Russian blogger “Philologist” provides a vivid description of overwhelming Ukrainian strength in drones near Pokrovsky.

“‼️ Information from the ground on the situation in the southern section of the Pokrovsky direction.

“We have no strength, we don't know what else to do. The sky is completely behind the [Ukrainians]. You can't go further than 3 km from Selidovo, they burn everything to hell.

There are a lot of comedians on optics, they monitor all the dirt roads 24/7. It's simply impossible to carry out a rotation. We walk 18 km. The issue of water, food, gasoline is acute. I'm not even talking about heating. The guys are literally freezing in their positions. There's nothing to bring in at all.
3/
“Of the comedians who are not on optics - Khokhol the found a window where we don't have electronic warfare: frequencies from 1020 to 2100. And he's actively working on them. The other day, two of our great fighters died: they simply didn't make it to their position. A comedian.
“They don't let you cut the roof off the loaves, like it's property on the balance sheet. You're riding in a loaf, like in a coffin, you
can't see or hear anything. Personal transport is prohibited.
5/
“Everything is working in Novotroitskoye and the immediate rear: from a barrel and MLRS to who knows what kind of missiles - we've never heard anything like that by the sound of it before. In short, it's fucked.
6/
“Nobody understands how to work in such an environment. The hohols are fucking us, fucking us really hard. If they don't start working with FABs, as densely as near Avdos - we won't get any further.”

Ukrainian EW expert Serhii “Flash” is in that area now installing passive radio receivers, and reports 10:1 reception of Ukrainian FPV video signals relative to Russian.

Russian blogger “Philologist” continues his candid analysis of Ukraine’s drone domination near Pokrovskii.
Ukraine’s system of separate drone battalions and now brigades allows vital concentration in critical areas.
1/
“In the current situation with the Pokrovsk direction, it is quite obvious that the combination of aerial reconnaissance of the lower skies with strike drones and artillery with an optimized organizational structure and a flexible system of control of fire and strike assets…
2/
“…allows the enemy to very effectively suppress the logistics of our troops.
The vulnerability of logistics is a general problem, the Pokrovsk direction here is simply a vivid illustrative example.

Why was Ukraine so far behind the Russians in committing to fiber optic FPVs?
A “Ukrainska Pravda” article explains that as EW jamming proliferated the Ukrainian Army decided to focus on machine vision, considering fiber FPVs too expensive.
1/ Image
With machine vision the FPV is controlled by the operator until a target is a few hundred meters away and designated.
He hands over control to algorithms trained by machine learning to recognize the target and fly the FPV until the target is hit.
This defeats local jamming.
2/ Image
"Machine vision isn't developing as fast as we'd expected", Oleksii Babenko, CEO of Ukrainian drone manufacturer Vyriy Drone, told Ekonomichna Pravda. Some manufacturers sent drones to the front with rather weak guidance algorithms.

A common objection to fiber optic FPVs is that they are a lot more expensive than radio FPVs.
A “Ukrainska Pravda” article discusses plummeting costs as Ukraine embraces fiber FPVs.
1/ Image
"Due to the high cost, it seemed that fibre-optic drones would never become widespread, but prices in the Ukrainian market are now falling", said [drone manufacturer Oleksii] Babenko. "Previously, the cheapest ones cost UAH 60,000–80,000 (approximately US$1,400–1,800)…
2/ Image
“…but now they are around 30,000 UAH (approximately US$700)." In his opinion, costs could become even lower if companies start independently manufacturing the key component – fibre-optic spools.
"We will produce the components ourselves.

If it was dangerousness before for Ukrainian self-propelled artillery to leave the safety of their protected enclosures, it is much worse now with fiber optic FPVs.
The increased range and immunity to vehicle-borne jammers of fiber FPVs is taking a toll.

In the sight of Russian fiber FPVs recently were 2S22 "Bogdan" self-propelled gun on the Tatra Phoenix 8x8 chassis, PzH-2000, and Caesar on the Tatra T815-7 chassis.

FPV motors can be optimized for either torque or thrust, but not both.
Torque is the “twisting” force the motor can deliver to the rotor and propeller.
Thrust is the force generated by the propeller that propels the drone upwards and forward.
1/ Image
Motors with higher torque can lift heavier drones or maintain altitude better at lower speeds or with larger propellers.
Higher torque also means better acceleration.
Torque is influenced by the size of the motor, the number of windings, and magnet strength.
2/ Image
Thrust determines how much weight the drone can lift off the ground.
More thrust means the drone can carry more payload or fly faster.
High thrust allows for more aggressive maneuvers, quicker climbs, and faster speed changes.

Russians like to publish their poetry on Telegram.
Here is an example, in this case reinforcing the Russian death cult of suicide rather than surrender.

"One day the war will end..." 🙏💪🇷🇺❤
1/ Image
One day the war will end....
"Gatherings" will not flicker in the feed.
Silence will come to the world,
Volunteers will breathe a sigh of relief.
2/
There will be no fear of calls,
From midnight text messages.
And hundreds of requests from boys,
From mothers, from wives and daughters.
