The document discusses how technology and information warfare evolved during World War II and beyond. It notes that during WWII, the instruments of war were upgraded from motorization to mechanization. The degree of mechanization became a key indicator of a country's defense capabilities. The 1991 Gulf War further showed the importance of information on the battlefield. The U.S. and its allies' strong communication and reconnaissance capabilities led to their victory. This established that information technology and information warfare would be important trends in future military development, and that information would determine the outcome of wars, whether on the ground or in cyber space.
