Russia never really stopped mobilizing men. They started the mobilization back in autumn, then passed several reforms to allow them to keep mobilizing men in a less conspicuous way, like making the delivery of the mobilization letter electronic and without receipt, adding restrictions to those who don’t go the conscription office and other laws. All these were done in the winter and thousands of reports of electronic mobilization letters surfaced during these months on the internet. It’s a steady stream conscripts rather than big batches, but the result it’s the same.
