A futuristic imperial guardsman soldier, heavily armored, wearing dark green flak armor with metallic shoulder plates, a rugged helmet with a built-in visor, a gas mask, and a long trench coat. The soldier holds a sci-fi laser rifle (lasgun) with glowing red energy cells. Pouches and gear attached to the belt and chest. Stylized like a grimdark military sci-fi universe, with realistic textures: scratched metal, worn cloth, and dirty boots. Cinematic lighting, neutral pose, game-ready topology.
