That's probably in Technical Grappling. ;)

And yes, it would make sense for everyone to get it. It's not like prone levels the playing field; it's still worse to be the untrained fighter in that spot. You don't know how to leverage what you've got as well as the trained fighter.

You could easily extend the damage penalties listed under Postures, Hit Locations, and Techiques (page 98-99 of GURPS Martial Arts) to punches as well as kicks.
