Here’s a TTP ( Tactic, Technique, and Procedure) that I’ll pass along.

The time honored ‘Mozambique Drill’ – 2 to the Chest/1 to the Head – as the ‘go to‘ failure drill has been obsolete in Close Quarters Combat training for quite a few years.
While it is still in the bag of tricks, the new discipline is – 2 the Chest, then go ‘downstairs’ to the pelvic region if those didn’t work.

In these days where actual body armor is more and more prevalent, and in the case of the murderer in Buffalo also adding in a helmet; going for a head shot that will ‘seal the deal’, requires more accuracy than smiting someone hip and thigh.
And while yes, blowing someone’s brains out of their skull will stop things and that right now, there’s lots of major body weight bearing bones, nerves and large blood vessels in a much larger and easier to hit area that extends from just below the navel down to the groin that will stop someone in their tracks too.
And just to reinforce the point, outside of full ‘Rattle Battle’ military armor systems, most body armor stops at that point, just below the navel.

I’m not the only one to take into consideration that it’s likely to be a lot more sporty out there as the spring and summer roll along to election season, so let’s keep up the level of situational awareness.
