MJOLNIR Powered Assault Armor (GEN2)

The MJOLNIR Powered Assault Armor [GEN2] is the second system-wide generation of the MJOLNIR Powered Assault Armor. The GEN2, which is lighter than the Marks IV through VI, is worn by SPARTAN-II and SPARTAN-IV supersoldiers. The armor's first known use was by Naomi-010 in early 2553. The armor was then later used in widespread by SPARTAN-IVs aboard the in July 2557.

Background
The GEN2 was developed by the Materials Group as a response to the SPARTAN-IV project. The armor incorporates new ad hoc modification systems which gives the armor the ability to use tactical packages, support upgrades, and armor abilities. The GEN2 is now produced by half a dozen manufacturers, both within the military and among private contractors. Like its GEN1 predecessors, it is backwards compatible with previous armor systems such as the Mark VI.

Various upgrades were made with the GEN2 that previous armor systems did not have.
 * Sprint module: Unlike previous armor systems, the GEN2 has a built-in sprint module that allows the user to run at faster speeds by overriding safety protocols, inspired by the version developed by Catherine-B320 of NOBLE Team.

The armor system is built to support a variety of attachments and equipment which allows it to utilize armor abilities.
 * Active camouflage emitter - The active camo ability allows the wearer to temporarily become cloaked for brief periods of time.
 * Hologram module - This component allows the user to create a holographic projection of themselves that can distract enemy fire.
 * Hard-light Shield - A shield made from hard light engineered from Forerunner technology.
 * Thruster pack - A booster pack used to propel the wearer forward.
 * Promethean vision - A visual enhancement that behaves similarly to sonar and thus allows the visualization of movement through solid objects.

Armor components

 * Energy shielding: A protective barrier that surrounds the armor and protects the user from harm.
 * Fusion reactor: The fusion reactor is the most essential part of the MJOLNIR system, as it provides power to all equipment on the MJOLNIR armor - the reactor is built into the suit and allows for nearly unlimited movement. The fusion reactor in all versions of the MJOLNIR armor are half the size of a normal fusion pack that conventional marines carry around.
 * Magnetic weapon holder strips: The MJOLNIR armor features very small, yet powerful magnets placed on the legs, waist, and back of the suit that are used to hold any equipment or any weapons with a magnetic property. The suit also contains a magnet system within its boots that allows its wearer to stay attached to a metal surface in zero G environments and can be toggled on or off by the wearer.
 * Power supply control unit: Manages the power supply of the armor.
 * MJOLNIR GEN2 BIOS: The basic input/output system, standard firmware interface to the GEN2.
 * VISR 4.0: Up to version 4.09, these visor installments are optimized and customized to facilitate specialized tasks.
 * Force-multiplying circuits: Allows the user greatly enhanced reflexes and strength, improving mobility and combat effectiveness in close quarters.
 * Motion Tracker: Shows movement of friendly and enemy units within the system's radius.

Trivia
The way the GEN2 Armor is equipped by UNSC Infinity's machinery onto a SPARTAN-IV is similar to the way the Iron Man Armor is equipped in the Marvel Cinematic Universe. It is also similar to the way Terran marines in the Starcraft universe receive their powered armor.
