Do you have one?
I don’t think I have ever even seen one unless it was an inert one in a museum.
I read a book titled “Ashes of Honor” written by an SS soldier serving in Russia. (It was one of the best books I have ever read btw). Anyway one of their favorite weapons was the Panzerfaust which appears to be the predecessor of the RPG. They all liked it, said it would take out a Russian tank with no trouble when they were close.
