Ukraine has committed more forces to its counteroffensive in the southeast after nearly two months of slow progress, according to two US officials — a sign that they have identified potential weaknesses in Russian defensive lines to exploit.
The Ukrainian military still has additional combat power in reserve, but this is the “main bulk” of the forces committed to the counteroffensive, one official said.
The newly committed units had been held in reserve until now as other Ukrainian forces made slow, grinding progress against widespread Russian defensive lines and minefields while under threat of aerial assaults and artillery fire.
In the southeast, the Ukrainian counteroffensive has broken through some elements of Russian defensive lines, the official said, and the reserve units have come in to capitalize on the opportunity.
The New York Times was the first to report on the commitment of additional Ukrainian forces to the counteroffensive.
Ukrainian Defense Minister Oleksii Reznikov acknowledged over the weekend that the highly anticipated counteroffensive was behind schedule, but he insisted he was “not worried because it is going to plan.”
Reznikov said that Ukraine needs to use “soldiers, sappers, and deminers” to pick their way through Russian minefields, but that they were preparing the battlefield for the “real offensive movement.”
Even with the commitment of additional forces to the counteroffensive, Ukraine’s progress may not be immediate, since Russia has multiple layers of defensive lines which they’ve building and reinforcing for months.
Joint Chiefs Chair Gen. Mark Milley said last week that Russia had a “very complex defense in depth” across the front line in Ukraine, comparing it to trenches in World War I.
“They’ve got a very extensive security zone in-depth,” Milley said at a briefing following a virtual meeting of the Ukraine Defense Contact Group,” and then they’ve got at least two, perhaps even three main defensive belts.”
“What the Ukrainians have, though, is a significant amount of combat power not yet committed,” Milley said at the time.
On Wednesday, Deputy Defense Minister Hanna Maliar said that offensive operations along the southern front were “gradually advancing,” with similar, gradual progress also taking place further east in the area of Staromaiorsk.
Near the village of Robotyne, Ukraine’s 47th Brigade has been trying to break through heavily-mined Russian defensive lines, making use of US armored vehicles to attack enemy positions.
A member of the Russian-installed Zaporizhzhia military-civilian administration, Vladimir Rogov, wrote on Telegram on Wednesday that Ukrainian forces, backed by armored vehicles and tanks, had managed to “wedge in three sections of our first line of defense” near Robotyne.
Rogov said Russian forces were using their full arsenal, including aviation strikes, to push back against the Ukrainian units carrying out the assault, which he claimed were Western-equipped and trained.
“The fighters of these brigades have been trained abroad, and the brigades themselves are equipped with Western military equipment, including Leopard tanks and Bradley BMPs,” he wrote.”
The Russian-installed governor of the Zaporizhzhia region, Yevgeny Balitsky, also said a Ukrainian attack was underway.
Ukrainian officials have not publicly commented or confirmed this offensive.
