Ukraine: ”Morale of North Korean troops is declining”... ”Fake casualty numbers reported to headquarters”

Ukraine claimed that North Korean troops deployed to Russia were generally demoralized and had drinking problems.
On the 2nd (local time) the GUR posted on social media, "The morale of North Korean soldiers is falling. They are responding to the Russian military's message that 'The participation of North Korean troops in the war with Ukraine is very important.'"
"They continue to be brainwashed by propaganda," the article said. It also said that there is a problem of "excessive drinking" among North Korean soldiers deployed to the country.
The GUR said, "The commander lied when reporting the actual number of North Korean soldiers killed and wounded to the advanced headquarters.
"Russian commanders are moving fresh North Korean troops to the front line to replenish losses and strengthen the front line," he said.
