sending High Schoolers to war wasn't the best idea, as they all fought the powerful villains...

So many got hurt, until Bakugou pushed Deku out of the way, causing him to be impaired in the chest, as he fell onto the ground, a deep and bleeding wound in his chest.

So many others were also near killed, Todoroki, Ochako...

Deku saw all his friends bleeding in pain, his enraged self held off Shigiraki, as the class ran to all the fallen.
