Further excerpts from the interview with the Commander of the Ukrainian Special Electronic Support Center, on how to improve tactical EW.

“Firstly, the means must be easy to modernize because frequencies and application algorithms constantly change on the front.
1/ Image “Moreover, the Russians can switch both to new frequencies and return to old ones. Accordingly, the means must also be changed quickly. Unfortunately, most systems are currently tailored to specific characteristics, and to change them, new ones must be purchased.

Russian blogger Ilya Mersh (“Older than the Edda”) argues that the drone revolution will force the use of very expensive heavily armored APCs and tanks with multiple anti-FPV systems.

“The era of drones, which has currently completely changed the face of war, …
1/ Image “…will very soon lead to the revival of heavy armored vehicles. Tanks and heavy APCs/IFVs are what will be able, if not to completely neutralize the drone threat, then at least to ensure breakthroughs and the delivery of soldiers, ammunition, and supplies to the front line.

More Russian “Gerbera” reconnaissance UAVs are armed with OFBCh-2 fragmentation warheads.
The inertial impact UZ-2 fuze is also used on OFZBCh-50 “Geran-2” warheads.
The fuze is armed by the UAV's flight controller (FC) shortly before impact, likely prompted by altitude.

Image Just before the flight a mechanical safety that partly locks the primer mechanism from moving into alignment is released, but the fuze is not yet armed.

A Ukrainian primer explains how Russia gathers information from cell phone use in the grey zone and its consequences.

“Why you need to be careful when using a phone at the front line. Let's consider the issue using the example of the ELINT system (Electronic Intelligence).
1/ Image “ELINT usually works only on group targets. Three or more phones in one place in the forest and the artillery gets the target designation. The radio intelligence complex shows the SIM card number, the phone's serial number, and the signal strength from the phone.

Russian blogger “Military Manager” reveals the tremendous importance of the huge Ukrainian “Baba Yaga” heavy drone fleet, while the Russian's hardly have any.

“The heavy drones of the Ukrainians started causing problems literally from the moment they appeared on the front.

The progression in capabilities of the Russian UMPK guided glide bomb series for FAB-500 aerial bombs

The original UMPK for the FAB-500 M62 aerial bomb was guided by a 4-element “Cometa M4” CRPA jam-resistant satellite navigation system, with up to 75 km in range.
1/ Image The first major upgrade is the extended-range UMPK-PD, with increasingly difficult to jam 8 and then 12 element “Cometa M8–12” satellite navigation.
Extended wings and a new FAB-500T bomb with better aerodynamic qualities increases the range to 100 km.

A Russian soldier describes in detail the deadly conditions on the frontline.

“Small groups are fighting a huge war. An ‘Opornik’ [dugout] can be held by a handful: two, three, or four people. The line of combat contact has completely changed.

Now the equipment is stationed tens of kilometers away from the LBS.

VictoryDrones's Maria Berlinska argues that victory for Ukraine will come by winning the race to an army of fully autonomous drones, and not with Tomahawks.

“I do not claim to have the ultimate truth; this is purely my broad vision of the next stages of the technological war.
1/ Image “A conditional division.
Just to understand the overall picture and trends.

The first stage - drones are controlled by humans directly on the battlefield. Mainly for artillery fire correction and reconnaissance. The first attempts at strike operations - drops, kamikaze.

A Russian manual entitled “Countering ‘Baba Yaga’ Type Drones” starts with vivid descriptions of the capabilities of three types of Ukrainian bombers.
Described first in some selected excerpts from the manual is the Nemesis drone, a heavy quadcopter guided by Starlink.

Military analyst Yigal Levin vividly explains that many Westerners like Mark Rutte don’t seem to comprehend that a Russian “lives in an invented world” and only understands strength.

The logic is clear — it's the condescending logic of a noble gentleman: if you're the boss and the alpha, and there's a pygmy jumping at your feet, you don't necessarily have to kick him, you can just smile — …

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:

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

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.

Two Russian bloggers have opposing views on the effectiveness of steel mesh at protecting energy infrastructure from Ukrainian long-range strike UAVs.
“Two Majors” is scornful of these, arguing that the blast wave of a 50 kg warhead is hardly mitigated at a 2 meter stand-off.
1/ “We get a blast wave pressure of 9089 kPa.

That is, at the moment of the explosion, at 2 meters from the top of the tank, the pressure of the blast wave (excluding damaging elements) on one square meter of the protected object will be 9,089,000 N/m².
