Russia has lost 87% of the ground forces it had on active duty before invading Ukraine and two-thirds of its tanks, a source familiar with a declassified U.S. intelligence assessment provided to CNN told CNN . Despite these heavy losses, Russian President Vladimir Putin is determined to move forward, the television channel commented, while US officials warned that Ukraine remains extremely vulnerable. The expected Ukrainian counteroffensive gained momentum in the fall and, according to American officials, Kiev is unlikely to achieve major successes in the coming months.
