War of telecommunication technology

In World War II, mobilisation orders via radio signals and telex allow warfare command over large distances of several thousands of kilometres.

In 1939, the Nazi regime starts World War II. Even before this date, civilian telegraph and telephone networks as well as wireless networks are extended in line with military requirements. The broadcasting industry of the Third Reich mainly manufactures military telecommunication technology. After various countries are attacked by German troops, the networks are extended all the way to the front-line areas through the use of special signal corps. Every fifth soldier of the German Armed Forces is from the signal corps.

In this way, the unprecedented war of conquest and extermination can be controlled directly from map tables in rearward bunker facilities. Entire armies are directed over distances of many thousands of kilometres via telex, submarines are directed on the high seas via radio signals. The Enigma, which converts plain text into code, is used to encrypt the radio communication. Directional radio tracking devices, on the other hand, such as the American Adcock direction finder, serve the purpose of tracking and intercepting enemy radio signals so that countermeasures can be taken.
