It's because killing unarmed soldiers during war is not a war crime.

Rule 3. All members of the armed forces of a party to the conflict are combatants, except medical and religious personnel.

Rule 47. Attacking persons who are recognized as hors de combat is prohibited. A person hors de combat is: (a) anyone who is in the power of an adverse party; (b) anyone who is defenceless because of unconsciousness, shipwreck, wounds or sickness; or (c) anyone who clearly expresses an intention to surrender; provided he or she abstains from any hostile act and does not attempt to escape

A surprise drone attack on any Russian combatant that isn't a medic or chaplain is "lawful", even if they aren't holding a weapon at the time.

Pretty sure I've seen some that fall under Rule 47.

There’s regularly uploaded footage of clearly surrendering soldiers directed towards a safe zone to give up. Propaganda is propaganda, but it happens more often than we might think.

Glad to hear it.

I wonder if some "Surrendering to a Drone" protocol couldn't be codified under the Geneva Convention EG "Visibly disassemble your gun, throw the bits in several directions" etc.
