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.
