Several Spartans in powered exoskeletons: (L-R) the MJOLNIR Mark V, the MJOLNIR Mark VI, and the Mark II SPI armor.

A powered exoskeleton is a mobile machine consisting primarily of a skeleton-like framework worn by a person and a power supply that supplies at least part of the activation energy for limb movement.

Description[edit]

Powered exoskeletons are designed to physically assist and, in many cases, protect the wearer. They may be designed to assist and protect soldiers and construction workers, or to allow people to survive in other dangerous environments. A wide medical market exists for powered exoskeletons to provide mobility assistance for aged and infirm people. Other possibilities include rescue work, such as in collapsed buildings, in which the device might allow a rescue worker to lift heavy debris, while simultaneously protecting him from falling rubble.

The MJOLNIR Powered Assault Armor designed by Dr. Catherine Halsey is the most sophisticated UNSC powered armor project so far. As one of its main strengths, the MJOLNIR system eschews traditional mechanized joints in favor of a strength-enhancing layer of electroactive liquid crystal and provides a cybernetic link which boosts the wearer's reactions by a factor of five.[1] While it is the most successful UNSC powered armor project, MJOLNIR is by no means the only effort to physically augment soldiers in combat. The HRUNTING Mark III [B] Cyclops and the HRUNTING/YGGDRASIL Mark I were exoskeleton systems derived from earlier prototypes developed by exoskeleton programs which predated MJOLNIR.[2] Large-scale powered exoskeletons became more common in the years following the Human-Covenant War, with at least one model, the Mantis, seeing battlefield use.

The Semi-Powered Infiltration armor predominantly used by the Spartan-III supersoldiers provides modest physical enhancement[3] as well as a rudimentary active camouflage by means of photoreactive panels, allowing covert operations in enemy territory.[4] RKD, an Earth think-tank, created Project HAYABUSA concurrently with MJOLNIR and while the two were developed separately, they share many characteristics, and are interchangeable to a degree.[5]

In 2558, Michael Crespo wore an older early-war suit of ODST armor, which apparently had an exoskeleton installed in it. It was noted to be significantly less capable than MJOLNIR Powered Assault Armor.[6]

The Forerunners' personal armor offered powered support to some extent. For combat use, they also developed armor suits known as combat skins, using a class system based on numbers, on which the MJOLNIR Mark V[7] and Mark VI[8] would be rated Class 2.

Known powered exoskeletons[edit]

There are form fitting exoskeleton suits that act as armor, and there are larger exoskeletons that act as vehicles.

Armored suits[edit]

Forerunner[edit]

  • Personal armor - Body-assist armor worn by virtually all Forerunners in everyday life

Human[edit]

United Nations Space Command[edit]
Venezia[edit]
  • Goblinstrike - The Goblinstrike effort by Venezia is a powered exoskeleton project to manufacture armor for human mercenaries such as jannisaries.[15]
    • Boggart - The first result that didn't result in fatalities from design defects, BOGGART-class armor is considered a friendly face to Banished and independent Unggoy.[15]
  • Infractor - Infractor suits are built for use by infiltration units, assassins, and reconnaissance forces based on the power armor used by Brute Stalkers.[16] The armor features passive sensors on the armor's shoulder plates and the helmet also houses the most advanced netwar gear that Venezian engineers can use.[17][18]
  • Sovereign - Manufactured by New Tyne Armory, the Sovereign armor features holoprojectors, micro-gravity shock dampeners on the armor's knee pads, and it integrates a Proselytization network on its chestplate.
  • Taskmaster - The Taskmaster armor is provided by Venezian power brokers for use with Banished Janissary mercenary commanders.[19] The helmet is compatible with the Blue Cornet attachment which uses repurposed Covenant parts and pirated UNSC firmware, with the unique Venezian design "glue" that creates a compact and secure comm uplink, back-doors aside.[20]
Banished[edit]

The Banished created several variants of armor typically for Janissary mercenaries that is compatible with MJOLNIR Powered Assault Armor.

  • Agitator - The Agitator helmets are compatible with any Mjolnir chassis, even those disabled by UNSC security locks.[21] The helmet is also compatible with the Shock-Treated Visor attachment.[22]
  • Assailer - Used by human janissaries allied with the Banished taking on front-line roles.[23]
  • Conqueror - The Conqueror helmet was manufactured by the Banished for use with Venezian janissaries using fusion of Covenant and UNSC technologies.[24] It is compatible with the Red Cornet attachment, a Banished equivalent of a UNSC Command Network Module used by Venezian janissaries and liasons.[25]
  • Cutthroat - Created as a collaboration between humans and Kig-Yar.[26] It is compatible with the Evil Eye attachment, which shares resemblance to the Kig-Yar targeting headgear.[27]
  • Renegade - The Renegade armor was developed by Venezian engineers and manufactured by the Banished. The Packleader Cornet attachment functions as a mark of rank and a hardened uplink module.[28]
