Ukrainian encrypted radio communications are all ready to defeat quantum computers.
Tactical mesh radio manufacturer Himera has partnered with Canadian cryptology company Quantropi to incorporate post-quantum cryptology.
1/ Image
The rapid development of quantum computing technology implies that the ability to break current cryptography methods is approaching.
Quantropi has developed special random-number algorithms designed to defeat even quantum computer attacks on Himera's encryption.
2/ Image
Himera has secured a government contract with an unnamed NATO country to supply their radios.
The system uses frequency hopping, a mesh cellular architecture, and low-power repeaters, which reduces the likelihood of detection and increases the network's resistance to jamming.

Russian blogger “Rybar” (Mikhail Zvinchuk) unfortunately is correct in this short summary of one the major capabilities that have been added to the “Geran-2” (Shahed) strike UAV system.
But he also reveals something important.

“Linked by a chain”
1/
“With each passing month, the "Gerani" become increasingly deadly and are equipped with technical devices that significantly enhance their combat capabilities. They now have network radio modems installed.
2/
“As a result, the drones can operate as relays and create a stable ‘mesh network.’ Among other things, this increases both the combat range of the devices and their resistance to interference.

The inevitability of autonomous drones and drone swarms is often dismissed with “microwave weapons will drop them all.”
EW and radio expert Serhii “Flash” reviews the state of development of this much-hyped anti-drone technology including the best-known, the “Leonidas” system:
1/ Image
“Electromagnetic weapons are being actively discussed online. Many different devices can be classified under this term based on their operating principles, but in my opinion, only the concept of directed ultra-high-frequency radiation looks realistic.
2/ Image
“This radiation induces currents in electronic components, causing them to fail or disrupting their operation.

Throughout the history of military technology, only one serial electromagnetic weapon system has been created by Russia, the ‘Ranet-E,’ which turned out to be…

Russian blogger Alex Kartavykh confirms that civilians are wary of signing very lucrative contracts because they know the Russian army consistently deceives.

“The issue is not with the civilian authorities, but with the employer — with how the Army has positioned itself.
1/ Image
“Since 2023, when contract soldiers for wartime were recruited en masse, many thousands of these contract soldiers have encountered deception from the employer and brought this knowledge home during leaves or after being discharged as disabled.
2/
“They shared with those around them — acquaintances, friends, simply interested applicants — how everything works. And it works like this:

— During recruitment, the Army promises a contract for 1 year.

Russian blogger “Atomic Cherry” argues that Ukrainian strikes on oil refineries will cause Moscow to perversely respond by forcing a reduction in consumption and the Russian economy itself.
1/
“Refined ideas about state governance imply the search for some highly effective symmetrical solution to any threat or crisis prospect.
2/
“Strikes on infrastructure should lead to the construction of a defensive perimeter; everything should be produced according to citizens' expectations to maintain their calm and well-being, necessarily organized and in the shortest possible time.

Blogger “Russian Engineer” reacts to “Madyar's” announcement of a big expansion of Ukraine's Unmanned Systems Forces.

“So the enemy already has 5 brigades with a fundamentally new organizational and staffing structure (ОШС), which are based on completely different…
1/ Image
“…principles compared to the rest of the army. That is, those elements that do not fit well in a regular infantry unit (the Ukrainians also have stories of sending lazy drone operators to assault units) are gathered there together to work on interaction, …
2/
“…new tactical schemes, test innovations, and constantly invent something themselves.

On our side, Rubicon performs a similar function, and the enemy gets very nervous when Rubicon operators start working in some area.

A delegation from my volunteer group Defense Tech for Ukraine spent two weeks in Ukraine meeting with military units and defense manufacturers.
My strongest impression was of Ukrainian civilians completely ignoring the frequent air raid sirens and calmly going about their day.
1/
Even a Shahed attack on Kharkiv one night had no apparent effect other than an earlier blackout.
The Milky Way was vivid in the middle of the city!
The Ukrainian people seem determined to ignore the hated Russians as much as possible, and refuse to let them affect their lives.
2/
I was worried we would find an exhausted and pessimistic nation, but the opposite was the case.
Military personnel and commanders are calm and confident.
Ukrainian defense manufacturers are inventive, and are steadily reducing reliance on Chinese components.
