Bizarre west-German disposable single shot incendiary grenade launcher pistol thing.
Intended for use against bunkers and buildings, it lobs a grenade packed with red phosphorous.
Supposedly early versions of these were supplied to US special forces in Vietnam, they were supplied without English manuals which allegedly lead to an incident where a bunch of MACV-SOG guys nearly blew themselves up trying to figure out how to operate these things.
