Secret 80's technology

This one was cool assuming it's true.

The Pentagon's support to Israel also included the transfer of some of the most cutting-edge technologies used by the U.S. special operations and intelligence communities: so-called "black box" devices that it had previously been illegal to share with American partners, no matter how close the relationships. The Israelis were allowed to use and carry these devices, but were not to be told how they worked and were required to return them after the mission.

One of these gadgets was described to the The High Side by an official briefed on the matter as a "Stingray on steroids," a device that sucks voice signals from cell phone activity straight out of the air and processes them using artificial intelligence-enabled voice recognition technology. If the device finds a voice belonging to a known terrorist, the data is then forwarded to human technical experts for further analysis. Other U.S. technologies provided to Israel included advanced optics and thermal imaging technology, according to a U.S. individual briefed on the "black box" and familiar with the technology transfer.

Among the technologies on the drones was a type of radar that can penetrate concrete structures and detect heat signatures within, as well as see underground to a certain depth.

ISR platforms that can detect heat signatures through around ten feet of concrete failed to find any hostages, according to a U.S. government official. Sensor packages placed in Gaza disguised as rocks or rubble also failed to help geolocate any of the captives, the official went on to say, adding that sensors that can "smell" burning excrement or human corpses likewise detected nothing significant. (The use of these technologies did not involve any U.S. military personnel entering Gaza, according to U.S. officials.)

I don't know if any mainstream journos covered it beyond that substack guy. But it seems plausible.
