More details...the 1st "Da Vinci" Brigade and the 93rd Assault Brigade (Ukrainian) have joined the fight north of Pokrovsk, known as the "rabbit ears salient." The 1st is attacking from the north, the 93rd from the east, and the 1st Azov Corps units from the west. At this point the Russians still outnumber the Ukrainians engaged in this fight, and the Russians are on the defensive using prepared defenses and wooded areas to their advantage. So, while the Russian advance has been checked, that is, the Russians have dug in, stopped trying to advance, there is no way the Ukrans can dislodge the Russians...not with these numbers.
In other places the Russians are enjoying success along the eastern front. Being reported that the city of Toretsk has fallen, and the Russians have entered the central portion of Chasiv Yar. No way to sugarcoat it, the Putinites are winning along the eastern front where Putin has concentrated 250,000 fresh troops and has them focusing on specific targets (cities). The Ukrans have no choice but to leave some troops guarding the border and the front elsewhere and are unable to come close to matching the Russian buildups.
Note: the Azov Corps is designated the 1st Corps in the Ukranian army. I referred to it as the 3rd Corps because that was the initial designation, but later was changed to "1st Corps."
