SCANNER-class Mjolnir

SCANNER-class Mjolnir is a variant of the MJOLNIR Powered Assault Armor (GEN2) utilized by SPARTAN-IVs.

Development history
It was manufactured by the Materials Group and tested at the Damascus Testing Facility on Chi Ceti IV. It was designed for the facilitation of search-and-rescue strike teams protecting ONI personnel from capture by Insurrection forces. The armor is widely recognized as the best Mjolnir suit available for high value target and hostage recovery operations. The helmet features several sensor capabilities and user-adjustable settings that are not yet compatible with standard VISR hardware.

Trivia

 * In Halo 4, Scanner is one of four helmet-only armor sets alongside the Locus, Deadeye, and Strider helmets.
 * It is an exclusive to both the Limited Edition and the stand-alone War Games Map Pass along with MJOLNIR Powered Assault Armor/Strider and the in-game Falcon Emblem.
 * Without the scope attachment, as shown in the concept art, the Scanner helmet would have born a strong resemblance to the Mark V version of the Commando variant helmet, more so than the GEN2 version.
 * In Halo 5: Guardians, the Scanner armor is the same as the Soldier armor
