Relatives grieve over Ukrainian serviceman Chernikov Pavlo during his funeral at the Church of the Most Holy Apostles Peter and Paul on March 28, 2022 in Lviv, Ukraine. Mr. Pavlo was killed in the eastern part of Ukraine fighting against the Russian military. Since Russia’s Feb. 24 attack on Ukraine, estimated military casualties for both sides vary widely. As of March 12, Ukraine said that 1,300 of its soldiers had been killed, while the U.S. estimated between 2,000 and 4,000. The consensus of foreign governments is that Russian troop losses have been far greater, with NATO estimating yesterday that 7,000—15,000 soldiers had been killed in action, with thousands more wounded.
