"In the early 1930s he predicted, as Anthony Trythall wrote, “future armies would be surrounded by swarms of motorized guerillas, irregulars or regular troops making use of the multitude of civilian motorcars that would be available.” Fuller also mused that one day “a manless flying machine” would change the face of war. Early on he was intrigued by the development of radio, not only for communication but also as a way to control robot weapons. He also thought then-primitive rocket technology would one day lead to the development of superb anti-aircraft weapons. And as early as the 1920s, Fuller was a proponent of amphibious warfare. He envisioned a naval fleet “which belches forth war on every strand, which vomits forth armies as never did the horse of Troy.” Indeed, he foresaw future navies as being entirely submersible. On the negative side of the balance sheet, Fuller also championed the military use of poison gas, particularly when spread by airplanes. Even as late as 1961, with the publication of his book The Conduct of War, he blamed resistance to chemical warfare on “popular emotionalism.” If Fuller had a fatal flaw as a tactician, it was that he derided the importance of putting infantry “boots on the ground.” To him, combat was simply a matter of wool uniforms versus steel armor—and that seemed to him a no-brainer. Of course, Fuller had failed to consider the development of portable, shoulder-fired and helicopter-borne antitank weaponry."
