Panzerschreck (lit. "armor fright" or "tank fright") was the popular name for the Raketenpanzerbüchse (abbreviated to RPzB), an 88 mm calibre reusable anti-tank rocket launcher developed by Nazi Germany in World War II. Another popular nickname was Ofenrohr ("stove pipe").
The Panzerschreck was designed as a lightweight infantry anti-tank weapon. The weapon was shoulder-launched and fired a fin-stabilized rocket with a shaped charge warhead. It was made in smaller numbers than the Panzerfaust, which was a disposable recoilless rifle firing an anti-tank warhead.
