Kriegsmarine decals differ from Heer decals primarily by color and to a lesser degree by design. KM decals stand out from the silver color Heer decals by having a gold color, which may range from deep gold to a paler gold.
Otherwise the appearance or design is nearly identical to Heer.
One detail that is important to recognize on KM decals is the raised border line around the eagle and swastika due to its 2-piece construction. The
eagle/swastika was produced on a sheet separate from the underlying black shield, unlike Heer decals that were produced entirely on one sheet.
