On a safety note, be careful where you hook up to. The British Army only allow the use of Kinetic (snatch) ropes on armoured vehicles, due to the danger when things go wrong. I once saw the tow hitch let go on a bottomed out Land Rover, it went through the back window and split the roof of the Range Rover that was snatching it. By some miracle no one was hurt. The effect is a large lump of metal fired by an even larger slingshot
