^^^I don think he meant pulling out by hand. lol!^^
He is talking about using the unstuck rig to pull out stuck rig. Works great. Everybody should carry a tow strap, and that should be good enough. Snatch block and anchor is a bit over kill. I have 60k pound 4" strap, and I think you would be hard pressed to break that. Most important is that all rigs you are wheeling with have solid front and rear tow points and you'll be fine.
Let me add you should always wheel with at least 1 other rig.
