Panzerschreck
Panzerschreck (lit. "tank fright", "tank's fright" or "tank's bane") 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 gun firing an anti-tank warhead. It was an enlarged copy of the American bazooka.
