You don't want to be the driver of the HMMWV shown. The one with the mine roller attachment.
There's a third set of wheels that cover the center of the mine roller attachment. So, it's some poor guy's job to just drive along until the wheels set off a mine and scare the bejeezus out of him (or her).
Those black things behind the wheels, that look like they ought to provide blast protection? They're just rubber mud flaps.
