Western officials have told the BBC that North Korean troops have already suffered nearly 40% casualties in the fighting in Russia's western Kursk region, in just three months.

It will mostly be missile and artillery troops who typically operate hundreds of tubed and rocket artillery systems as well as the KN-23 short-range ballistic missiles Pyongyang has already provided Moscow,

The report highlights that North Korean soldiers have developed unique battlefield tactics, such as using a soldier as bait to shoot down drones or detonating grenades, holding it under the neck with one hand on the pin when the Ukrainian military approaches to avoid capture when severely wounded.

The unprecedented loss of life in a foreign conflict means that the war in Ukraine could be the Kim regime’s most significant test since the 1990s famine.

Ukraine’s president released a video of the two soldiers being interrogated, revealing they knew little about the war they were sent to fight in.

Ukrainian President Volodymyr Zelenskyy said he’s willing to hand over the soldiers to North Korea, if Kim Jong Un arranges for an exchange with Ukrainian prisoners of war in Russia.

Ukraine President Volodymyr Zelenskyy said this month that as many as 4,000 North Korean troops have been killed or wounded in recent weeks, with only two captured alive. Both men were wounded and transferred to custody in Kyiv, where Zelenskyy said they are being interrogated and treated for their injuries.
