If you have not taken the time to thumb through FM20-22 then you're missing out. While a little antiquated given advancements in modern recovery gear (their use of chains compared to modern synthetic gear), and somewhat overkill for the recreationalist (unless you're adventure vehicle of choice is a tank) there are some really sound things in here theory wise.

One of my go-to for my own teaching is the breakdown of R.E.C.O.V.E.R.Y:
  • RECONNOITER AREA
  • ESTIMATE SITUATION
  • CALCULATE RATIO
  • OBTAIN RESISTANCE
  • VERIFY SOLUTION
  • ERECT RIGGING
  • RECHECK RIGGING
  • YOU ARE READY
It's a great way to break down a complex process into an easy to follow systematic process.

Beyond that, there are all kinds of gems from rigging math, improvised ground anchors, rigging math, improvised traction aids, rigging math, oh, and lots of rigging math.

Oh, and the hand-drawn artwork is stellar! My personal favorite has to be page 90.

For those unlucky enough to not find a paper copy, here's a link to a PDF copy: https://www.bits.de/NRANEU/others/amd-us-archive/Fm20-22(62).pdf

I've actually printed out a few of the charts, put them through a laminater, and then tossed them in my rigging bag.
