The chairman of the Joint Chiefs of Staff, Gen. Mark Milley, said Friday that the Russian casualty number was "significantly well over 100,000." In November, Milley had said that "well over" 100,000 Russians had been killed or wounded.
That number includes Russians who have been killed in action, have died from wounds, or who were wounded and have been taken off the battlefield. The number of injured is believed to be higher than the number killed, one source said.
