Create an anime-style, human-shaped medium-sized mech standing tall on a battlefield. The mech features heavy armor in a mix of army green and white, with angular, sleek plates detailed with red highlights and glowing parts. It holds a large, futuristic rifle in one hand, exuding power and readiness. The design should emphasize mechanical complexity, with visible joints, pistons, and advanced technology. Smoke, debris, and dynamic lighting surround the scene, giving the sense of an intense, ongoing battle. The lighting should highlight the mech's imposing stature, while the background has a war-torn landscape.
