This mockup looks like it'd be right at home in Crysis (or many other sci-fi FPSes).

It's a nice design, though it clearly looks like something designed by a graphic artist.
You know, in the West (and in Russia, as a matter of fact), such designs are common at the "early concept" stage, but the artists usually get a modeling program to make spiffy renders of their ideas instead. Poland being what it is, they had to do with gluing plywood onto a CV-90.
It would probably fool more people than the one Hamas made, at least. And yes, even if you did forget to paint over the great big "CONCEPT" sign on the side.
