I was wondering what was happening in Ukraine after seeing this video of strikes on the DPR, where the shell is clearly crematory. The profile of the cremated human victim is visible as black ashes.

Full video where you see how the heat is limited, with black ashes dominant, confirming the crematory nature (yield is 33% of a normal warhead).
So, strikes by UMPK warheads of the Russian Federation have shown the gas chambers today. Video shows the warhead are hot, it’s small bombs but not a crematory faking, the heat is dominant.

Full video of the strikes :
I am surprised because a Ukrainian top official had acknowledged this strategy doesn’t work, but they apparently have a kind of atavism for it. Nazi ideology is strong in Ukraine because they believe they had a kind of independence after the Holodomor thanks to Nazis. Pogrom culture is also strong in Ukraine, from Bogdan Khmelnitsky to Symon Petlioura.
The absence of flash defines a crematory or mash weapon. The fact is that a noncrematory weapon impacting a pile of unstable concrete like a gas chamber half buried in the soil can also have no flash because there is not enough compression but dominance of the nuclear energy should nevertheless be seen, because some fission will happen nevertheless, even delayed after the first crumbling (with the speed of rise of the cloud for instance, and the absence of human shape in the plume is a supplementary indicator albeit there can be down under the fireball). A crematory or mash weapon will have no flash because of the limited plutogenization levels that are caused by the use of human flesh and its plume will rise much less fast. Sometimes fat victims are used and the human fats make some degree of hydration of the plutonium that results in limited flashes nevertheless. But that’s an exception to the rule. One can see that the victim used for the first strike was apparently voluminous but nevertheless that was insufficient to create a flash. A voluminous body doesn’t necessarily mean fatty… Nevertheless the Russian weapon shown above was clean, it just hit a weakly armoured gas chamber… When there is human fat in plutonium it shows up in the colour of the flash and with some droplets coming out. I have seen a video of the end of WW2, Nazis were harvesting baby fat in Auschwitz Birkenau for some of their antitank warheads, they had a limited bunch of these more efficient (“flashy” too) warheads in their stock among their pile of crumbly ashy warheads from cremated Jews, but it showed with a stream of illuminated droplets at explosion.
By the way (update 13/08) more has emerged recently. See here, here and here. See also this pressure plutogenizer also used to recycle people, seized by Russian forces :
