Decal shows insignia placed on the both sides of the helmet used by HEER troops.
Each organization that used helmets had its own distinctive insignia. This was true of all military, political and civil organizations in general and these insignia can therefore be found on all the different styles and models of helmets described thus far. Decals are designs or images made to be transferred from specially treated paper to a hard surface.
They are attached by means of water soluble adhesive, which permits them to adhere securely to the painted shell, whether smooth paint or textured paint was used. The decal actually conforms itself to the surface to which it is applied and is generally impervious to water and other elements of nature, once it is situated.
The insignia is centered directly beneath the vents on the both sides of the helmet.
