North Korean soldiers use dangerous tactics in Russia.

North Korean soldiers in Russia are using brutal tactics, including detonating grenades to avoid capture and using other soldiers as decoys for drones. About 12,000 soldiers have been sent to Russia, and reports indicate that around 4,000 have been killed or injured. North Korean soldiers write oaths of loyalty to Kim Jong Un and use more modern military equipment. Ukrainian forces point out that these soldiers are unprepared for modern combat but are resilient.
