In addition to the North Korean army, the largest number of foreign mercenaries in the Russian army are Cubans, which is reported by Reuters. It says 1,000 to 5,000 Cubans are fighting for the Russian army in Ukraine, and this number has surged in recent weeks. The Russian army is increasingly recruiting Cuban mercenaries to fight.

Russian military expert Valery Shiryaev believes that the fighting in the past week shows that natural and artificial defensive barriers are no longer as important as they were in the early days of the war. The Russian army successfully forcibly crossed three rivers in a week: the Nitrius River northwest of Liman, the Veliky Zhelebets River northeast, and the Volchia River south of Novopavlivka. When the Russian army forcibly crossed these rivers, there was no fierce fighting. This shows that the defense line established by the Ukrainian army along the rivers is no longer an obstacle. The main reason is the shortage of Ukrainian soldiers.

In fact, when the Russian troops broke through the Volchya River, the Russian troops broke the "New Donbas" defensive line built by the Ukrainian army. This defensive line was built along the rivers and highlands, and had drone launch positions, these positions were good visibility, helped radio communications, and there were defensive works several kilometers behind the position, a layer overlayed.

On the ground battlefield, in the direction of Liman, the Russian army broke at least one-third of the Nitrius River defense line. At present, the Russian army is fighting for the city of New York, which is a large settlement on the west bank of the river, and the seizure here would benefit the Russian offensive on the west bank; at the same time, the Russian army also approached the northern outskirts of the city of Drobischev, in the northwest of the city is a forest connected with the city area, the Russian army is attacking here, taking the forest means attacking Drobischev. In the southeast of Liman, the Russian army seized back the railway station in the north of Yanburn, blocking the Russian army's direct passage to Liman.

In the nearby city of Sevilsk, the Russian army seized its southern village of Kuzminovka. Now, a village in the south of the city is still left to prevent the Russian advance. As long as the village of Zvanovka is taken, the Russian army can cut off another logistical line of Sevilsk and form the final siege, and the Russian army can even force the Ukrainian army to withdraw without even having to battle the city.

In the direction of Red Army City, the northern front has been reduced to hell. According to the military documentary report, due to the double blow of drones and artillery fire, almost neither side could evacuate the wounded. Burned vehicles and motorcycles were scattered on all roads leading to the front line. Due to the rain, all trenches accumulated. The water exceeded 20 centimeters. However, these did not affect the Russian army's offensive operations. As long as there is the cover of the forest belt, the Russian army will continue to attack. Although the forest belt has become very sparse, at least the losses are much smaller than attacking from an open field.

At present, the Russian army is launching an offensive along the line from Kucherovyar to Novo Toretkoye. Novo Toretkoye has been completely recaptured by the Russian army, and the Russian army has taken advantage of the opportunity to invade Vladimirovka. This basically means that the Ukrainian army's counterattack on the east bank of the Toretkoye River failed. The Ukrainian army has gathered a large number of troops and equipment in this small area. If the counterattack fails, the Ukrainian army may suffer backlash and fall into the encirclement of the Russian army. This is actually the most intense fighting on the northern line. All the other front lines of the Red Army City added together are not as fierce as the fierce fighting on the front line from Vladimirovka to Sofivka. This is purely infantry combat, and there is no equipment within a 10-kilometer radius. As long as there is equipment that enters this range, it will be immediately destroyed by drones. What the Russian army has invested here are "storm" troops, or cannon fodder troops.

On the West Bank, the Russian army captured the village of Vorne and captured it, which could force the Ukrainian army, which was counterattack along the line from Novi Shahovo to Merza Railway Station, to become more restrained. Especially the Ukrainian army in Novi Shahovo. The Russian army could threaten and advance behind it. Merza Railway Station was basically recaptured by the Ukrainian army, which was very unfavorable to the Russian troops on the northern line, and its logistics would be compressed by the Ukrainian army. The fighting in the urban area is still concentrated in several communities dominated by high-rise buildings in the southeast. Here, Russian troops used large-scale artillery to shell high-rise buildings to suppress Ukrainian firepower, and then sent ground commandos to advance.
