The Signal Corps or Nachrichtentruppe, in the sense of signal troops, was an arm of service in the army of the German Wehrmacht and Waffen SS, whose role was to establish and operate military communications, especially using telephone and radio networks.

By order of the Oberkommando der Wehrmacht dated 14 Oct 1942, it was part of the combat arms of the German Wehrmacht and Waffen SS until 1945.
The colour allocated by the Wehrmacht and Waffen SS in 1935 to their signal corps was lemon yellow. By contrast, the corps colour of the air force signal troops of the Luftwaffe was brown.
Background: First World War and Reichswehr
The precursor of the German Signal Corps was the Telegraph Corps formed in 1899 as a separate arm of service. Telegraph battalions, fortress and army signal units were not combined into the Signal Corps, the Nachrichtentruppe, until 1917, during the First World War. In addition to radio and telephone communications, the newly developed teleprinters, carrier pigeons and heliographs were used for messaging. During the First World War, radio telegraphy took on increasing importance. For example, in 1915 teleprinters were first used by the air force, for artillery observation. In 1916, the first signallmen equipped with mobile radios were operating on the front line.
In the Reichswehr from 1921 each division had a communications unit with two companies. As well as radio and telephone communications, signal pigeons were also used for the transmission of information. From 1930, Enigma cypher machines were used for the first time to automatically encrypt secret information.
Creation
During the rearming of the Wehrmacht the first top secret rearmament measures were carried out in spring 1933. These measures included the formation of new units and the establishment of a second signal company in existing units, the recruiting of officer cadets resulting in an eightfold increase over that on 1 April 1933, the reinforcing of the officer and NCO cadre by former signals soldiers, and their training through various courses. From 1934, from the old signal units the required cadre of officers and soldiers was drawn for the establishment of new formations, the divisions of the Wehrmacht each receiving a signal unit. Meanwhile, the Signal Corps steadily expanded its field of expertise; they now had light, medium and heavy telephone troops, telephone exchange and telephone operating troops, telegraph construction troops, light and heavy radio troops, miniature radio troops, two-way radio troops, radio surveillance troops, patrol radio troops, cypher and evaluation troops and battery charging troops.
From 1935, the training of the Signal Corps was carried out at the Army and Air Force Signal School (Heeres- und Luftnachrichtenschule) and, from 1936, the Army Signal School (Heeresnachrichtenschule) in Halle-Dölau. Two central bunker systems were built as communication centres in Zossen and in Ohrdruf.
From a special-to-arm perspective the Corps was led by the Inspector of the Signal Corps (Inspekteur der Nachrichtentruppen) at the Oberkommando des Heeres, the individual formations and units were subordinated to their respective commanders in the field army.
Organisation and strength
At the start of the war the Signal Corps had:
In addition, at unit level there were the signal troops of the combat forces like, for example, those in the artillery or chemical warfare units. They did not belong to the Corps of Signals, but were integrated into the formations and units and were subordinated to the commanders of their respective companies, batteries and squadrons.
The propaganda forces were also part of the Corps of Signals until 1942, but then became an independent arm of service.
As more large formations were created during the war, numerous new and reserve units were established including independent signal companies or special units, among them the wire construction companies, decimetre band (i.e. UHF) radio relay companies, carrier frequency companies, telephone exchange companies and telephone maintenance companies.
Deployment during the Second World War
The Inspector and General of Signals Erich Fellgiebel, who was executed in 1944 for his part in the 20 July plot against Hitler, was credited with saying: "The Signal Corps have a tough time. You can't smell them, they don't make a noise, most people don't notice that they exist at all unless the communications stop working."
Postwar development
Both the lemon yellow corps colour and the name Nachrichtentruppe were retained by East Germany's army, the NVA, until 1990.
On the other hand, the German Bundeswehr changed the name to Fernmeldetruppe, but kept lemon yellow as the corps colour.
