Final answer:
The Nazi troops used encoded communication in World War II through devices like the Enigma machine and substitution ciphers. The Allies were able to break the Enigma code, gaining valuable intelligence. Other methods like code words were also employed for added security.
Step-by-step explanation:
The Nazi troops used encoded communication in World War II by developing various methods to encrypt their messages and protect them from being intercepted by the enemy.
One of the most well-known encryption devices used by the Nazis was the Enigma machine.
This electromechanical device allowed them to encode their messages and transmit them through radio communication.
However, the Allies were able to break the Enigma code, thanks to the efforts of code breakers at Bletchley Park in Britain, led by Alan Turing.
They were able to decipher the encrypted messages, which provided vital intelligence to the Allies.
Additionally, the Nazis also used other methods of encoded communication, such as substitution ciphers and code words, to further secure their messages and maintain secrecy.
