The 28/32 cm Nebelwerfer 41 (28/32 cm NbW 41) was a German multiple rocket launcher used in the Second World War. It served with units of the so called Nebeltruppen, the German equivalent of the U.S. Army's Chemical Corps. The Nebeltruppen had responsibility for poison gas and smoke weapons that were used instead to deliver high-explosives during the war. The name "Nebelwerfer" is best translated as "fog-thrower". It saw service from 1941–45 in all theaters except Norway and the Balkans.
