All-purpose goggle, engineered by Hal Emmerich. Combines ENVG (Enhanced Night Vision Goggle) light amplification and thermal goggle capabilities with binocular functionality. When heavy artillery such as tanks enter the field of view, it displays their specifications and armaments. It also takes in body temperature, heart rate, and sweat secretion volume of soldiers in sight and calculates the physical and emotional state of each. While aiming a weapon, it visualizes the user's point of focus and projects a crosshair overlay. Enemy footprints can also be clearly detected using the goggle's night vision feature. Old Snake's model also acts as a corrective lens for farsightedness.
