How To Get On The Highway on Tehran Highway in Battlefield 3 (and MAV / floating soldier glitch)

This has been patched and no longer works. How to get to an amazing sniping spot on the Tehran Highway map in Battlefield 3. Yes, I know you can do it on your own now. This video was made before the patch that gave you the ability to do it on your own. I, personally, never use this, but I thought some of you might like to know about it. :)
