The UK MoD shared the assessment at a time when reports are emerging that Russia is considering the deployment of about two million military reservists to Ukraine under new legislation. According to The Moscow Times, the amendments to the law are likely to be backed by the country's parliament.

While speaking on the law, Alexei Zhuravlev, deputy chairman of Russia’s parliamentary defence committee, said the force of two million reservists was “professionals in their field” but were currently being unused. “Until now, it has only been possible to use this potential during periods of martial law or mobilisation. We are engaged in very real and large-scale combat operations [in Ukraine,] but officially, war has not been declared,” he told Russian news outlet RTVI.
Apart from this, an additional amendment would authorise their deployment abroad. Andrei Kartapolov, head of the Russian parliament’s defence committee, said that Putin could choose to deploy the reservists in Ukraine’s north-eastern Sumy and Kharkiv regions, where Moscow has been attempting to take new ground.
