Visual Intelligence System, Reconnaissance
The Visual Intelligence System, Reconnaissance (VISR, pronounced "visor") is a proprietary integrated data management system used by UNSC personnel. It is incorporated into the helmets of Orbital Drop Shock Troopers and MJOLNIR GEN2, the latter of which features Version 4.0 of the suite.
VISR provides tactical data in real time as it is broadcast. It can link into UEG, CAA, and UNSC infrastructure systems at the local, national, and global network levels, administered on a need or rating basis. The version of VISR issued to ODSTs near the end of the Human-Covenant War allows the user to store and review up to 610MB of content relevant to the current or all mission objectives.
Among other functions, VISR also provides navigational data and highlights various points of interest in the operational area. As of ODST BIOS update A29.817941B.01 it also features light enhancement systems, raising the brightness of the surrounding area on the user's heads-up display during low-light operations. VISR's low-light vision enhancement also links with the user's neural interface to provide Friend or Foe designation by searching for IFF transponders on friendly or enemy personnel. Enemy and friendly personnel and matériel are highlighted with different colors. Friendly combatants are highlighted in green whereas enemy combatants are highlighted in red. Usable weapons, vehicles, and medical kits are highlighted in blue; other objects and structures are highlighted in orange; beacons and data terminals are highlighted in yellow.
VISR's core technology was originally developed for the MJOLNIR Powered Assault Armor, though the first VISR systems date back to the early 21st century, alternately bloating in complexity and paring down to bare-bones HUD management since then. VISR was field tested by Spartan-III Headhunters. Unlike the visual interface system developed for the Spartans, the ODST VISR requires no neural interface. With the introduction of MJOLNIR [GEN2], the VISR 4.0 suite is now utilized by Spartan-IVs. This version is more similar to previous incarnations of the MJOLNIR heads-up display than the one used by ODSTs, and the new BIOS firmware allows a modification to the suite with the Z-5080 Promethean vision module. As of 2558 the highest version number is 4.09, though several customized types are available to operators within the Spartan branch's Specialization wings.
The VISR database holds pertinent and relative information concerning battle to provide a distinct tactical advantage to the wearer. The database encompasses three main parameters situated in a carousel formation:
