Coming from a martial arts background, what I continue to find interesting is that this concern with OODA loops, milliseconds to react and application of violence is really only found among handgun or firearm users.
This deserves some thought. Though it's multifaceted, and the latter involves the use of firearms where a bullet is faster than a fist, not all MA are empty handed. Is it just over confidence?
Consequently, I've rethought all my SD concepts since I've begun carrying.
