Air Cushion vs IED

Found this at the Washington Times (scroll to bottom):

Some outside experts say the way to outfox the enemy is to develop air-cushioned vehicles that can travel off-road. The vehicles could take one of thousands of different routes from point A to point B with the entire Iraqi desert as their highway. With so many travel route options, it would make IEDs useless, the experts tell us. They further say that developing a new family of air-cushioned vehicles would be a good way to transform the military for future battles against terrorists. What better way for special operations troops to get around, they ask.
