Portable winch, plywood, boat anchor to set the winch in the ground, shovels…
…as many guys as you can get to dig, blocks of 4x4 wood to Jack up from, then winch out of the rut.
I’ve gotten stuck and helped others get out of the mudflats / salt flats.
Takes some work, but can be done. Better. Than laying $5000+ to have a snowcat pull you out.
