Concrete Military Bunker Entrance Low-poly 3D model

This military bunker entrance 3D model features reinforced concrete construction with angular geometry typical of World War era designs. The entrance is set into a mound of terrain, with overgrown vegetation subtly surrounding the structure to enhance realism. Cracks, chipped concrete edges, and water stains are visible across the bunker surface, conveying decades of exposure to the elements. This model fits seamlessly into war-themed environments, military game levels, or post-apocalyptic landscapes, providing a solid environmental storytelling element.
