I didn't know why it would be it just feelz wrong. So I googled some things. I guess this kinda fits my feelings of why it would be:
"The action must be necessary to achieve a legitimate military objective. If the retreating soldiers pose no immediate threat or if their destruction does not contribute significantly to the military objective, the use of force might be deemed unnecessary."
But ultimately I think it boils down to war being heinous and I don't like people dying especially by a voiceless, human less, robot RC device. Just feels dystopian.
They are soldiers carrying weapons in an active combat zone. It's ugly, but this is just war in the way civilians haven't been privy to, for hundreds of years. (I don't mean drones, I mean ambushes at night)
If the video had shown them stripping down, discarding weapons/gear and holding up hands to the drone, then maybe you have something to discuss.
The military objective is to reduce the enemies ability to wage war. Inflicting military casualties is a legitimate means to that end otherwise any and all weapon use would be a warcrime. Efficacy is not a concern in this regard. In fact ethically speaking, the precision drones allow is an improvement over almost all other weapons (even bullets miss and strike civilians hundreds of meters away).
By continuing to hold a weapon even retreating troops (which these 2 aren't doing in the clip ftr) maintain their status as an immediate threat which makes them fair game, and in the fog of war even throwing down a weapon isn't enough because they likely have a sidearm and/or grenades.
Nope, can't blame them. I'm assuming the Appalachian mountains would be Iraq 2.0 if America was ever invaded.
And yes I know these are people defending their own country, just kinda sucks that war is war and not pillow fights or some shit. Or politicians boxing in a ring
