Ukrainian ground drone (UGV) rigged to launch S-5 unguided rockets from the pods normally seen on helicopters like Mi-24 HIND.
Not the first time aircraft rocket pods have been ground launched, but this is mad max and terminator combined.

‼️ Russia produces about 170 Shaheds per day. Plans to produce much more, — GUR
Along with the Shaheds, the Russians use decoy drones such as "Gerbera-2" and "Parodiya". Their purpose is to clear the way for real "Shaheds", which carry a lot of explosives.

This is how you do a special military operation
#Ukrainian media reports that more than 40 Russian military aircraft are on fire.
Right now, the Security Service of #Ukraine is conducting a large-scale special operation to destroy strategic bombers. A-50, Tu-95 and Tu-22 M3 were hit. Enemy aircraft suffered losses of more than $2 billion.

I believe the Kaliningrad and St Petersburg (and more?) spoof-jammers have increased their reach significantly.
The area around Baltic Sea presently affected by electronic warfare directed at GNSS/GPS-receivers is enormous, larger than before.
Bbl with a timelapse. Nb, this is reach at 10-30k ft.

A new paper shows all language models converge on the same "universal geometry" of meaning. Researchers can translate between ANY model's embeddings without seeing the original text.
