The video contains fairly standard recommendations: drop weapons, indicate a desire to surrender with a white flag or cloth, etc.
Separately, this video emphasizes that if soldiers first demonstrate their intention to surrender, and then open fire, this is interpreted by international law as a war crime, treachery. And in this case, the deceiving soldiers are very likely to be destroyed.
The video does not explicitly state this, but it is clearly a reference to another video that first shows footage of the surrender of Russian soldiers. And then they are shown dead. What happened between this gluing is still unknown.
In Russia, this video caused an extremely angry reaction. Authorities at various levels demanded an international investigation into the incident. Ukraine opened a criminal case on the fact of a possible violation of the rights and customs of war. But the authorities immediately voiced the version, which is also contained in the video of the General Staff of the Armed Forces of Ukraine – apparently, the Russians imitated the surrender in order to attack the Ukrainian soldiers and were killed themselves.
