I'm suprised that no one has attempted to identify the anti-tank weapon that the redneck is holding in the picture... it appears to be a 20mm Lathi anti-tank rifle. Used in Norway (mebee Sweden, think norway though) during a war with Russia. They lacked an effective armor force to face the Russians with, so they improvised and came up with a very nice 20mm rifle that could be served/transported by a crew of three (2 if they were in dire straights).
It usually comes with a bipod that had "skis" on its feet so that it could be dragged across the snow rather than being carried.
As one can guess from the picture, It puts the American .50BMG round to shame for sheer destructive power.
When sold on the open market in the US those rifles usually go around 12000usd. Getting ammo is the problem, anything over 1/2inch diameter is classified as a "destructive device" and federally regulated. Yeesh.... why would that be considered a destructive device?
edit: just looked a the picture again, The "skis" are clearly visible on the rifle, they are in the center area of the weapon. And damn I want one, Barret 82A1 up for trade +cash if anyone has a line on a Lathi =)
