These shoulder straps represent an authentic example of Wehrmacht uniform insignia from World War II. This pair of shoulder straps for a Non-Commissioned Officer (NCO) of the Signal Corps of the Army (Heer) is manufactured in the characteristic dark green felt execution and was designed to be worn on the field tunic (Feldbluse).

The Nachrichtentruppe (Signal Corps) formed an essential component of the Wehrmacht and was responsible for all military communications, including telephone, telegraph, radio, and messenger connections. The importance of this branch cannot be overstated, as modern warfare became increasingly dependent on rapid and reliable communication. The branch color (Waffenfarbe) of the Signal Corps was lemon yellow (Zitronengelb), which was visible on shoulder straps as backing or piping.

The Army Service Regulation (Heeresdienstvorschrift, H.Dv.) meticulously regulated Wehrmacht uniforms. Shoulder straps served a dual purpose: they indicated both the wearer's rank and unit affiliation. For Non-Commissioned Officers, shoulder straps featured characteristic braiding (Tresse) that distinguished them from the plain shoulder straps of enlisted men.

The dark green felt execution was typical for field uniform items and corresponded to the field grey (feldgrau) basic color of Wehrmacht uniforms. Unlike shoulder straps for walking-out uniforms, which were often more elaborately designed, field tunic shoulder straps were conceived to be functional and robust. The felt used was durable and weather-resistant—important qualities for field service.

The NCO corps formed the backbone of the Wehrmacht. These ranks included Unteroffizier (corporal), Unterfeldwebel (junior sergeant), and Feldwebel (sergeant), with shoulder straps indicating the exact rank through different numbers and arrangements of braiding. NCOs without sword knot (Portepee) wore a single aluminum or silver-colored braid at the upper edge of the shoulder strap.

The organizational structure of the Signal Corps was complex and encompassed various specializations: telephone operations, radio troops, telegraphy, and signals intelligence. NCOs of the Signal Corps required extensive technical training and were often responsible for the maintenance and operation of sensitive communications equipment.

The manufacture of shoulder straps followed standardized specifications, yet there were variations depending on manufacturer and production period. During the course of the war, material shortages and changed production conditions led to simplifications in manufacturing. The present shoulder straps correspond to the regular execution for field use.

Today, such original pieces represent important historical documents that provide insight into the military organization, rank structure, and material culture of the Third Reich. They are significant objects of study for military historians and serve the factual documentation of this epoch of German history.
