As I said, a mannequin is a terrible human stand in, it doesn't realistically reflect the damage a human might have suffered in that situation. If you can't properly damage the structure enemy is hiding behind, your shrapnel is not going to harm the enemy, especially since they are not going to stand around like a mannequin.Because the target were the persons inside that "foxhole". You can clearly see the fragmentation damage on those mannequins.
That thing is basically just a flying hand grenade.
Or do you have a video, where a kamikaze fpv drone (anti-personnel) does your expected damage?
I do actually, a metric fuck ton of, but unfortunately reddit is broke at this moment. But you can see them on r/combatfootage if you want.
Also, you getting defensive every time someone criticizes something you share or disagrees with your view is really getting old mate. People can have different opinions, get over it.
