A senior Ukrainian military official predicted that Russia will begin using mobilized personnel on the battlefield in Ukraine from April 1.
This is reported by the Institute for the Study of War (ISW).
On March 21, the spokesman for the Southern Defense Forces of Ukraine, Colonel Vladislav Voloshin, told the Ukrainian news agency "Interfax-Ukraine" that from April 1, Russia will begin to include in combat operations in Ukraine all mobilized personnel currently in Crimea.
Voloshin said that the mobilized personnel will replace wounded soldiers and replenish the ranks of The 810th Separate Marine Brigade of the Russian Black Sea Fleet, parts of which are currently operating in the Kursk direction and in the operational-tactical group "Crimea".
Russia is likely resorting to the deployment of mobilized personnel as Russian forces continue to suffer heavy losses on the battlefield while struggling to recruit enough new volunteers to replace the losses.
Voloshin added that the Russian military command plans to reorganize the 810th Separate Marine Brigade into a marine division, which would be the tenth new maneuver division formed by Russia since 2022.
The Russian military command recently reorganized the 155th Marine Brigade of the Pacific Fleet into the 55th Marine Division, and the 336th Marine Brigade of the Baltic Fleet fleet - in the 120th Marine Division, effective December 2025.
Ukrainian counterattacks in southern Ukraine continue to have an operational and strategic impact on Russian forces in the run-up to the offensive in the spring and summer of 2026.
Ukrainian forces recently advanced into the Kostyantynivka-Druzhkovka tactical zone.
Ukrainian forces have struck military facilities and oil infrastructure in Russia. Russian forces have launched 139 drones against Ukraine.
