World War II was a radical war in many ways, but one of the most significant novelties was that of increased use of the radio. Communicating by means of wireless radio became imperative to military forces and their ability to in contact. The need to stay in contact and be able to receive directions was vital to the military. However, there was a significant problem with the use of these radio messages. This problem was that the messages could easily be intercepted and thus important information would often fall into the wrong hands. This important information could include such intelligence as secret plans and instructions. To combat the interception of information by enemies, information was often communicated through using secret codes. Each of the major world powers had their own code machines that would turn any normal text into code. They each had machines that could decrypt their adversaries’ codes also. The ability to decrypt enemy codes became an extremely important and momentous development in World War II. Cryptology was more significant during World War II than during any other war prior to it or after. Developments in radio caused large amounts of communications to be conveyed across the airwaves, but this also meant that these communications could be intercepted by others that were not supposed to receive them. Radios had been around for a while. However, they were not applicable to land campaigns during World War I because they were such bulky machines. Yet, that had changed by the time World War II came around. The Germans were especially exposed because their policy of Blitzkrieg relied on directions and orders being sent.
