Russia continues to lose ground in Ukraine three years into war

 ISW:

Russian President Vladimir Putin ordered the unprovoked full-scale invasion of Ukraine three years ago on February 24, 2022. Ukraine has not been defeated or destroyed but remains resilient and innovative in the face of this unjustified Russian aggression. Putin launched his full-scale invasion of Ukraine in a failed attempt to seize Kyiv City, overthrow Ukraine's democratically elected government, and forcibly install a pro-Russian proxy government in three days. Ukrainian forces, supported by a coalition of allies including the United States and European partners, have since successfully pushed Russian forces out of northern Ukraine and liberated significant territory in southern and northeastern Ukraine. Ukrainian Commander-in-Chief General Oleksander Syrskyi reported on February 24 that Ukrainian forces have regained more than 50 percent of the territory that Russian forces have occupied since February 24, 2022.[1] ISW has observed confirmation that Ukrainian forces have regained 50.03 percent of the territory that Russian forces had seized since February 24, 2022. Russian forces have spent the last year making slow and incremental but steady advances in eastern Ukraine as a result of significant Russian manpower and materiel advantages and Russia's ability to leverage delays in Western aid to Ukraine. Ukrainian forces are using their technological advantages and integrating technological innovations with ground operations in order to slow Russian gains. Ukraine continues to improve and innovate its warfighting capabilities and is working to become self-sufficient in the long-term, but Western and international military support for Ukraine in the short- and medium-term remains crucial for Ukraine's ability to defend against Russian aggression. The defense of Ukraine and the preservation of Ukraine as an independent, sovereign, and democratic country capable of defending itself against Russia is a critical part of deterring broader Russian aggression against the West. The United States, Europe, and other Western allies must demonstrate commitment to Ukraine through timely and reliable military assistance, continue to enable Ukrainian forces to impose significant pressure on Russia, and force Putin to abandon his conquest of Ukraine and his wider ambitions in Europe in order to bring about sustainable peace.

Russia has accumulated unsustainable personnel and vehicle losses in the last three years since Russia's full-scale invasion on February 24, 2022. Ukrainian Commander-in-Chief General Oleksander Syrskyi reported on February 24 that Russian forces have lost over 10,100 tanks, 21,100 armored combat vehicles, and 23,300 artillery systems presumably destroyed and damaged in the three years of Russia's full-scale invasion.[2] The British International Institute for Strategic Studies (IISS) recently estimated that Russia had lost about 14,000 tanks, infantry fighting vehicles, and armored personnel carriers since February 2022.[3] (IISS's numbers likely differ from those from Syrskyi as IISS data likely only accounts for destroyed vehicles.) Syrskyi stated on February 24 that Russian forces have lost almost 870,000 personnel, including about 250,000 dead.[4] Russian opposition outlets Meduza and Mediazona published a joint report on February 24 wherein they used the Russian Register of Inheritance Cases (RND) to estimate that at least 160,000 to 165,000 Russian servicemembers have died in the past three years of the war.[5] Syrskyi previously reported that Russian forces suffered more than 434,000 casualties in 2024 alone, and Meduza and Mediazone estimated in February 2024 that Russia had lost at least 66,000 to 88,000 personnel during the first two years of the war — suggesting that Russian loses significantly increased in 2024.[6] ISW continues to assess that Russian forces have suffered vehicle and artillery system losses on the battlefield that are unsustainable in the medium- to long-term given the limitations of Russia's defense industrial capacity and Soviet-era weapons and equipment stocks, and that Russia's force generation apparatus is struggling to recruit enough soldiers to sustain Russia's current rate of offensive operations and loss rates.[7]

The Russian invasion of Ukraine continues to look like a mistake.   Russia's initial concern was that Ukraine would join NATO and the threat would be at their border.  But even without NATO forces, Ukraine has imposed significant casualties on Russia of both manpower and equipment.  Russia is now a much weaker conventional force as a result of the war it started.  Russian equipment losses include their modern tanks and armored vehicles as well as significant portions of their older equipment that they have had to throw into the fight.  While Russia does have a large population it will be difficult for it to replace the losses it has incurred in what looks like a losing effort against a second-rate power like Ukraine.
