Andrii Otchenash, a soldier of the 4th Rapid Reaction Brigade Rubizh of the National Guard of Ukraine, shared the information on Espreso TV.“The 4th Rapid Response Brigade holds one of the toughest sectors — the Lyman–Kupiansk direction — and destroys a large number of Russian troops every day. Currently, the Pokrovsk direction shows how and where the Russians will try to advance next, as a huge number of experienced and professional units have been thrown into the Lyman–Kupiansk sector to destroy Ukrainian logistics. And we must admit that they are achieving certain successes,” Otchenash noted.According to him, the Russian forces have begun to use armored vehicles in the Lyman–Kupiansk sector — a rather telling sign.“This shows that Russian forces are trying to advance as far as possible before the mud season begins and while it is still possible to use equipment. They report to their commanders, politicians, and figures like Putin that they have allegedly encircled Pokrovsk and Dobropillia — which is completely untrue. However, given the enormous losses they are suffering, they are not achieving their desired results. That’s 100% certain,” Otchenash emphasized.Since Monday, October 20, 133 combat engagements have been recorded on the Russian-Ukrainian front. In the Pokrovsk sector, the Defense Forces repelled 54 attacks.
