                    "Ukraine claims it has recently regained about 125 sq. km. of territory near the town of Lyman in the eastern Donetsk region during what has been dubbed Operation Vivaldi. Rodion Kudryashov, a Ukrainian colonel and deputy commander of the Third Army Corps, offered some insights into this offensive and what made it different.\n\n\n\nThough the operation is still ongoing, the success of Vivaldi began long before any troop movements, Kudryashov explained in an editorial he published in Ukrainian Pravda.\n\n\n\nUkraine is making advances near the town of Lyman, located in the Donetsk region. (Google Earth) \n\n\n\n\u201cAfter the Third Army Corps was formed, we changed the command system of its subordinate units,\u201d he noted. \u201cSome brigades came to the corps after very heavy fighting, with losses, manning problems and, most importantly, eroded trust in their leadership.\u201d\n\n\n\nThird Army Corps Commander Brig. Gen. Andriy Biletsky \u201cthen set out one of our key principles: a commander must be responsible for the entire cycle, from training a soldier to the result on the battlefield,\u201d Kudryashov pointed out. \u201cIn some places that meant replacing a commander. In others it meant restructuring a staff or strengthening the NCO chain. In some cases we had to build, almost from scratch, processes that on paper should have been working long ago.\u201d\n\n\n\nAt issue was changing the culture from a more rigid Soviet-era model, with a cumbersome chain of command, to a modern, more flexible one better suited for the current conflict.\n\n\n\n\u201cA modern commander has to handle an enormous flow of information and make decisions quickly,\u201d the deputy commander proffered. \u201cHe has to understand what unmanned systems, logistics, reconnaissance and adjacent units can do, while not smothering initiative at lower levels with endless approvals. An army where every decision takes hours to travel up and down the chain loses to an army that makes the same trip in minutes.\u201d\n\n\n\nOnce those changes were put in place, the Third Army Corps had to first stop Russian advances in the sector before it could move forward.\n\n\n\n\n\n\nVIVALDI \ud83c\udfbc\ud83c\udfb6GoPro footage from Ukrainian assault troops who took part in the Vivaldi counteroffensive, which resulted in the liberation of five settlements in the Lyman direction. pic.twitter.com/2SVXSKlEX0\u2014 \ud835\udd17\ud835\udd25\ud835\udd22 \ud835\udd6f\ud835\udd22\ud835\udd1e\ud835\udd21 \ud835\udd6f\ud835\udd26\ud835\udd30\ud835\udd31\ud835\udd2f\ud835\udd26\ud835\udd20\ud835\udd31 \ud83e\udda9\ud83c\uddec\ud83c\uddea\ud83c\uddfa\ud83c\udde6\ud83c\uddfa\ud83c\uddf2\ud83c\uddec\ud83c\uddf7 (@TheDeadDistrict) September 17, 2026\n\n\n\n\n\n\u201cWhen the corps took over its area of responsibility, our first task was not an offensive,\u201d the officer said. \u201cWe had to stop the situation from deteriorating and stabilize the forward edge.\u201d\n\n\n\n\u201cThe enemy was pressing. In some sectors our combat formations were losing cohesion,\u201d he underscored. \u201cThe Russians were actively using infiltration tactics: small groups seeped between positions, massed in our rear, threatened logistics and gradually eroded the defensive line.\u201d\n\n\n\n\u201cWe had to stabilize the forward edge and stop the infiltration,\u201d Kudryashov said. \u201cWe had to rebuild command, put in commanders capable of making decisions, form new teams and reconstitute units. We had to set up the surveillance-and-strike system and sustain the front line. We had to stockpile ammunition, drones and other resources, understand the enemy, and plan the next step before the previous one was finished. Only after that could we move forward.\u201d\n\n\n\nBy June, the corps was able to secure the front \u201cin the sector from Borova to Lyman and eliminate the enemy\u2019s infiltration zones,\u201d Kudryashov continued. \u201cThat sounds less impressive than the word \u2018offensive,\u2019 but no offensive ever happens without it.\u201d\n\n\n\n\u201cYou cannot plan a complex operation if you don\u2019t know where your forward edge will be tomorrow,\u201d the deputy commander extrapolated. \u201cYou cannot build up forces if your logistics are constantly under threat. And you cannot form a strike group if your units are always forced to patch new breaches. So the first phase of \u2018Vivaldi\u2019 was not an advance at all. It was creating the conditions that made an advance possible in the first place.\u201d\n\n\n\nOnce the front was stabilized, the next step was shaping the battlefield for the offensive. The corps\u2019 unmanned systems units went to work against Russian logistics, striking a pipeline and depots. That forced the enemy to change its fuel and lubricant supply routes.\n\n\n\n\n\n\nUkraine\u2019s 3rd Army Corps released new footage of search-and-strike operations on the Lyman front. FPV drone operators from the 60th Mechanized Brigade\u2019s FATUM unit targeted Russian armored vehicles, a Grad multiple rocket launcher and personnel. #Ukraine pic.twitter.com/1iNG7z2N1c\u2014 NOELREPORTS \ud83c\uddea\ud83c\uddfa \ud83c\uddfa\ud83c\udde6 (@NOELreports) September 24, 2026\n\n\n\n\n\n\u201cThe operation also involved the corps\u2019 brigades, its reconnaissance and unmanned units, and attached forces from the SSO (Special Operations Forces), GUR (Defense Intelligence) and DPSU (State Border Guard Service),\u201d the deputy commander said. \u201cTo counter infiltration, a joint headquarters was set up to coordinate special and reconnaissance units at the tactical level under a single concept.\u201d\n\n\n\n\u201cIn my view, this is one of the main characteristics of modern war,\u201d he further stated. \u201cIt is not 10 strong units that each fight well on their own. It is 10 different elements that start working as one system at the right moment.\u201d\n\n\n\n\n\n\nAn interesting new detail from Ukraine\u2019s 3rd Army Corps about Operation Vivaldi on the Lyman axis.The Corps says Ukrainian forces carried out a flanking maneuver and, for the first time, airlifted unmanned ground vehicles behind Russian lines, while also suppressing Russian\u2026 https://t.co/ZEq8C75bN4 pic.twitter.com/KgKcZ0Zs2P\u2014 Special Kherson Cat \ud83d\udc08\ud83c\uddfa\ud83c\udde6 (@bayraktar_1love) September 20, 2026\n\n\n\n\n\nThe influential, Kremlin-connected Rybar Telegram channel has acknowledged Ukrainian gains in this sector.\n\n\n\n\u201cIn the first half of summer, Russian units gradually advanced in Lyman,\u201d Rybar wrote this morning. \u201cHowever, in August, the enemy launched counterattacks and, by the first week of September, regained some positions, and also began attempts to recapture Shandryholovo and Zarechnoye.\u201d\n\n\n\n\u201cThe enemy did not inflict significant losses on Russian troops, as the concentration of units of the West group of forces in the salient remained relatively low,\u201d Rybar added. \u201cHowever, later, the UAF deployed reserves to launch an offensive towards Zherebets in order to align the front along the water barrier and return it to the configuration of the end of 2025.\u201d\n\n\n\n\n\n\nrybar now saying the 144th division is still falling back. the 3rd corps is still advancing and destroying an entire army group as they move. this is historic. pic.twitter.com/2jOa8KR9oA\u2014 david D. (@secretsqrl123) September 22, 2026\n\n\n\n\n\nThough the battle is still in flux, Kudryashov said there are lessons the rest of the Ukrainian military should heed.\n\n\n\n\u201cWinning one battle is not yet winning the war,\u201d he said. \u201cThe enemy is learning too. He changes tactics, looks for weak spots and tries to scale what works for him.\u201d\n\n\n\n\u201cSo our task is to be faster, not only in physically moving forward but also in our ability to see, think, decide and put into practice what delivers results,\u201d the deputy commander avowed. \u201cAnd to do everything possible so that our soldiers pay the lowest possible price for every next kilometer of Ukrainian land.\u201d\n\n\n\nThe Latest\n\n\n\nOn the battlefield, in addition to the gains Ukraine has made near Lyman, it has also largely been able to hold off Russian advances across the front lines. Here are some key takeaways from the latest Institute for the Study of War assessment of frontline operations:\n\n\n\n\nSumy: Russian forces recently conducted an infiltration mission east of Sumy City, and they continue to conduct glide bomb strikes against frontline settlements in northern Sumy Oblast to set conditions for future offensives.\n\n\n\n\n\nKharkiv: Russian forces continued offensive operations in northern Kharkiv Oblast and in the Borova, Kupyansk and Velykyi Burluk directions on Sept. 21 and 22 but did not advance.\n\n\n\n\n\nDonetsk: Ukrainian forces reportedly continue counterattacks in the Lyman direction, including southeast of Lyman, as Russian forces are attempting to use redeployments to stabilize the area. Russian forces continued offensive operations east and southeast of Slovyansk near Rai-Oleksandrivka and toward Mykolaivka and Fedorivka Druha on Sept. 21 and 22 but did not advance. During this period, they also tried to advance in the Novopavlivka and Oleksandrivka directions but made no gains, as Ukrainian forces counterattacked in both areas.\n\n\n\n\n\nZaporizhia: Ukrainian forces recently advanced or maintained positions in western Zaporizhia Oblast.\n\n\n\n\n\nKherson: Neither Russian nor Ukrainian forces reported ground activity in the Kherson direction on September 22.\n\n\n\n\n\n\n\nRussian Offensive Campaign Assessment, September 22, 2026: The Russian Ministry of Defense (MoD) falsely claimed that Russian forces have encircled Dobropillya \u2014 an intensification of the Kremlin\u2019s cognitive warfare campaign alleging encirclements across various sectors of the\u2026 pic.twitter.com/yMoAcyVIme\u2014 Institute for the Study of War (@TheStudyofWar) September 23, 2026\n\n\n\n\n\nIn his speech to the U.N. General Assembly this afternoon, Ukrainian President Volodymyr Zelensky called for Russia to end its war and said it was paying a heavy price \u2014 and exacting a terrible toll \u2014 for little territorial gain.\n\n\n\n\u201cThis ridiculous and never-ending war with Ukraine must be ended,\u201d the Ukrainian leader urged. \u201cI do not know a single world leader who would say otherwise. I do not know anyone who is openly for this war, except one man.\u201d\n\n\n\nHe was referring to Russian President Vladimir Putin.\n\n\n\n\u201cLadies and gentlemen, for almost five years now, Russian generals have been trying to carry out Putin\u2019s crazy order to seize our eastern land, the Donetsk region,\u201d Zelensky continued. \u201cAnd just this year, from January through August, the Russian army lost 248,964 people on the battlefield in Ukraine in eight months. Twenty-one countries in the world have smaller populations\u2026 than the number of Russian troops lost in just eight months.\u201d\n\n\n\n\n\t\n\t\t\n\t\t\t\t'Patient Zero' Putin, Russia-Ukraine war & Trump: Zelensky addresses UN\t\t\t\n\t\t\n\t\t\n\t\t\t\n\t\t\t\n\t\t\n\t\n\t\n\n\n\n\n\n\u201cIt\u2019s madness, but they still keep going there to die because that is what Putin wants,\u201d Zelensky suggested. \u201cAfter losing so many people, Russia managed to capture just over 1,000 square kilometers of our land this year, and we have already liberated a significant part of it. Russia is a country that already has 17 million square kilometers of its own land without any Ukrainian territory, by the way. So to add another 1,000 square kilometers, Putin is paying with 248 people for every kilometer. Does anyone still think that he is reasonable? And moderate?\u201d\n\n\n\n\u201cRussia\u2019s leader, Patient Zero, the man from whom this war began and spread into the world, becoming the largest war in Europe since World War II, will inevitably leave this war,\u201d Zelensky proffered. \u201cBut the longer Putin is able to wage war, the more evil he will leave behind in this world. Today, nothing in war works the same way it did, by the way, in 2022, except the courage of people.\u201d\n\n\n\nRussian missile and drone barrages have \u201ccaused damage, but they didn\u2019t break us,\u201d the president proclaimed. \u201cWe build our defense. What is really difficult for us now is Russian ballistic missiles and their new jet-powered Shaheds \u2014 Iranian technologies.\u201d\n\n\n\nResidential buildings stand against the backdrop of smoke from a Russian attack on Kyiv. (Photo by Bohdan Diev/Global Images Ukraine via Getty Images) Tatyana Kudel\u2019s\u2019ka\n\n\n\n\u201cJust imagine this: since the beginning of this year, Russia has already used more than 2,100 missiles of different types again against us, against Ukraine, our people and our children,\u201d Zelensky stated. \u201cMore than 950 of them were ballistic missiles. In eight months of this year, Russia used 63,000 attack drones of different types against Ukraine, our people, and more than 7,700 of them were jet-powered Shaheds, truly destructive and very dangerous weapons. Just think about it. The Russians launch jet-powered Shaheds every hour, every hour, against our cities, our economy, our infrastructure. Our combat aircraft are fighting them 24/7, and this is part of Russia\u2019s strategy to create a new threat every hour, to make life harder for the economy and to disrupt people\u2019s lives, and to stop children from being able to study, to study at school.\u201d\n\n\n\nSpeaking at the Sixth Summit of the International Crimea Platform in New York on Wednesday, Zelensky said the return of Crimea is a condition for any return to normal relations with Russia.\n\n\n\n\u201cDisrespect for international law began in 2014, when Russia entered Crimea,\u201d the Ukrainian leader stated. \u201cThere can be no full return to normality without Crimea, the restoration of security, the protection of people and lives, the release of prisoners held by Russia, and a return to the fundamental principles of international law. Territorial integrity matters, state sovereignty matters, and human lives matter. And Russia must learn this.\u201d\n\n\n\n\n\t\n\t\t\n\t\t\t\t\u0423\u0447\u0430\u0441\u0442\u044c \u0412\u043e\u043b\u043e\u0434\u0438\u043c\u0438\u0440\u0430 \u0417\u0435\u043b\u0435\u043d\u0441\u044c\u043a\u043e\u0433\u043e \u0432 \u0448\u043e\u0441\u0442\u043e\u043c\u0443 \u0441\u0430\u043c\u0456\u0442\u0456 \u043c\u0456\u0436\u043d\u0430\u0440\u043e\u0434\u043d\u043e\u0457 \u041a\u0440\u0438\u043c\u0441\u044c\u043a\u043e\u0457 \u043f\u043b\u0430\u0442\u0444\u043e\u0440\u043c\u0438\t\t\t\n\t\t\n\t\t\n\t\t\t\n\t\t\t\n\t\t\n\t\n\t\n\n\n\n\n\nTuesday, Zelensky met with U.S. President Donald Trump.\n\n\n\nAmong the topics of their three-hour meeting were a path to end the war and a renewed discussion about the licensing of Patriot air defense interceptors so they can be built in Ukraine. The country is struggling to defend against Russian ballistic missiles because of the dearth of these munitions.\n\n\n\n\u201cJust had a positive and productive meeting with President Trump on the sidelines of the UN General Assembly,\u201d the Ukrainian leader stated on X. \u201cBoth the United States and Ukraine want this senseless Russian war to end before winter. We discussed possible de-escalation steps that could pave the way to diplomacy.\u201d\n\n\n\n\u201cI am grateful that, in parallel with this, our teams continue to work on launching the production of Patriot interceptor missiles in Ukraine,\u201d Zelensky noted. \u201cThis is exactly what will help protect lives if Russia rejects negotiations and continues to rely on ballistic terror against our people this winter and beyond. We also discussed other bilateral and multilateral issues, including the winter air defense package for Ukraine. Thank you to President Trump, his team, and all the American people for their support.\u201d\n\n\n\n\n\n\nI just had a positive and productive meeting with President Trump @POTUS at UNGA. Both the U.S. and Ukraine want to see this senseless Russian war ended before winter. We discussed potential de-escalatory steps that can open up the way to diplomacy.

If you would have come in at the end, we would have had an answer. But we\u2019ll be talking about that. I mean, we talk about it all the time. Very capable people, really amazingly capable people.\u201d\n\n\n\nThis isn\u2019t the first time the two leaders have talked about a Patriot licensing deal. The issue came up back in July. As we noted at the time, such a deal faces big challenges.\n\n\n\nFirst of all, it could face bureaucratic and regulatory hurdles, like getting congressional approval. Major security concerns exist, not just by having license production of a very sensitive weapon in Ukraine but also having to do with whatever facility will perform the work, which would become a top target for Russia. Even if they got the clearance to move forward, delivery of new weapons will still take years due to the time it takes to build the facility and to source long-lead components.\n\n\n\nEven Lockheed Martin, one of the world\u2019s biggest arms makers, currently produces only about 650 PAC-3 MSE interceptors a year, or just shy of two per day. However, under a contract with the Pentagon inked in January, Lockheed is committed to boosting Patriot PAC-3 MSE annual production to 2,000 in the years to come.\n\n\n\nYou can read more about the headwinds a Patriot licensing deal would face, even if it were to come to fruition, in our initial story here.\n\n\n\nA Patriot interceptor.

General Assembly meeting, strikes by both sides continued.\n\n\n\n\u201cAt least 16 people were killed and 59 others injured in Russian attacks across Ukraine over the past day, as Russia launched several waves of ballistic missiles at Kyiv overnight,\u201d the Kyiv Independent reported, citing local authorities.\n\n\n\n\u201cTwo people were killed and eight others injured in Kyiv, where Russian ballistic missiles struck the capital in three waves overnight,\u201d the publication added. \u201cResidential buildings, a maternity hospital, energy, and logistics infrastructure were among the sites damaged, according to President Volodymyr Zelensky.\u201d\n\n\n\n\u201cRussia launched 282 attack drones of various types overnight, including jet-powered drones, as well as Zircon anti-ship missiles and Iskander-M, S-400, and KN-23 ballistic missiles,\u201d the news outlet stated, citing the Ukrainian Air Force. \u201cUkrainian air defenses shot down 227 aerial targets, including 219 drones, four Zircon missiles, three ballistic missiles, and one Banderol munition. Strikes were recorded at 13 locations, while debris from downed targets fell at 10 locations.\u201d\n\n\n\n\n\n\nA difficult night for Ukraine as Russia continued attacking our civilians, launching a ballistic missile attack on Kyiv, and attacking Kyiv and other Ukrainian regions with drones.The air raid alert in Kyiv was turned on at 3:28 a.m. and hasn't turned off since.\u25aa\ufe0fIn Kyiv, two\u2026 https://t.co/l1Vr7AMH5o pic.twitter.com/giT5FjWq80\u2014 Anton Gerashchenko (@Gerashchenko_en) September 24, 2026\n\n\n\n\n\nUkraine\u2019s strikes on Russian energy infrastructure continued.\n\n\n\n\u201cOver the past 24 hours, two oil refineries were hit \u2013 one in Bashkortostan and one in the Samara region.

While many systems might not need this fix, some of the lower-end drones might.\n\n\n\nUkraine is testing and scaling this technology as part of a layered navigation system designed to keep drones autonomous in heavily jammed environments.\n\n\n\n\u201cThe concept is quite simple,\u201d the BBC wrote. \u201cIf the enemy jams the signal coming from above\u2014specifically from GNSS (Global Navigation Satellite System) satellites, which determine the precise coordinates, speed, and time of any object on Earth\u2014then specific points must be created to provide that same signal from below.\u201d\n\n\n\nThe idea is to guide the drones by triangulating their location.\n\n\n\n\u201cTo achieve this, special small devices\u2014radio beacons\u2014are either installed on the ground or air-dropped across a specific area. Their coordinates are known; thus, when a drone flies through the area, it receives coordinate data and signal transmission timing from several beacons. From there, it is a matter of basic geometry: the UAV calculates its own spatial position using data on the distance to the beacon and its altitude above the ground.\u201d\n\n\n\n\n\n\nGPS can be jammed. Ukrainian drones still need to fly.A new beacon network is helping solve that problem.Small radio beacons placed on the ground allow drones to navigate without GNSS or a constant communications link \u2014 including missions deep inside russia.Ukraine is now\u2026\u2014 7th Corps of AAF (@7corpsDSHV) September 23, 2026\n\n\n\n\n\nIn the age of robots, uncrewed ground vehicles (UGVs) are playing a larger role in combat.
