Feuerwerker

From the late Middle Ages until the Early modern period a Feuerwerker was a highly specialised artisan with detailed knowledge of the closely guarded secrets of making gunpowder.

In the modern German Bundeswehr, Feuerwerker is the collective designation to non-commissioned officers (OR5 to OR9) and officers of the military functional service (German: Offizier(e) militärfachlischer Dienst, OF1 and OF2) with several years of special training pertaining to construction, maintenance, and destruction of ammunition.

They were equal to the Junior and Senior Unteroffizier (Under Officer) in the land troops, respectively.

In the Austro-Hungarian Armed Forces Feuerwerker was equivalent to: The rank insignia was a gorget patch on the stand-up collar of the so-called Waffenrock (en: tunic), and consisted of three white stars on 13 mm ragged yellow silk galloon.

The gorget patch and the stand-up collar showed the particular Waffenfarbe (en: corps colour).
