Create an ultra-realistic 3D model of an anthropomorphic mouse in a T-Pose, barefoot, with 5 proportional fingers and toes, rigged for Unreal Engine. The model features soft gray-brown fur, large pink translucent ears, expressive dark eyes, and a small pink nose. The mouse wears detailed military armor: a Green helmet, patches, rounded shoulder pads, segmented arm/leg guards, and a practical backpack. Ensure 4K texture realism, balanced lighting, and a neutral background.
