Powered exoskeleton

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
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. 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) Exoskeleton and the HRUNTING/YGGDRASIL Mark I were exoskeleton systems derived from the earlier prototypes from the exoskeleton program which predated MJOLNIR. 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.

RKD, an Earth think-tank, created the HAYABUSA project concurrently with MJOLNIR and while the two were developed separately, they share many characteristics, and are interchangeable to a degree. SPARTAN-III supersoldiers used Semi-Powered Infiltration armor which, despite lacking the strength- and speed-augmentation capabilities of MJOLNIR, provides effective active camouflage by means of photoreactive panels, allowing covert operations in enemy territory. The Forerunners developed combat armor suits known as combat skins, using a class system based on numbers, on which the MJOLNIR Mark V and Mark VI would be rated Class 2.
