ISIDOR-class Mjolnir, or Mk. IV/I, is a MJOLNIR Powered Assault Armor helmet variant, designed for the MJOLNIR Mark IV platform.^[1]

Overview

Design details

The Isidor helmet improves on the specifications of MJOLNIR Mark IV armor in every way.^[1] The helmet is compatible with Watershed Division's TAC/MOTHWORM attachment, which consists of hardware and software allowing the wearer to evaluate both UNSC and Covenant encampments, troop and vehicle dispositions, and local topography to generate strategic planning factors for sharing on the battle network.^[2]

Development history

The design of the Isidor helmet originated with technical schematics created by the Spartan-II combat engineers of Yellow Team, ultimately being developed by the Office of Naval Intelligence's Materials Group. However, resource shortages limited the production run of these helmets.^[1]
