Why Should We Pick This Up?

Hello I'm actually not sure if the novel I'm specifying is here on the site. I forgot the title but I know it was a series back in Arcane Translations and it was one of the better war stories I enjoyed so it would be great if I could read it again. Oh and if the novel I'm specifying is here I would appreciate if the name was mentioned in the comments to this. Again to whoever translator is reading this, I sincerely apologize for the really vague title and synopsis.
