Where are the thermal goggles in Metal Gear Solid

At the beginning of the game, after you ride the lift to the surface, enter the truck parked outside the facility. Inside, you acquire the SOCOM handgun. Enter the facility by whatever route you prefer. Inside the hangar, along the walkway, there is a room being watched over by a security camera. Normally, if you don't grab the SOCOM outside, it is here instead. The Thermal Goggles will be in its place.
