The green knots were only worn by battalion headquarter staff of the German regiments, with varying colours to indicate which battalion. The green and red indicates the 14th company of the 4th battalion, a training company attached to the staff. Solid green (ie without red), perhaps the rarest, was worn by regimental headquarter personnel.

This was carried on the bayonet frog of the Third Reich army and the colours denoted the company and the battalion within the regiment. This came recently from a tailor's shop in Germany. Worn by ordinary soldiers, especially on the walking out bayonets, in the early years of the war these knots were even worn on the combat bayonets in the field.
