As you just pointed out the M406 is intended for a underbarrel launcher the 30 and 35mm are primarily for a mounted auto launcher. And for the record it was mostly phased out for the M433 High explosive Dual Purpose round.
Chinese and Russian claims that their 30 and 35mm grenades are more lethal are valid since the 40mm grenades are antiquated.
you Cherry picked a round that matched your wanting. The M406 against unarmored targets is fine for what it was intended to do, Since then the 40mm round has continued to evolve with any number of options. if you pick one round and restrict yourself to that then yeah it will be antiquated.
it's more questionable since, as we know, the US gave up half the space on the 20mm OICW grenades for multirole functions,
??? What are you talking about?
The XM29 fired 1 type of round the XM1018 it only did one job High Explosive Air Burst. it had 2 warheads a battery and electronics It was not intended to do other jobs
The XM25 had more rounds ready but it was not firing one multifunction round, It had 6 types of rounds the XM1019 High Explosive Air bursting, The XM1047 black, the XM1049 AP round, The XM1050 training round, the XM1051 Target Practice - Spotter (TP-S), The XM1060 Thermobaric round.
we don't know how much a 40mm airburst would give up for similar battery /multirole functions.
Answer They give up the same amount of space as the 20mm even if they did add a bit more you still have a larger shell in which they sit. and by the way again a single function this is not like a Tank shell or bomb that can flex mission because they have the weight and size to get away with it. This is a single function round. It Airbursts or It AP's IT impact explodes or it Smokes not because there is some magical switch that changes its job but because it was designed that way.


As to the effectiveness of soft armor, I agree that it is shrapnel resistant at range, but you're looking at it as perfect protection, when it is not. Consider this: most militaries, including the United States Army, uses a combination of concussive and fragmentation grenades. The latter is for defensive purposes: you throw it from behind cover because the fragmentation grenades have an enormous lethal distance. Even when equipped with soft body armor, you are not proof against fragmentation grenades. Likewise, in Vietnam, "fragging" was a common way of murdering unwanted officers or other liabilities. Since these included NCOs, you'd imagine that people would not attempt to frag officers if soft body armor was proof.
Wow There is a whole heap of Stinking BS here.
First in Vietnam there are only 2 recorded incidents. Mostly it's just BS. second both incidents happened inside the wire the first was when a Grenade was thrown into the Company office the second was the Officer Billet in both case places where the intended victim would not be likely to be wearing a flak jacket. The Australians also had an incident like this and Again well the victim was asleep. In Iraq there 2 another two of this type again well the Soldiers were asleep or in a location where armor would likely not have been worn. And such cases do not get looked on kindly They are prosecuted.
When this happens it's premeditated so the killer does it when he feels there is no chance of his victim surviving.
By contrast there are a number of incidents where US Soldiers have placed themselves over hand grenades with a Kevlar helmet or flak vest and lived to tell the tale.

The problem for the 20mm round of a OICW is it's so small. Grenade rounds are a compromise They give up the explosive power of a traditionally rifle fire grenade for range and accuracy. The Hand grenade used by US forces in the Vietnam war was the M26 it had a 5.75 oz Comp B charge. That charge would be almost double the weight of the whole round of a 20mm Air bursting round complete with case propellent and primer. farther mre you consider we are talking about events almost 60 years ago now, Soft armor has improved. IT's not perfect but improved.
Concussive

Quit putting words in my mouth. I am saying that chances are the small yield vs modern armor with better fragmentation protection means that the 20mm shell is less likely to be as lethal vs a large system of same destination. That's why the US moved to 25mm fr it's XM25 because they deemed the 20mm not effective enough.

Actually, fragging incidents were manyfold, but only a small number of fatalities involved grenades. In regards to XM25 vs 40mm, actually, the XM1019 claims that it achieves 40mm grenade lethalities, so...

For fragging, read this article:

You know the funny thing is, I just reread my old posting on CDF, and as it turns out, I made almost the exact same comments regarding the difficulties of 20mm vs armored troops. But if the XM1019 achieves lethal radiuses equal to the 40mm grenade, then a grenade that is 20% smaller in one dimension should be able to achieve comparable lethalities. By volume, the grenade is 50% smaller, but since it's an explosive, not a projectile weapon, around 70% of lethal radius should be retained.

We have to remember that the old Type 24 hand grenade used by the PLA and NRA in WWII also had just 60g of TNT. And its explosive effect was plenty for most purposes.
With more modern explosive materials, there is no reason why the 85g 20mm cant have at least 45-50g of more powerful explosive material and achieves the same or even better effect, especially with air-burst.

President Xi inspects the QTS-11 (colloquially known as ZH-05).

Again that was still a larger 25mm round noth the PLA 20mm. Also likely based on the older 40mm. not the newer 40mm Airburst.

And that also works vs new generation 40mm Air burst rounds.

Note the 2 apitures over the barrel under the scope, likely the laser rangefinder.

note the Cluster of buttons over Mr. Xi's thumb The PLA regulates Right hand shooting so These are likely the inputs for the weapon. Interesting that the barrel seems to lack any kind of muzzle device on the 20mm. Also note the device on the Soldier's helmet, yet no eye protection.

You are reading too much into these pictures. Very amateur level, sorry to say.
Well nothing here that is new. So I picked some details.
I mean we have been covering and directing the system off and on for almost a decade now. So What's here? I mean ohhh wow XI holding one.... They are wearing Tibetan digital.

Although interesting 78 is right, unless NORINCO moves to make an Export version, the NAR series is not in any way related to the ZH05
