The UK intel said that Putin's new troops would suffer a lot in Ukraine.
The first wave of Russian conscripts arrived at military bases across the country, according to a Monday intelligence update from the Ministry of Defence.
The Russian military will provide low-level initial training to the soldiers, but will struggle to find military commanders to conduct the training because the majority have already been deployed in Ukraine.
Many of the drafted troops will deploy to the front line with minimal relevant preparation because of the lack of military trainers.
It said they are likely to suffer a high attrition rate.
Putin said last week that he would call up 300,000 people from Russia's military reserve. Those with combat experience will not be affected by the decree.
The announcement was seen as a sign of the failure of Russia's military in the country.
Some draftees don't go through military training before being sent to the front, according to a report from the general staff of the armed forces.
Despite their lack of training, Ukrainians are still worried about Putin.
A member of Ukraine's territorial defense forces said that it was bad news. The Russians will have a gun even if they don't have motivation.
Ukrainian President Volodymyr Zelenskyy called on Russian soldiers not to be involved in criminal activity.
It's Flee. Zelenskyy said to surrender to the Ukrainians at the first chance.
They are starting to realize that this is a question of their life. They should not die in this war. He said that one man wanted in a war.
