With the recent death toll of the Ukrainian army approaching 100 a day, the need to replenish troops for long-term warfare is being raised.
Ukrainian President Volodymyr Zelensky said this week that between 60 and 100 Ukrainian soldiers were killed in a single day, the Associated Press reported on the 5th.
This is significantly higher than the average daily death toll of less than 50 Americans in 1968, when the U.S. military suffered the greatest loss in the Vietnam War.
"This is one of the most important moments of the war, but it is not yet the pinnacle," said former Ukrainian Army Chief of Staff Viktor Muzenko, who feared that casualties could rise.
"This is the largest clash in Europe since World War II," he added.
The casualties are mainly in eastern Ukraine, where Russian forces have been focusing their offensive recently.
Ben Hodges, former commander of U.S. forces in Europe, said: "Russia is adopting a medieval war of attrition.
He also observed that "sacrifices of this scale will continue until the weapons promised by the West, including the United States, arrive in Ukraine and destroy Russian batteries."
Before the start of the war, the Ukrainian army had about 250,000 regular troops and was pushing for an increase of 100,000.
The number of casualties in this war is known to be much lower than that of the Russian army, but the recent increase in the number of casualties raises the need for replenishment.
