Russia is struggling to train reservists called up to fight in Ukraine, or find officers to lead new units, following Moscow's partial mobilisation, the Ministry of Defence (MOD) has said.
Russia's partial mobilisation, announced last month, has endured a number of problems in its first week and, in an update on Twitter, the MOD said Vladimir Putin's "unusually rapid acknowledgement of problems highlights the dysfunction of the mobilisation over its first week".
“As drafted reservists continue to assemble at tented transit camps, Russian officials are likely struggling to provide training and in finding officers to lead new units," the MOD tweeted.
When addressing the problems, the Russian president said, "a lot of questions are being raised during this mobilisation campaign", adding Russia should "promptly correct" mistakes and "not repeat them".
However, the MOD said in the update that "local officials are likely unclear on the exact scope and legal rationale of the campaign".
They also said Moscow has "almost certainly drafted some personnel who are outside the definitions claimed by Putin and the Ministry of Defence".
Watch: Russian army desperately short of the basics.
It comes after video surfaced on social media seemingly showing Russian recruits being told to buy most of their own kit, with the trainer telling them that the uniform is all that is provided by the military.
It is impossible to verify if this footage is genuine, but if it is, it showcases a Russian army desperately short of the basics – including battlefield medical supplies.
Over the weekend, the UK's Defence Secretary said Putin is "highly unlikely" to use nuclear weapons in the Ukraine conflict, but he is not acting in a "rational" way.
Ben Wallace said Mr Putin "was given a very clear sense what is acceptable and unacceptable" in meetings with the Indian and Chinese leaderships.
