Yeah, after Tanya used her miracle Type 95 and healed/reenergized everyone. Did you somehow miss out on chapter 42? This exact same phenomenon was done in exactly the place you're complaining about.@SpaceFootballKing
Neumann was previously impaled and self destructed during the retreat from the Rhine but was healthy enough to fly back and still remain in active duty
The 95 is indeed literally a miracle of god but that's an established thing in the story. Her wing wasn't shrugging off damage, her second in command was knocked out of the picture in Arene and still suffering from the wounds in the retreat.Ch 42 Pg 5:
"My fatigue... no, even my injuries from Arene are disappearing!"
"My body feels like it's on fire. It's like mana is flooding out of my body!"
"Neumann!! Are you alright!?"
"My wounds...!? The bleeding has stopped...!!"
And keep in mind: they lose. That's established from the beginning. In fact a huge interesting theme of this series is that Vianto is in some ways correct, that no single soldier, no matter how strong and blessed, no matter how many tactical battles they win, can triumph against overwhelming strategic odds. Indeed victory itself can be a trap, because war is only useful for political ends and military gains can be frittered away by political missteps. Failure can be non-linear. And technological advantages, while very valuable, are also very tenuous. You're seeing the Empire's high point right now, similar in spirit to our world's World Wars.
