Visual Intelligenge System Reconnaisance. It's a data management system linked into a helmet's HUD. Current versions of it are very buggy, but they're useful to ID objects in poor lightning -friends, enemies, environment, and objects-.

[Granted, S-III try it first and they aren't even made yet on the year she's from, but we all know how Halo canon is with dates sometimes, and the mun needed another example of things to see with in the dark.]
