Where can I buy one of the pick-up trucks that the military and contractors use in Iraq and Afghanistan?

I'm currently stationed in Iraq, and as we draw down the number of troops and equipment, I can't help but wonder where all this equipment is going? I know about a third of it is going to Afghanistan, and about a third is getting turned over to the Iraqi government, but what about the pick-up trucks. There are 2006-2009 F-150s, Rams, and Suburbans everywhere. It wouldn't surprise me if we are giving them all to the Iraqis, but does anyone know of any way a Soldier can purchase one of these trucks? I know they are beat up, but a little work and one would make the perfect utility truck. I've tried online auctions, but most of the trucks are just ancient 5 tons.
