Just an update to a comment I made in the AMA about the military's new hotness as of two months ago, in response to this question:
https://www.themotte.org/post/296/im-a-gun-guy-ama
what's your take on the NGSW? I'd be interested in knowing your thoughts on the LMG and service rifle aspects of it, as well as your thoughts on the entire program.
To which I replied:
All these "new infantry arms" are a boondoggle for arms manufacturers. Billions of dollars to not replace the M16, or to marginally improve some esoteric aspect of the platform. The M5 is not going to be the standard infantry arm of the US military.
Today's update: https://www.armytimes.com/opinion/commentary/2023/02/28/the-not-really-next-generation-weapons-program/
Pull quotes:
the Next Generation Squad Weapons program is imploding before Army’s very eyes. The program is on mechanical life support, with its progenitors at the Joint Chiefs obstinately now ramming the program through despite spectacularly failing multiple civilian-sector peer reviews almost immediately upon commercial release.
Starting from a highly dubious intellectual, strategic and tactical baseline, the NGSW program is now failing mechanically and ballistically at once. Army came out hard with the program’s aims and expectations, unreasonably so, practically declaring a War on Physics from the outset. Unfortunately, like so many other antecedent programs Army has lost the war again, badly. In terms of weight, recoil, durability and ballistics, expectations vs reality are crashing down on Army right now, hard.
Consider this my victory lap.
And next year, when the Army announces another hundreds of millions of dollars for some new secret-squirrel marketing program, give it six months. They'll be exposed as frauds before too long.
Edit: I should say that my extreme skepticism at the time was a bit uncomfortable. People who know more than me (and thus should know better) were saying the system worked. I didn't have access to any good data, but the math just didn't add up to me. I'm not a weapon designer, but I have a pretty good idea of what the normal ranges for technical specs are. Turns out, it really was all just marketing. Every time I think I'm too cynical, it turns out I wasn't quite cynical enough.

Notes -
Good points, in context of small arms, burst fire does make a good amount of sense.
Also, I'm suspecting there's a lot of things that haven't been tried. HEAT is probably not the best idea on account of the target being some sort of ceramic, but APDS would probably fit the bill nicely, as I imagine the plates themselves, when penetrated, do cause spalling, right ? APDS in tanks greatly increases penetration.
A plate. Which means, unless the guy is hit once or twice straight into a plate, he's just somewhat less likely to die. Which is very nice for the soldiers, but not really a gamechanger, as artillery is the bigger killer, and if they're shot at comprehensively, just as dead as an unarmored one.
Yet making a practical suit of armor that'd actually render the soldiers largely bulletproof to small arms, etc would still be prohibitively heavy, so you'd need either powered exoskeletons or bodybuilders and some cooling system.
APDS in small arms has been tried before. The major problem with it is that a long, skinny dart doesn't have very good killing power- it isn't carrying very much kinetic energy and due to its nature of being a long, skinny dart has a very hard time actually dumping that energy into the target. Other problems include requiring much more precision in manufacture to fly straight and the sabots have a tendency upon separation to bounce off the ground at Mach 4 and injure squadmates (a problem noted in the SPIW trials).
If I recall correctly, exploding ammunition for small arms has some laws of war constraining its use. It's quite trivial to make an explosive 30-caliber projectile (InRange has a few videos about this, with both German and Russian examples used in WW2), but your accuracy suffers a bit unless you make the projectile correctly and the cost per round from both a pure BOM and manufacturing cost perspective increases significantly.
He's significantly less likely to die. He's also much more likely to remain combat effective after taking a hit, which means that even if you end up causing eventual fatal injury to someone wearing this he's still probably going to be able to shoot back.
And while I agree that artillery is going to shred you no matter what armor you're wearing, that's not as effective when your enemy is either dug in (which a peer army could and would do) or irregular (in the case of civil war).
... I don't mean artillery of the kind the Taliban are using - a few rusty 120 mm mortars with a few shells, but the kind actual armies use.
You've heard the stories out of the Ukraine, or seen the pictures, right ? With accurate artillery fire, unless you have a deep shelter several meters under the ground, you're pretty much dead.
