A German-language training manual for signallers, first published in 1941. The full title translates as "The Field Telephone: A Handbook for the Signal Troops and Unit Signallers, with the MG 34 in the Light Machine Gun Role, the MP 38 and MP 40, and Motor Transport Training."

The pairing of subjects looks odd to modern eyes but reflects how the Wehrmacht trained. A signaller was expected to be an infantryman first, so alongside the field telephone the book covers the handling of the MG 34 as a light machine gun, the MP 38 and MP 40 machine pistols, and the driving and maintenance of motor transport. Signals units were among the most heavily motorised in the army, and a man might spend his morning on a telephone exchange and his afternoon on a vehicle or a gun.

Issued in the second year of the war, when the German army was at the height of its success and expanding fast, it is a useful source for anyone studying German signals equipment and organisation, the small arms of the period, or the way the Wehrmacht prepared its specialists for the front.
