At least this confusion conveys the tone of a city door-to-door battlefield.
Reading back, while it's clear that army underestimates the situation, some actions and words from Agatha are more clear. Also, since she was responsible for the "prisoners"...
Wait, I lost count of the tanks.
One was destroyed in the previous chapters.
Finke & Agatha deserted (2 tanks).
Dark-skin tank girl shot the bell tower to avenge her brother but still loyal to army.
Side to side with her there is a second tank, Bergen(?).
In the last pages Agatha and dark skin...
