I suggest Zombietactics write a strong letter of disapproval to the Army explaining that they labor under a delusion, are wrong, and only he can send them a list of technicians who will explain it to them.
Well, this thread is not
about me or what
I believe. The Army will do whatever it does. Whatever they do does not alter the laws of physics, which make impossible any notion such as "knockdown power".
The Army (and Marines, for that matter) have all sorts of excellent resources at their disposal, but that does not mean that they always make decisions based upon what the "the best thing". Budgets matter, and so do lines of supply. Even if there were a demonstrable difference (there isn't) between battlefield performance of .45ACP "hardball" and the 9mm NATO load, I'd imagine they'd stick with 9 owing to
weight and
size, which has bearing on all sorts of other things.
I'll note that you jumped to several conclusions not (pun warning) militated by the text you quoted. I can explain, if you have any interest.
I can post a LOT of references from qualified sources, but it seems silly to do so if they will be evaluated based upon
who they are, rather than an
understanding of the data presented.
So far as the "who" is concerned, I've already presented Larry Vickers (Delta Force), Kyle Lamb (Army SF) and Kyle DeFoor (SEAL Team 6) ... and wellas MARSOC trainer Steve Reichert, regarding problems with the 1911 design. That's simply a case regarding reliability of the gun, which can readily be assessed by direct observation.
The subject of wounding effects and terminal ballistics cannot be correctly assessed in such a manner, owing to the nature of the environment. It's a well-know fact that eye-witness testimony is regularly falsified by video evidence. People simply do not recall what they have seen, or what has happened, even in simple convenience store robberies. Consider the far more chaotic environment of combat in war ... and don't deceive yourself that anyone knows with any clarity what any particular round is doing. We've yet to see a single piece of video footage where a 45 (or 40 or 9) "knocks a man down" or "spins him around" as some have suggested in these kinds of discussions over the years. This isn't surprising, as physics would tell us the same thing.
The evidence of medical examiners, forensic pathologists and trauma surgeons indicates that there is no difference between the wounds created by handguns in the 9/40/45 range. That's
science ... decades of data. I'm not sure what more needs to be said than that.
Even so, I'll end with this, and there is a lot more where this came from:
"Kinetic energy does not wound. Temporary cavity does not wound. The much discussed “shock” of bullet impact is a fable and “knock down” power is a myth."
