Agricultural plant accident

In Chapter 18: God's Scenario, Suparna conducts an attack on a ABN agricultural plant in retribution for the Erbil L5 for which the ABN was blamed, the plant was unmanned and the members of the team take great care not to hit any civilians. However, reports come in right after that apparently there were 40 kindergartners on a school trip on the ground who were caught up in the bombing.

Rukhshana is in complete denial as she checked very carefully before attacking and Sujatha dismisses it as enemy propaganda. 

However in a later scene during an inquiry Suparna gets chastised by officers for causing civilian deaths in the attack on the plant, proving that it actually did happen,

So what actually happened? Even though Rukhshana and Sujatha have checked over and over again to make sure nobody was there, people were actually there, so have they made a mistake? Or perhaps they could not 'see' no matter how much they looked because the targets were hidden from them. It seems likely considering that the COU has special technology that makes things disappear from view of the Reaper's eye. 

Only two gauntlet knights that we know possess the ability to hide things from the view of the 8ms, and both of them are from the COU. Those are Momotake and Rukhshana, 

Momotake's Ability; 8ms stealth, allows him to hide himself and his allies from the view of the reapers eye, with the data provided by Aysha. We actually see this technology being used by Baibao when they were fighting against Grave Mole. In this scene Chloe is very confused because she is not able to see Baibao, even though they are in her range, almost as if they were invisible.

"Even though they should be close enough, i can't see them"

Rukhshana also has the ability : 8ms concealment, which allows her to disappear from view.

That's both of the ace COU teams that have a member who can make things invisible, what's more is that this ability doesn't appear anywhere else outside the COU. This is because invisibility is COU's Wisdom.

Wisdom 18721205, a golden triakis icosahedron is a wisdom named after the date of the disappearance of the crew of the Mary celeste, and it is also used to make Mario disappear, therefore the power of this wisdom is to make things disappear by hiding them from observation. The final piece of evidence is that the front face of the golden triakis icosahedron appears in the flag of the COU:

Wisdom are secret technology that each faction possesses to give them an edge in the war and COU's secret technology in invisibility, the ability to hide yourself and other things from the view of the reaper's eye.

Suparna checked the plant very carefully and they were unable to see anything, however people were there, that's because they were hidden from the view using wisdom 18721205.

Also Seshat who is the Egyptian Goddess of Wisdom amongst other things also has this ability, (Ghost)
