I question that. At what point does one stop saying "it's a training issue" because you can also apply that to bolt hold open, bolt release, and adjustable stock and sights. At the end of the day, all of it is training issues but the point the original poster and me were trying to make is improving the platform so it's better. I think the PLA are starting to get this as well and all the modernization going on right now seems like dipping their toes in the water to test it.
Good question ,it makes trivial difference in my opinion in the bigger picture of peer combat because the nature of small arms.
These advancements are from a Civilian perspective of fire arm use ,and imagining the battle field with infantry shooting each other like we have seen in none peer environment of war on terror.
I my opinion the combat effective fire power of a infantry squad at end of 1945 with M1 m1 Garand and BAR is about is about 70% (excluding ,un-organic to the squad, and the IFV) of that infantry squad of a 2022 , the main cause of the difference is due to magazine size , and the amount of ammo they carry , and sights.
This also means that just about every mission carried out today by a infantry squad can be carried out by one from 1945 , it would take them longer , but modern infantry squad fire and mauver remained the same.
What did change drastically is everything else in the battle space , a infantry squad has a IFV now days which has more powerful of a cannon and sensors then the infantry can hope to carry, and the firepower and information on call for a squad is now logarithmically higher then back in WW2 both in direct and direct , the kill chain completion time went from few minutes to dozens seconds.
This is back up with the fact ,that most combat casualty is not a gun shot ,still to this day they the most casualty are caused by shrapnel , this means that by far the most important weapon for the squad is it's eye and radio, not the gun in their hand.
So from this perspective I would agree with you that yes , the things you said is a improving the platform, but I would dwell to much on it, even if it is the perfect small arms , it matters a little in a battel space when you are been shelled from a enemy you can't see .
Or even you can see it often it armored and you might not have a can opener for that threat.
