MJOLNIR Powered Assault Armor [GEN3]
From Halopedia, the Halo wiki
Early history and development
Although the MJOLNIR Powered Assault Armor (GEN2) meant a radical simplification of the Mjolnir platform, to the point it could be mass-produced, some in the Spartan Operations branch were dissatisfied with its minimal performance improvement over the old GEN1 systems. By that reason, the UNSC decided to manufacture the next generation of Mjolnir armors.
Around October 17, 2558, the Mark VII was used as the testbed for the GEN3 improvements, but it remained uncertain if manufacturers would adopt the standards and cost accounting by the Unified Earth Government.
On February 10, 2559, four months after the rise of Cortana and the Created, the Materials Group began to manufacture GEN3 armor. The Swords of Sanghelios have also become involved in the manufacture of some material for the GEN3 platform, such as the Anubis-class helmet, which is "grown" within Sangheili assembly forges. The GEN3 platform has also incorporated technology from other armor systems, as the GEN1 Mark V[B] platform and its variants have been made compatible with this newest iteration. Though this technology dates back to the Covenant War-era, it has been fully reconditioned and upgraded with newer and more optimized components, giving life to older tech at an integral time, and offering a new generation of Spartans the opportunity to take to the battlefield outfitted in the same style of armor that some of their own heroes once donned.
On October 7, 2559, John-117 and Blue Team were deployed on a covert mission to CASTLE Base using the GEN3 Mark VI armor. During a subsequent battle in New Mohács, Spartan IVs in GEN3 were deployed by drop pod.  Several months later on May 28, 2560, the armor was used by John-117 during a conflict on Installation 07.
Design and features
The conceptual design framework incorporates lessons from the MJOLNIR [GEN2] line of Mjolnir, while also using performance and higher levels of protection given by the MJOLNIR [GEN1] line of Mjolnir. Subsequently GEN3 weighs twice as much as GEN2 at 400 kilograms.
The armor features a survival mode that can keep the occupant alive for at least six months in the vacuum of space with no food, water, or other things vital to life aside from the suit's oxygen supply. After a burst of power was used by Fernando Esparza to bring John-117's armor out of survival mode, the armor's fusion reactor almost instantly recharged Echo 216's depleted batteries in return, restoring functioning to the Pelican's internal lights and systems. John later told the Weapon that the next thing that he remembered after getting thrown into space was waking up on the Pelican six months later, suggesting that he had been kept unconscious by the armor for the entire time.
At the very least, John-117's armor contains holographic emitters in the palm of the hand, allowing him to display an avatar of the Weapon over his hand, a feature not previously seen with his GEN1 and GEN2 suits while he was working with Cortana. The Weapon is able to transfer herself directly into systems by having her hologram walk off of the armor's hand and into the terminal in question.
John-117's armor displayed the ability to remotely link to the systems of Echo 216 and then activate the ship's autopilot at his request to fly them to a chosen destination.
Armor variants and upgrades
The following is a list of major variants of the GEN3 Mark VII and Mark VI platform.
The following is a list of armor accessories and modules compatible with GEN3 platform.
The armor system is built to support a variety of attachments and equipment which increases the level of combat effectiveness. Some of them have been reverse-engineered from Covenant technology.
In Discover Hope, while John-117's armor BIOS is activating, a line in the HUD reads "Preparing A.I. Intrusion countermeasures". This is likely to prevent AI intrusion following the rise of the Created.
