Create a realistic image of a 30-year-old woman with sandy brown hair and darker eyebrows, featuring blue-green eyes. She should be wearing a sci-fi military uniform made from tough synthetic fabric, which consists of a structured jacket over a white shirt and pants, not a bodysuit. The jacket should be detailed, showcasing a modern design with a blend of colors, emphasizing functionality and style. Ensure her body proportions are realistic to reflect an athletic yet approachable appearance. Add subtle details like a belt with a small holster on the side of her pants, hinting at her role in a futuristic setting
