Russian Igor “Strelkov” Girkin writes from his prison cell of his surprise and new depths of pessimism regarding the Special Operation after Ukraine's great raid on Moscow.

“Brothers, sisters, friends, and colleagues!
1/ Image “I understand that my letter will not reach you for quite some time because, it seems, it will have already lost its relevance by then. Nevertheless, I believe it is necessary to write a few words about the current situation and my impressions of it.

In a blog entitled “Unthinkable,” Russian war correspondent and blogger Nikita Tretyakov is deeply critical of the results and consequences of Russia’s disastrous “special operation” in Ukraine.
1/ “Sergey Lavrov:
‘I don’t want to even suspect that Alaska, just like European actions, was designed to buy time for the rearmament of the Kiev regime, which would last longer than the First and Great Patriotic Wars.’

Ukrainian Unmanned Systems commander “Madyar” has a message for the Bunker Grandpa in Moscow.

“Moscow and Bunker Grandpa will cling to Crimea until the very end, like it’s the main trophy of this war, even in ‘island’ mode.
1/ Image “Of course they will. It’s the cornerstone of their ‘greatness’ ideology and comes with a whole pile of bonuses: the ‘Russia's internal Azov Sea’ and all that other crap.
That said, using Crimea as a launchpad to attack Ukraine is already pure military absurdity.

Led by Minister of Defense Mykhailo Fedorov, Ukraine is forging vital partnerships with America tech billionaires — such as Alex Karp of Palantir, Eric Schmidt from Google, and Elon Musk.
These collaborations will deliver a decisive advantage over Russia in AI-enabled systems.
1/ Image Alex Karp wants to build AI systems that would give the U.S. a decisive technological edge in future wars.
Ukraine possesses a massive dataset and a rich library of real-world combat video that is highly valuable for training advanced AI models.

Russian blogger “Rybar” claims that 60% of Ukrainian long-range strike UAVs are launched without a warhead.
Their purpose is to saturate Russian air defenses and force them to engage, because decoy UAVs cannot be distinguished from armed ones.
1/ Image This way, expensive surface-to-air missiles are traded for cheap UAVs, emptying the batteries and steadily exhausting the total remaining missile resources.

Prominent Russian blogger “Veteran’s Notes” laments the “humiliating” failure of the State to provide heavy lift drones like the Ukrainian “Vampire.”
Instead, Russian frontline units must be supplied by human bearers and a handful of salvaged Ukrainian drones.
1/ Image “Recently, our unit lost a trophy drone, which I mentioned earlier.

It served the Russian army faithfully for exactly one month.

The Russians recovered an 8-element GPS-jamming-resistant CRPA satellite navigation system that is apparently from an AGM-188A “Rusty Dagger” cruise missile.
This is a 930-km range, low-cost missile to be carried by F-16s and intended primarily for use by Ukraine.
1/ Image
Image Initial deliveries are scheduled for October, but the recovered device may indicate that a test batch has already been sent to Ukraine.
The Russians claim that the CRPA was made by Zone 5 Technologies, the developer and manufacturer of the missile.

He believes a turning point in the war is approaching.

Since its disconnection from Starlink, Russia is urgently pushing forward its own LEO high-speed satellite constellation called “Rassvet”.
Ukrainian communications expert Serhii “Flash” Beskrestnov analyses its status and prospects.
1/ Image “1. The enemy needs a ‘Russian StarLink’. Undoubtedly, Russia understands the importance of a high-speed data transmission system via low-orbit satellites, and it would be foolish to think they wouldn't pursue this direction. The question is just about timing.

Russian sources report that Ukraine has started dropping anti-vehicle landmines on the M-14 highway between Melitopol and Mariupol.
This key logistical route to Crimea is 100–150 km from the front lines and would require fixed-wing UAVs to reach that far.​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​
1/Image This highway has been the primary focus of Ukraine’s sharp rise in strikes on Russian trucks using mid-range UAVs like the “Hornet.”
Landmines at operational depth on this and other routes will greatly increase pressure on Russian logistics.

Serhii “Flash” clarifies new Russian tactics that combine “Geran-2” attacks on Ukrainian air defense units while another UAV simultaneously strikes the main target.
First, a “Gerbera” reconnaissance UAV studies the air defenses to determine their movements and locations.
1/ Then, a double strike is applied—one Geran-2 strikes and distracts the ground-based air defenses, while another attacks the target.
“Flash” advises using camouflage, changing to backup positions, and closely monitoring reconnaissance UAV flights.

Russian blogger “Philologist in Ambush” (Svyatoslav Golikov) warns Ukraine is no longer just flooding the front with drones.
It is building an adaptive, networked strike system that is increasingly outpacing Russian EW and logistics defenses.

Russian blogger Alexei Rogozin warns that the American company Palantir has provided Ukraine with AI tools that process vast amounts of data to integrate with and leverage long-range UAV strike capabilities.

The Russians have developed a new radio reconnaissance system called the “Meshtastic-Sniffer” for detecting and analyzing Ukrainian Meshtastic/LoRa mesh networks.
Using multiple synchronized receivers, it can geolocate transmitting nodes via TDOA (Time Difference of Arrival).
1/ Image It is important to note that mesh networks and Meshtastic are different.
A mesh network is a general communications architecture in which devices relay data to one another without a central base station.
Meshtastic is one specific implementation that uses LoRa radio modules.

The sorry state of Russian surface warship construction is exemplified by the long-delayed commissioning of the small 800-ton missile ship Burya.
Laid down in December 2016 and launched in October 2018, it then sat idle for years awaiting its diesel engines.
1/ Image Even then, sea trials dragged on for another three-and-a-half years due to chronic engine problems.
Originally, German high-speed diesel engines had been intended, but sanctions imposed after the 2014 annexation of Crimea cut off supplies.

“FPV ABOVE THE HEAD: SECONDS MAKE THE DIFFERENCE.

The Russians have failed to develop an equivalent of Ukraine’s successful Sky Fortress acoustic system that detects and tracks Shahed UAVs
Russian bloggers are angry that a recent 1,800 km Ukrainian UAV strike past the Ural Mountains went undetected by Russian air defenses.
1/ Image Sky Fortress is a system of microphones mounted on cellular towers connected to central processing nodes.
AI algorithms detect the distinctive sound of Geran-2 (Shahed) engines, enabling mobile ground fire teams to be dispatched and stationed ahead of the UAV's flight path.

Russian blogger “Military Manager” has described the tactics of Russian “Molniya” strike UAVs used to minimize the heavy losses occurring to Ukrainian interceptor FPVs.

“1. Your target is in a forest belt in the enemy's notional rear area. 10-15km from the front line.
1/ “Several villages behind the LBS [Line of Contact] are directly on the route. How will you fly? The answer is obvious. Of course, we will bypass all NP [settlements] and the forest strips that are part of it.

I just reread Adam Tooze's magisterial The Wages of Destruction: The Making and Breaking of the Nazi Economy, and the parallels with Russia's deteriorating wartime economy are striking.
By the late 1930s, Hitler's massive rearmament program consumed 20% of national income.
1/ The result was a civilian sector starved of labor, materials, and capital.
Consumer goods production was squeezed, infrastructure lagged, and bottlenecks spread across the country.
Despite headline armaments growth, overall productivity was undermined.

Russian milblogger “Two Majors” complains that Ukraine is trying to push Russia out of Africa.

✨As a result, Ukraine plans to obtain a logistics and production center for all of West Africa.
