The The Saga of Tanya the Evil, Vol. 5 (manga)

Winter is roughly two months out. The time limit has been set. But the Empire's military leaders are fiercely divided on what to do. Should they conduct aggressive offensives in hopes of a break through, or should they weather the winter and use that as a chance to reorganize, restructuring the lines of battle? In the end, they decided that while they gather supplies for a theoretical offensive, they would conduct an investigation to collect intelligence. Naturally, Tanya's Salamander Unit was the first candidate for the mission. Should they push ahead, or should they hold their ground? There's no time to hesitate. As the hellish conditions worsen, the war shows no sign of slowing down or becoming any less brutal. Everyone has no choice but keep what they hold dear close to their hearts as they march ever onwards toward the battlefield. Everything for the sake of the motherland, for the fatherland.
