mixing drive models is certainly not going to do any harm

It may, performance-wise, but usually not enough to matter for a small self-hosting servers.

Mirnograd : the Russians hit 2 missiles from the S-300 air defense system. The police department was destroyed.

Is this a translation error? Did the S300 really hit two Ukrainian S300 air defence missiles? That would be an unexpected operational success. I assume a "with" is missing: "the Russians hit with 2 missiles ..."

I think you are spot on.

S300 are anti-aircraft missiles. Converting them for surface-to-surface use is very inaccurate. So they are not targeting specific civilian objects, they just don't care. If they aim them roughly at civilian areas, it can still be a war crime, and it is tactically and strategically mostly useless.

I wouldn’t be surprised if

Neither would I. Just saying that "smoking at the workplace" alone won't suffice. Unlike in, say, a ~~fireworks~~ munitions factory.

The way I see it: it is either mostly ineffective (against infrastructure) or a war crime if used again against people (civilians or combatants).

Can transformer cooling oil form flammable vapour? Maybe, I guess, if it's hot enough, but I'm not sure. But when the transformer gets hot and explodes it may cause an oil spray fine enough to create a fireball, which may look similar. The first stage of a "proper" BLEVE is normally the "expanding vapor" cloud, which is visible as such, before it has mixed with air sufficiently (and/or reaches an ignition source) to burn and form the fireball. Then again, in smaller ones, and in the dark, the vapour cloud may be so short-lived that it cannot be seen.

Not sure this has been the official "explanation" this time, but looking at it from a technical side, there isn't normally anything in a transformer flammable enough to be ignited by a cigarette, even if you could drop it directly into the cooling oil (which you can't: they are normally sealed). My understanding is that you need a sustained arc over several minutes of "normal" electric current, or several lightning strikes to heat up the oil enough to catch fire. That requires some major fault. I guess a suitable type of warhead could cause it eventually, but not immediately.

What are we looking at? Incendiary cluster munitions?

[–] Hopfgeist@feddit.de 5 points 2 years ago

Yes, or other light aircraft. Not military. But what is or was in the building is anyone's guess.

[–] Hopfgeist@feddit.de 2 points 2 years ago

I heard about 60 from Jordan. Have to check my sources.

That thing still looks like a combat robot from a science fiction movie. Especially the muzzle devices look so silly. I know they are important as they measure the actual muzzle velocity, which helps to make it as accurate as it is, but still:

They need more Gepards! They can do it with fewer shots, I guess. But even though slow and low, hitting those things with manually tracked FlaK is no small feat. Well done!
