But does that article support what you wrote, or what Munir Nassar wrote? 
I think it supports him more than you.  Your article says this, among 
other things:

    I've never heard of that word, and the German Panzer article has
    nothing about it. Google's search results make me believe it's just a
    joke by someone who wanted to invent a funny German word for tank.

    I agree; it seems absurdly complicated

    Pre WWII german tank AV7 is referred to as Sturmpanzerwagen, or
    Schwerer Kampfwagen in pages I have found. Can't discount the above
    long name though.

Other people report remembering learning the word as children, but so 
what?  What does that tell me except that the long word is probably some 
kind of joke played on children, sometimes by their German teachers?

When I was a kid, we used to say supercalifragilisticexpialidocious, but 
it was never a real word.  It's in Wikipedia, though:

    According to the 1964 Walt Disney film, it is defined as "something to
    say when you have nothing to say".
