Gritty WWI Trench Warfare Scene

the prompt

Gritty, cinematic World War I trench warfare. Soldiers in WWI uniforms fire rifles from behind sandbags on a muddy, overcast battlefield, explosions erupting. A low-angle shot tracks two soldiers crawling desperately through deep mud and barbed wire, dodging gunfire, their faces grim and determined. The visual style is dark, desaturated, and realistic.
