I would add some thoughts to the "Avoid" part
Sometimes it's easier to make them avoid you instead. Attackers are like hunters they're looking for easy prey, a seemingly weak one. By showing strength through body language, we can easily make them pass by and keep searching for an easier victim. Plus, martial arts like Karaté and kung-fu... Can help with body language for the "Avoid" step as well as with the "Engage" part.
