The International Standard Warning Code is a universal system used by the various militaries of the world to alert pilots of the rapidly changing circumstances on the battlefield. Thanks to the IR system embedded in fortified suits, these codes are projected directly into the pilot's view. Pilots can turn the various warnings and their associated sounds off with a manual override located in their cockpit.
