Visual Intelligence System, Reconnaissance

"It's simple: If you see green, squad up. If you see red, shoot."

- Urk, Bungie.net.

The Visual Intelligence System, Reconnaissance, abbreviated to VISR, is an integrated data management system incorporated into the helmets of Orbital Drop Shock Troopers, able to perform a number of functions. It can link into UEG, CAA and UNSC infrastructure systems at the local, national, and global levels, administered on a need/rating basis, allowing the user to store and review up to 610MB of audio files, as well as street navigational data, receive real-time mission data, and other important functions. It also includes low-light vision enhancement systems (ODST BIOS A29.817941B.01), raising the brightness of the surrounding area on the users Heads-Up-Display and highlighting personnel or equipment of interest - "friendly" combatants are highlighted in green, "enemy" combatants are highlighted in red, usable equipment and weaponry are highlighted in blue, while other points of interest are highlighted in yellow.
