Got a question that some of you, due to previous training and education might know, in regards to shot placement on the human body.
Now up front, I realize that bullets can do weird things when entering an object but generally speaking, how effective are shots placed at the lower abdomen height, think belly button center with two inches down or up? I realize that conventional thought is center mass more in the chest area, but how well does the lower trunk compare?
Hdtwice:
I've never served in law enforcement, only in the U.S. Army, so my training and experience is based on the military, rather than law enforcement. At the time of my training (Feb. 1975), the standard military issue weapon for most ground troops was the M-16/A-1 chambered in 5.56mm. These were equipped with iron sights only, and 20 round magazines were standard issue. We were taught to shoot to hit a man-sized/man shaped silhouette target out to 600 yards (sighting in was at 25 yards). I was lucky in that my Drill Sergeant saw that I had some ability with the M-16, and he would actually entertain some of my questions without resulting punishment. As an example, I was shocked to learn that at 600 yards, with a head/neck hold on the target, the round was expected to hit in the lower legs - "if you were lucky". None of the targets had any type of scoring rings on them. The idea was just to put bullet(s) on the target - anywhere on the target.
The U.S. Army in the mid-1970s was still using the "Quick kill" technique. This was a method of point shooting at man-sized targets at 20 meters and under. You were supposed to index the butt of the rifle under your chin, and not use your sights at all. In fact, they put masking tape over the front and rear sights during training to prevent their use. I was on my way to shooting "Expert", when I got tripped up by the "Quick kill" portion of our training. Try as I could, there was no way I could hit the target using "Quick kill". Finally, in exasperation, my Drill Sergeant asked how did I want to shoot the "Quick kill" targets? "With open sights and shouldering the piece like you're supposed to", was my response. Just to shut me up, he handed me a loaded magazine and told me to try - adding that I owed him 10 push-ups for every miss. I scored 20 out of 20 without any problems. When I asked the Drill Sergeant if I could continue to shoot the course using my method, instead of "Quick kill", he responded with "be my uh, guest".
Again, the objective was to put rounds on the target - anywhere on the target.
In real life, I've seen people who suffered fatal wounds, but in their remaining time, were still able to aggressively fight until they finally bled out. As others have mentioned, hits to the abdomen and lower extremities might eventually lead to a fatality. If you make hits to the abdomen you are, at best, looking at incapacitating your assailant until he/she succumbs due to shock and/or blood loss.
I've seen people who were excellent marksmen on the range. But introduce even a little bit of stress, and their skill level went south. If you are in a situation where you have to shoot someone to save or defend a human life, I think that putting your sights on the biggest part of them that is available and pulling the trigger is a good idea.
Good luck,
