Design a special forces soldier character with the following features: a man with olive-brown skin tone and a thick, well-groomed beard. He wears a modern tactical helmet equipped with night vision goggles lifted above his forehead. His expression is serious and determined, reflecting combat experience. He's dressed in a high-tech camouflage uniform suitable for special operations, with multiple pockets and tactical accessories. He wears a bulletproof vest with additional equipment. In his hands, he holds an advanced assault rifle. The design should convey strength, professionalism, and the elite nature of special forces, emphasizing his readiness for night missions or low-visibility conditions.
