IMO only, the Mozambique is a 3 shot skill [ 2 to the body, one to the head ] with a stop after two rounds to assess. I DO NOT LIKE nor ever liked/thought the Mozambique was something of a go to, it locks one into making two and whatever assessment time then making the head shot. I shoot 4-5 rds a second, after a second or so if they've haven't fallen I'll move to a failure to stop mode and go high to attempt a head shot.Isn't the Mozambique and the Failure Drill technically two different things, as well?
One has a pause, one does not?
During the week long national tactical invitational, they had Teddy tactical 3D's as threats in various entry scenarios. We were instructed that some Teddy's would not fall to body shots, we were then to make a head shot to drop Teddy. Only 125 were invited the year I attended [ around 1997 or so ]. Not one attendee I saw decided to just mozambique all Teddy's just in case. IOW, not one entry leo used it all week long.
Mozambique history https://www.shootingillustrated.com/articles/2017/5/18/the-mozambique-drill-a-history-and-how-to/
"Rousseau made a quick combat presentation with his pistol and planted two bullets in the area of his opponent's breastbone. In a fighter's worst nightmare, the soldier not only stayed on his feet, he managed to hang onto his rifle. Rousseau, having lowered his pistol to the ready position, assessed the situation and decided to deliver a third shot to the man's central nervous system. Aiming for the head, Rousseau either fired too soon or jerked the trigger, because his third shot hit his enemy in the throat. It did, however, sever the spinal column and neutralize the threat."
He asked Cooper if he could be allowed to call it the Failure Drill, suggesting the third shot was the solution for when the first two shots failed to stop the attacker. Mudgett said Cooper graciously told him to call it whatever he liked, the important thing was to teach it. At this point, the Mozambique/Failure Drill consisted of firing two shots at center mass, lowering the pistol to the ready position and assessing the need for the third shot.
Mudgett and Helms taught the failure drill to fellow officers and a number of other police departments. However, they felt officers might be wasting too much time in coming to the ready position after the two center-mass shots—time that could easily get them killed. They modified the drill so the shooter kept the handgun on target after the first two shots and transitioned for the head shot if the threat was still viable.
So what we affectionately know as the Mozambique drill is actually a modified Mozambique drill, but there's still that lag time of assessing after two shot, gun up or not, when they could still be putting lead COM. Hell, the first two shots may be a little errant and not take someone down, but a 3rd or 4th non errant shot may just do it. I don't like the idea of the gun barking, stopping to asses for any length of time, then resuming.
I'll plant 4-5 into COM and not hesitate to take the head shot IF by then they aren't succumbing to the shots. Looking at the odds on the streets, it's an extremely low percentage of running into turds wearing vests to begin with [ exceptions might be responding to bank robberies, armored car robberies and the like where the odds of a turd wearing a vest are slightly higher, but still very low odds. OMMV
Just like the speed rock as advanced and taught by Chuck Taylor in the 70's and 80's was thought at the time better than sliced bread, it's been discovered it's a very bad skill to use, putting one off balance. AND, it is no longer taught in law enforcement for a few reasons. Something thought to be great, turned into something not that good and discontinued in training.
