Russian President Vladimir Putin’s announcement of “partial mobilization” on September 21 reflected many problems Russia faces in its faltering invasion of Ukraine that Moscow is unlikely to be able to resolve in the coming months. Putin’s order to mobilize part of Russia’s “trained” reserve, that is, individuals who have completed their mandatory conscript service, will not generate significant usable Russian combat power for months. It may suffice to sustain the current levels of Russian military manpower in 2023 by offsetting Russian casualties, although even that is not yet clear. It will occur in deliberate phases, Russian Defense Minister Sergei Shoigu said in an interview on September 21, likely precluding any sudden influx of Russian forces that could dramatically shift the tide of the war. Russia’s partial mobilization will thus not deprive Ukraine of the opportunity to liberate more of its occupied territory into and through the winter.
