This is stated in the report of the Institute for the Study of War (ISW).
Analysts note that social media footage published on March 8 reportedly shows personnel of the 136th Motorized Rifle Brigade of the 58th Combined Arms Army of the Southern Military District appealing to the Russian military command for more artillery ammunition before they replace the 155th Naval Infantry Brigade of the Pacific Fleet near Vuhledar and conduct ground attacks in the area.
"The 155th Naval Infantry Brigade bore a significant proportion of the catastrophic losses that Russian forces suffered in their culminated three-week February offensive to capture Vuheldar and has reportedly been reconstituted at least seven times since the start of Russia’s invasion of Ukraine. Russian forces may be rotating in the 136th Motorized Rifle Brigade to replace a severely degraded formation in hopes of renewing offensives near Vuhledar, although this one-for-one replacement does not represent a Russian reinforcement of this effort," the Institute believes.
According to experts, the 136th Motorized Rifle Brigade is unlikely to achieve tactical advances near Vuhledar that the 155th Naval Infantry Brigade, 40th Naval Infantry Brigade, and other Russian formations failed to make following months of preparation to start offensives in this direction.
"The likely degradation of other units in the area, significant equipment losses, and the reported continued artillery constraints will likely prevent Russian forces from securing significant tactical gains if they decide to resume offensives in the area," ISW writes.
Analysts also believe that the internal dynamics within the Russian military may be driving the potential resumption of costly offensives near Vuhledar that promise little operational benefit.
Russian Defense Minister Sergei Shoigu ordered the commander of the Eastern Military District, Colonel General Rustam Muradov, to take Vuhledar at any cost. This is to reduce criticism in the Russian Defense Ministry about the lack of progress and significant losses in the Vuhledar area.
The Institute for the Study of War reminded that Shoigu recently visited Muradov in western Donetsk Oblast likely to assess the viability of the Vuhledar offensive as well as Muradov’s continued role as a commander.
“Muradov would need new manpower and equipment reserves to follow through on Shoigu’s reported instructions, and the one-for-one replacement of the 155th Naval Infantry Brigade by the 136th Motorized Rifle Brigade does not represent a notable fraction of the reinforcements likely required. It is still not clear if Shoigu has decided to provide Muradov with the necessary resources to resume offensives, but Muradov may decide that he needs to resume offensive operations regardless to demonstrate his competence as EMD commander,” analysts say.
ISW assesses that Russian forces would need to advance upwards of 24km from the current frontlines around Vuhledar for this offensive to support operations elsewhere in Donetsk Oblast, a rate of advance that Russian forces have not achieved since the first months of the full-scale invasion of Ukraine.
"The resumption of costly offensives around Vuhledar would be a misallocation of already degraded forces to an increasingly nonsensical operational effort, but Muradov’s personal motivations may cause Russian forces in the area to resume these operations nonetheless," the experts added.
On March 8, Petro Andriushchenko, an adviser to the mayor of Mariupol, told Espreso that the invaders are using Mariupol and the Mariupol district as a logistics base and are deploying T-80 and T-72 tanks to the Vuhledar area.
