**Extreme close-up, low angle ground-level shot. A pair of soldier's feet wearing worn-out traditional woven straw sandals (草鞋) and tight fabric leg wrappings (puttees) stepping forcefully into deep, viscous, rain-soaked mud.
Action: As the foot lands, dirty muddy water splashes upwards in slow motion, capturing the raw impact and power. The muscles in the calf tense up visibly. The pace is heavy but determined, marching forward against resistance.
Environment: The ground is a chaotic mixture of wet mud, puddles, and scattered war debris (broken stones, rubble). Heavy rain is falling, creating ripples in the puddles.
Atmosphere & Style: 1940s historical documentary footage style. Black and white (monochrome). Heavy film grain, scratches, and dust overlays simulating old damaged film stock. High contrast lighting with harsh shadows. Handheld camera shake to add a sense of urgency and realism. A visual metaphor for resilience, strength, and an unbreakable spirit. Hyper-realistic texture, 4k resolution.**
