A modern military rocket launcher vehicle mounted on a 6-wheeled truck chassis, semi-realistic style. The design should be functional and tactical, with visible missile tubes on the back, light armor plating, a reinforced cabin, and rugged off-road tires. It should not look cartoony or toy-like — aim for a balanced level of detail suitable for a 3D tactical strategy game. Stylized PBR textures with moderate wear and military green paint.
