Panzerfaust

The first disposable, anti-tank weapon the Panzerfaust was the German answer to the American bazooka rocket launcher in WWII.  Deadly against all forms of allied armor during the span of the war, the Panzerfaust was somewhat handicapped by it's short effective range.  It's capture and reverse-engineering by Soviet forces during the war led directly to the production of the RPG-7.  In video game environments, the panzerfaust typically pops up in WWII-themed games, either as a rocket launcher equivalent in FPS games, or as a way to lend Axis soldiers some anti-armor punch in strategy games.
