Russian casualties in Ukraine continue to pile up

ISW:

The Kremlin is continuing to suffer significant manpower losses to make tactical advances in western Donetsk Oblast at the expense of Russia's ongoing war effort and the medium-term viability of the Russian economy. The United Kingdom Ministry of Defense (UK MoD), citing data from the Ukrainian General Staff, reported on December 5 that the average daily Russian personnel casualties reached a new all-time high of 1,523 casualties per day in November 2024.[1] The UK MoD noted that Russian forces suffered just over 2,000 casualties in a single day for the first time on November 28, 2024. Russian forces suffered an estimated 45,690 total casualties throughout November 2024, and the UK MoD noted that November 2024 was the fifth consecutive month that Russian casualties increased. ISW has observed geolocated evidence to assess that Russian forces advanced at a rate of roughly 27.96 square kilometers per day and seized a total of 839 square kilometers in Ukraine and Kursk Oblast in November 2024. ISW previously reported that Russian forces suffered increased casualties in September and October 2024 as well and that Russian casualties totaled an estimated 80,110 troops in exchange for roughly 1,517 square kilometers of gains in Ukraine and Kursk Oblast in those two months.[2] Russian forces have thus suffered an estimated 125,800 casualties during a period of intensified offensive operations in September, October, and November 2024 in exchange for 2,356 square kilometers of gains. (Or approximately 53 Russian casualties per square kilometer of Ukrainian territory seized.)

Russia's constrained labor pool is likely unable to sustain this increased casualty rate in the medium-term, and continued Western military support for Ukraine remains vital to Ukraine's ability to inflict losses at this rate. US officials reportedly estimated in late October 2024 that Russia's current recruitment rate was between 25,000 and 30,000 new soldiers per month.[3] Ukrainian military observer Petro Chernyk stated on December 3 that the Russian Ministry of Defense (MoD) would have to increase its monthly recruitment rates from 40,000-42,000 recruits to 50,000 recruits in order to seize the remainder of Donetsk Oblast while maintaining their current casualty rate....

Without increasing their recruitment rate Russia will not be able to sustain its current operations in Ukraine.  It is already taking an unusual number of casualties and accomplishing little in terms of its goal of conquering Ukraine.  The war has already made Russia much less of a conventional threat to Europe.  I suspect that the US and its allies are already reevaluating the Russian threat.
