During surrender russian soldier managed to throw a grenade that didn't go off

Perfidy

Also known as a war crime.

You don't do shit like this so that the enemy will accept your surrender. If they can't trust you not to attack, they'll just shoot you the moment your arms are in the air.

Wellt, it did go off. But luckily the idiot threw a smoke grenade instead of an explosive one.

Lucky ukranians. Wonder what the Russian oldiers are being told, if they're doing this sort of this. During world war 2, Japanese soldier were told that they be horrendously killed, including women and children. So many felt like the decision was between suicide and tortuous murder.
