The Dread Squeaky Battalion

In a never-ending war fought with clanking steam-suits and brass howitzers, the most feared unit on the battlefield isn't the elite Iron Lancers or the Sky Admiral's fleet. It's Squad Seven. Their suits wheeze, leak oil, and squeak embarrassingly with every step. The military gave them obsolete junk so they'd fail basic training and get sent home. Instead, they accidentally win every battle through ridiculous improvisation.
When the High Command secretly plans to disband them by manufacturing a "heroic sacrifice" mission, Squad Seven must use their scrapyard genius to expose the conspiracy - and save the war from the adults who are doing it wrong.
