into modern electronics. From the time military forces came into being they have continually improved their weapons and tactics. But only rarely has the appearance of new kinds of weapons and tactics brought about revolutionary change in the course of warfare. The Greek phalanx, developed further by Philip of Macedon and used by Alexander the Great and the Roman legions, was one such change. World War II was a period of sudden change in the military arts and sciences. Operation of land forces by the end of the war was characterized by the massive use of armor and tactical aircraft in land battles.
