In Russia, the crisis of loss perception will begin after 80,000 servicemen have been killed in Ukraine. As of today, more than 25,000 have already been killed.

Oleksiy Arestovich, advisor to the head of the Office of the President, wrote this on Facebook.

"According to one of the pre-war calculations, the crisis of loss perception in the Russian Federation will begin after 80,000 dead. There is still work to do," he noted.

British intelligence states that heavy losses in Ukraine are sustained by the most combat-ready Russian units, which will take a long time to replenish.
