Russian President Vladimir Putin’s December 1 decree is likely a formal recognition of the Russian military’s current end strength and not an order to immediately increase the number of Russian military personnel. Putin signed a decree on December 1 increasing the official end strength of the Russian military from 2.039 million personnel to 2.209 million personnel and total Russian combat personnel from 1.15 million to 1.32 million. The increase of 170,000 Russian combat personnel between Putin’s previous August 25, 2022 decree and the December 1, 2023 decree is likely a formal acknowledgement of a net increase of 170,000 combat personnel between August 25, 2022, and December 1, 2023, and not a call to immediately increase the current number of combat personnel by an additional 170,000. Russian Security Council Deputy Chairperson Dmitry Medvedev claimed on November 9 that the Russian military has recruited 410,000 contract, volunteer, and conscripted military personnel since January 1, 2023, then later claimed on December 1 that the Russian military has recruited over 452,000 personnel since January 1, 2023.The Russian government announced in September 2022 that the Russian military would mobilize 300,000 personnel under Putin’s partial mobilization decree. NATO Secretary General Jens Stoltenberg stated on November 29 that Russian forces have suffered over 300,000 casualties (killed and wounded personnel) in Ukraine since the start of Russia’s full-scale invasion of Ukraine in February 2022.Ongoing widespread crypto-mobilization efforts (such as volunteer recruitment and the coercion of migrants into the Russian military), partial mobilization, the number of Russian personnel concluding military service, and Russian casualties in Ukraine plausibly account for a net 170,000-combat personnel increase between August 25, 2022, and December 1, 2023.[6] Putin’s December 1, 2023 decree is thus likely establishing 2.209 million personnel as the new official end strength rather than ordering a significant new increase in the total size of the Russian military.
