Over 200,000 people have already been drafted into Russia's armed forces since President Vladimir Putin ordered a partial mobilisation two weeks ago, Defence Minister Sergei Shoigu said on Tuesday.
Shoigu had announced that he planned to enlist 300,000 men with previous military experience to bolster Russia's invasion of Ukraine, where it has suffered a series of defeats in recent weeks.
However, the official decree did not include a figure, and officials are keen to allay public fears that the actual number could be higher, as even pro-Kremlin figures voice concern that people are being recruited indiscriminately.
Reports have surfaced of men with no military experience or past draft age receiving call-up papers, adding to outrage that has reignited dormant - and banned - anti-war demonstrations.
