1/ Tens of gigabytes of secret data on Russia's strategic electronic warfare systems has been hacked by the pro-Ukrainian Russian Volunteer Corps (RDK). They say that Russia's EW shield is "not just fragile - it's full of holes" due to multiple flaws and vulnerabilities. ⬇️ Image
2/ Two weeks ago, the RDK announced that it had obtained a large quantity of data on Russia's EW systems, including technical specifications, diagrams, official correspondence, equipment setup methods, drawings, test reports, and functional information.
3/ RDK commander 'Fortuna' says that "We got more than just the external appearance. We see the internal logic, architecture, connections between nodes, we know who designed it, which companies supplied the units, which research institutes are responsible for the developments."
4/ "We received a number of important military developments along with protocols, engineering solutions and approvals from the Russian Ministry of Defence. In addition, we managed to establish the entire chain of enterprises involved in production and supply.
5/ "And it is also important that all the persons involved in the development and creation of these stations were identified. Upon completion of the operation, the RDK had their names, addresses, car numbers, places of work."
6/ RDK announced in a YouTube video that it had obtained data on the following:

🔺 "ANCHAR-K — a polar warfare naval station. An automated station for electronic suppression of satellite communication lines in Arctic conditions. It is installed on icebreaker-class ships. Image
7/ "Developed as a response to the vulnerability of the Russian Federation in high-latitude areas."
8/ The system is intended to disrupt signals from satellites, aviation radars and ship navigation. However, the documents obtained by the RDK indicate that it is not capable of resisting Arctic conditions, including wind, cold and icing.
9/ According to the RDK, "When the ship maneuvers, the Anchar loses tracking. The guidance time is more than four minutes. In the event of a failure, the entire system is switched off." Its location is exposed when it is in operation.
10/ 🔺 "OZON-MEI — over-the-horizon. Over-the-horizon radar project using the evaporation waveguide effect. It works by forming a plasma channel in the near-surface atmosphere."
11/🔺 "Tirada-2.3 — "Interference". Satellite communications electronic suppression station. Part of the Tirada-2S complex."

According to the RDK, this is a narrow-target system for disabling satellite communications which uses directional antennas to focus on specific targets. Image
12/ Operating in ranges from 225 MHz to 15 GHz, it is used to temporarily disrupt communications with US and British military satellites (WGS, MUOS, Skynet).
13/ 'Fortuna' says: "Such a complex jams communications and also generates false signals. For example, a drone flying over the Bryansk region may "think" that it is over Ethiopia. Disorientation and substitution of coordinates occur."
14/🔺 "NMS REP DDV — suppression radio brain. Ground-based mobile station for suppressing long-range satellite communications. Controls other electronic warfare systems. Suppresses FleetSatcom, Milstar, MUOS, etc. links."
15/ The RDK desribes this as a key element of Russian signal suppression technology:

“This is a radio brain, everything depends on it: it determines radiation modes, types of interference, phasing."
16/ However, they say that it has serious flaws. It is reported to be extremely sensitive to weather, vibrations, requires complex settings and a stable power supply. The system copes poorly with combat conditions.
17/🔺 "Software modules, OS, CORVETTE. Operating systems and software modules used for protection and work with electronic warfare. We understand the architecture, but will not disclose all the security details."
18/ The hacked documents also reveal that Russia exploits China's satellites, apparently without China's knowledge. "Russia uses civilian Chinese satellites to cover the calibration of its systems."
19/ "That is, Russian electronic warfare systems are posing as terminals of the PRC’s civilian fleet in the Pacific Ocean. China has not been officially notified of this. If a signal is detected, Russia is betting that the responsibility will fall on the Chinese channel.
20/ "This is a risky game. Sooner or later, China will understand this. And we already know which satellites they “hang on to,” which channels they mimic. This is an extremely interesting and unexpected observation."
21/ 'Fortuna' says that Russian strategic electronic warfare systems suffer from the lack of an operational ecosystem. "This is a huge, overloaded structure, not ready for a real war."
22/ Russia has invested heavily in its EW systems to compensate for its relative lack of satellites, compared to the United States or China. The leak is likely to be a considerable setback, as it will enable Ukraine's Western partners to develop countermeasures. /end

1/ THE HUNGARIAN REVOLUTION, DAY 2

69 years ago today, Hungary's revolution was entering its second day as the population revolted against the Communist government. This thread continues the day-by-day story of the revolution, as the Soviets became involved for the first time. Image
2/ (For day 1, see the thread below).
3/ In the early hours of 24 October 1956, Hungarian Communist leader Ernő Gerő appeals to Moscow to help suppress the "counter-revolutionary" uprising. At 02:00, Soviet defence minister Georgy Zhukov authorises the deployment of Red Army troops. Image

1/ THE HUNGARIAN REVOLUTION, DAY 1:

69 years ago today, Hungary rose up against a tyrannical Communist government backed by the Soviet Union. With Hungary currently under another pro-Russian leader, the story of the Hungarian Revolution is still strongly relevant. Image
2/ Immediately prior to the revolution, Hungary's Stalinist regime was deeply unpopular. Hungary's economy was struggling, Communist leader Mátyás Rákosi had been deposed by the Soviets over destalinisation, and the many past abuses of the regime were becoming public knowledge. Image
3/ A student protest sparked the revolution, followed by the Hungarian Writers' Union declaring its support for anti-communist reformers in Poland and laying a symbolic wreath at the statue of General Józef Zachariasz Bem, a hero of the Hungarian Revolution of 1848. Image

1/ A Russian soldier says that every man in his unit has been ordered to shoot his comrades if they try to flee, or face being shot themselves as a punishment. He describes an atmosphere of paranoia amidst huge losses, which he puts at 95% of men going into assaults. ⬇️
2/ The man says that he is from Altai Krai, where he was made to sign a contract to avoid going to trial for an unspecified offence for which he faced eight years' imprisonment. He has been serving in the army for six months and is currently a stormtrooper.
3/ He says that "every second person here drinks, to gain courage, to go somewhere [on a mission]." The reason why is understandable: "A hundred people would join a group [for a mission], take a position, and only five would come out."

1/ A Russian city is literally drowning in human waste due to the failure of its sewage system. It's worn out but hasn't been replaced or repaired due to a lack of funding. It's a vivid illustration of the costs imposed by Russia's money being redirected to the war in Ukraine. ⬇️
2/ Balakhna is an historic city of around 51,000 people, founded in 1474 on the banks of the Volga River about 32 kilometers (20 mi) north of Nizhny Novgorod. However, its underfunded sewage system has collapsed, with the result that "the city is literally flooded with shit". Image
Image
3/ Balakhna native Alexander Kartavykh – a Russian warblogger – has been highlighting the city's problems in a series of posts on Telegram. He says that "the pumps aren't working, everything's broken, it's a complete and utter disaster."

1/ Russian forces are making extensive use of infiltration tactics in place of the notorious 'meat assaults', according to a new report by @jack_watling. However, a Russian warblogger says that this is costing 2 or 3 times as many cumulative casualties as massed assaults. ⬇️
2/ The DShRG Rusich Telegram channel has published a video taken by a Russian soldier on an infiltration mission. He follows a path along a treeline which was used by many other Russian soldiers on similar missions – dozens of whom can be seen lying dead along the way.
3/ The channel's author writes:

"The tactic of infiltrating small groups (2-3 people), unfortunately, often results in greater losses than a single massive assault. Yes, on video, it looks tragic from the enemy side, with several units of equipment being destroyed."

1/ A Russian colonel reportedly died of cardiac arrest after it was discovered during a rotation that he had been lying to his superiors about his division's control of territory in the Kherson region. ⬇️ Image
2/ Colonel Alexey Vladlenovich Plisov, callsign 'Ryazan', was the commander of the Russian 70th Motor Rifle Division of the 18th Combined Arms Army. The division was located on the left bank of the Dnipro river.
3/ Plisov is said to have repeatedly reported to his superiors that most of the islands in the Kherson region were under Russian control. However, Ukrainian reports and independent assessments have consistently assigned the islands to the 'grey zone' controlled by neither side. Image
