Waffenfarbe

)[1] The Bundeswehr uses a Waffenfarben color scheme to indicate troop types; they appear on the collar patch and as piping around the shoulder boards or straps showing a soldier's rank.

The Waffenfarben used in shoulder strap piping of the M1907/10 Feldrock was instead related to army corps, with exceptions to certain regiments due to seniority or distinctions.

East German (DDR) Nationale Volksarmee uniforms initially wore the Waffenfarben as worn by the Wehrmacht.

However, air/air defense forces, paratroopers, and generals as well as the navy continued to wear their specially designed Waffenfarbe patches.

Today, Waffenfarbe schemes are also used in Austria, Finland, France, Hungary, Italy, Japan, Poland, Romania, Somalia and Switzerland.

The blue border around the shoulder strap of this uniform indicates that its wearer is assigned to a logistics unit. Note that the epaulettes on the camouflage uniform ( Bundeswehr ) at the back do not have blue trim.
