I have to agree these guys don't do this for a living or may have not ever recovered a vehicle before. It would have been 100 times easier to winch it up on the back of a flat bed trailer designed for a bull dozer or the trailer they brought the shovel out to the beach with. I guess it wasn't still there for them to use. The two tracked vehicles they finally towed it with looked military I think I would have asked to borrow a tank recovery vehicle. they would have been out of there in a day.
Just my two pennies.
