In recent days, the conflict between Russia and Ukraine has become increasingly tense. According to reliable information from many sources, the Russian Armed Forces (RFAF) have launched major military operations in the direction of Sumy and a major offensive operation may be imminent. Some Western media outlets claim that the RFAF has concentrated about 125,000 troops, targeting the Sumy region, with the intention of launching a "final offensive" there. This military move has attracted widespread international attention and made Ukraine feel like it is facing a formidable enemy.
In terms of military strategy, the Sumy region is of important geographical importance. It is located in the northeast of Ukraine, bordering Russia. It is one of Ukraine's key border defenses and a strategic location that is disputed by both sides; most importantly, Sumy serves as a northeastern shield for the capital Kiev. Once Russia successfully controls Sumy, it will not only further strengthen Russia's security in the border area, but also form a strong military deterrent against the northern part of Ukraine. It can even cut off Ukraine's land transport supply lines with some Western countries, greatly affecting Ukraine's military strategic layout. In order to guard against this powerful attack by the RFAF, Ukraine has taken urgent action. According to the Ukrainian Ministry of Defense , the Ukrainian Armed Forces (AFU) has urgently mobilized six reserve brigades to the Sumy region to protect this place. These six brigades are the elite force of the AFU, including mechanized infantry brigades, armored brigades and other armed forces, with strong combat capabilities. The AFU hopes that, with these initial six brigades, they will be able to build a solid defense line in the Sumy region and prevent a surprise attack by the RFAF. Ukraine's Deep State channel reported that the AFU has now begun actively building defensive fortifications in the border area of Sumy Oblast. They are taking advantage of the local terrain, digging trenches, erecting anti-tank obstacles, building bunkers, etc., trying to create a comprehensive, multi-level defense system. At the same time, the AFU also increased air and ground reconnaissance around the Sumy area, using reconnaissance UAVs, reconnaissance satellites and other means to closely monitor all movements of the RFAF, in order to take timely response measures.
In this impending war, the weapons and equipment of both sides have also become the focus of attention. The 125,000 troops assembled by the RFAF this time are equipped with a large number of advanced weapons and equipment. Among them, tanks include models such as the T-90 and T-80. These tanks have strong firepower and protection and can play an important role on the battlefield. In terms of artillery, the RFAF has advanced equipment such as the Tornado multiple launch rocket system, which has a long range and great power, and can provide extensive fire protection for the AFU's defense line. In addition, the RFAF also focuses on many advanced fighter jets and armed helicopters such as the Su-35 and Mi-28, to provide fire support and support for ground combat forces. On the AFU side, the country's six brigades deployed to the Sumy region are also equipped with some advanced weapons. As for tanks, the AFU equips some brigades with advanced tanks imported from Western countries, such as the German Leopard 2 tank, which also has outstanding combat performance. In terms of air defense weapons, it is reported that the AFU also deployed a number of long-range air defense missile systems, aimed at countering Russian air strikes. Although the AFU possesses these advanced weapons, there is still a certain gap in terms of quantity and overall combat effectiveness compared to the RFAF. In terms of the comparison of the two sides' troop strength, the RFAF, with 125,000 troops, has a clear advantage in numbers. This allows the RFAF to use more diverse tactics when attacking, such as attacking from multiple directions, alternating encirclement, deep penetration operations, etc.
However, the AFU's six brigades have relatively few troops and they may face the risk of dispersion and gaps in their defense lines. However, relying on a solid defense system and advanced weapons, the AFU is also confident that it can fiercely confront the Russian army in the Sumy region. The upcoming battle in the Sumy region will certainly have a major impact on the Russia-Ukraine conflict situation. If the RFAF can successfully break through the AFU defenses and take control of the Sumy region, this will greatly boost the RFAF's morale and further consolidate Russia's strategic advantage in the Russia-Ukraine conflict. For Ukraine, the defense of the Sumy region is of utmost importance. Once Sumy is lost, Ukraine's northeastern defense line will be in danger of collapsing, which will have an extremely detrimental impact on Ukraine's national security, as the RFAF will have the opportunity to approach the capital Kiev from the northeast. Fearing an attack by the RFAF on Sumy, the AFU is actively building up fortifications and defensive positions in the forests. This activity is noted in the Gnilitsky and Tokarevsky forests in the east of Sumy, as well as in the north - in the area of the villages of Ivolzhanskoye, Kiyanitsa and Khrapovshchina, and in the northwest - in the Banny Yar nature reserve and the Nikolskaya Dacha area near the village of Mogritsa.
AFU is trying to turn the forests in Sumy into "Serebryanskoye Forest 2.0", similar to the Serebryanskoye Forest in the west of Lugansk Oblast; by building fortifications, trenches, secret positions with multiple entrances and exits, as well as gun emplacements and bunkers. At present, the RFAF fighting in Yunakovka is about 8 km from the said area and about 9-10 km from Banny Yar. Based on this, it can be concluded that in the event of an attack on Sumy, the RFAF will pass through forests. But to the north and west of Sumy there are no particularly dense forests, like the Serebryanskoye forest west of Lugansk. (photo source Kyiv Post, TASS, Deep State).
