Russia lost 330 personnel, 14 tanks and 26 armored fighting vehicles (AFV) in one day, data provided by the Ukrainian military showed.
Combat losses among Russian personnel between the start of the invasion on Feb. 24 and Thursday numbered 61,330, according to the latest casualty report from the General Staff of the Armed Forces of Ukraine.
Russia also supposedly lost 2,449 tanks and 5,064 AFVs, among other pieces of military equipment, within the same period.
In its previous casualty report released Wednesday, the General Staff of the Armed Forces of Ukraine claimed Russia had lost 61,000 personnel, 2,435 tanks and 5,038 AFVs at the time.
Most of the recent losses were sustained in the directions of the cities of Kramatorsk, Avdiivka and Kryvyi Rih, according to the Ukrainian military.
About 5,937 Russian soldiers have died in Ukraine since Russia began its invasion, Russian Defense Minister Sergei Shoigu said on Sept. 21.
However, independent Russian media outlet Mediazona reported 6,756 Russian military deaths in the conflict as of Sept. 25.
The U.S. Under Secretary of Defense for Policy Colin Kahl estimated in August that Russia had lost up to 80,000 men.
Russian President Vladimir Putin announced troop mobilization in late September amid the reports of Russia’s growing casualties in the war.
The “partial mobilization,” the first such initiative in Russia since World War II, sought to call in up to 300,000 reservists, according to Shoigu.
Russian authorities may end up conscripting up to 1.2 million during the mobilization, Meduza previously reported, citing an unnamed source close to one of Russia’s federal ministries.
More than 200,000 people have already been drafted into Russia’s army since Putin made his announcement, Shoigu revealed Tuesday.
Despite its efforts, Russia is unlikely to gain significant military power this year just from mobilizing, according to the Institute for the Study of War (ISW).
“Putin will have to fix basic flaws in the Russian military personnel and equipment systems if mobilization is to have any significant impact even in the longer term,” the U.S.-based think tank said in a statement.
“His actions thus far suggest that he is far more concerned with rushing bodies to the battlefield than with addressing these fundamental flaws,” the ISW claimed.
