In its December 21 Russian offensive campaign assessment, the Washington-based Institute for the Study of War (ISW) notes that Russia's Defense Minister Sergei Shoigu told a Russian Ministry of Defense (MoD) Collegium in Moscow on December 21 that he proposes to increase the strength of the country's army to 1.5 million servicemen. ISW argues that Russia is "very unlikely to form such a large conventional force in a timeline that is relevant for Russia’s war in Ukraine," although it could form it along the Shoigu-described lines in the more distant future "if Russian President Vladimir Putin decides to fundamentally change Russia’s strategic resource allocation over the long run."
He proposed increasing the strength of the Russian Armed Forces to 1.5 million servicemen, including 695,000 contract servicemen (Shoigu said in spring 2021 that 380,000 Russians were contract servicemen), gradually increasing the age of conscription for military service from 18 to 21 years and raising the age limit for conscripts from 27 to 30 years. Shoigu did not specify a timeline for these measures.
