The real irony is that those guys on the other side of the trench are the same. All just cannon fodder sent to die by faceless higher ups giving the orders, and will see none of the benefits even if they win.
Hmm if they extend some stuff like the running scene, this volume could end with end of arc 1 which is sucks because cliffhanger but no complain if the story become better.
Let's see though, I prefer it ends in beginning of arc 2
