Weren't there some issues with the bazooka/rocket launcher?
Well, yes... because the one in the film is a fictional weapon created by the prop department. It's basically an amalgam of a German panzerfaust and a later Russian RPG and never existed. I've been working on creating it custom, but haven't finished yet. I guess I'd better get off my duff soon and do it. I have all the pieces I need to custom-build one.
