Design a detailed 3D render of a young military Captain in full tactical gear: helmet with NVGs, vest, camo uniform, and gloves. Armed with a sleek sniper rifle (scope, bipod, suppressor), the officer is in a dynamic crouched pose, scanning through the scope. Set in a rugged, war-torn environment like a desert or jungle, with dust, debris, and muted tones. Use dramatic lighting with sharp shadows to highlight gear details, creating a gritty, immersive modern military scene.
