2022 Russian mobilization

On 21 September 2022, Russia declared that it was initiating a "partial mobilization" of military reservists to bolster the country's war effort against Ukraine. The announcement came after the Russian government's decision to conduct "annexation referendums" throughout occupied Ukraine—on behalf of the entirety of four Ukrainian regions that it only controlled in part: Donetsk, Luhansk, Kherson, and Zaporizhzhia.
