how/where would you go about practicing this safely and professionally outside of something like a pmc or a military
I've never heard something like this before
Books, Videos, Demonstrations, actual practice, etc
My Father has taught me a few things as he is ex-army but me and my cousin we sometimes do stuff like HEMA ( Historical European Martial Arts ) but we primarily focus on self defense / combat use of a knife. This also helps as I plan to join the military.
You can do this stuff in a Gym with floor padding and protective gear on like a face mask, cup, etc.
