The Nations Mobilize

The nations mobilize as the five great villages convert their alliance into an army. The episode is the war's muster — divisions assembled across village lines, old enemies issued matching headbands, the Allied Shinobi Forces organized under Gaara's supreme command. The scale of the coming conflict becomes concrete: tens of thousands of shinobi against the Akatsuki's Zetsu legions and reanimated dead. It's the canon arc's pivot to military epic, the world's forces marshaled for the apocalyptic war Tobi declared at the summit.
