紅幡鐵甲漫過山脊的行軍陣

A grand march of three thousand Red Banner troops, rendered in a fierce, menacing Chinese aesthetic — every soldier wearing an iron mask modeled after wrathful Asura and Rakshasa faces. The army is clearly divided into cavalry, infantry, heavy armored riders, and command units, moving forward like an unstoppable tide of iron. Show the distinct formations first, then pull the frame back to reveal a packed mass of troops spreading across hills and mountains, banners thick enough to blot out the sun. From this wider view, even more columns and troop types should be surging in from every direction, building the oppressive feeling of storm clouds pressing down on a city about to fall.
