RECON-class Mjolnir

RECON-class Mjolnir, also designated as the MJOLNIR Powered Assault Armor/R variant, is a stealth-oriented variant of the MJOLNIR Powered Assault Armor that was originally commissioned by the Office of Naval Intelligence and developed by the Materials Group, with the GEN2 version being manufactured by the Imbrium Machine Complex.

Specifications
The visor used was the B5D-R/Optics Suite.

There is also a non-Mjolnir version of the Recon variant used by ONI, the ODST S-1/ONI Recon BDU.

Development history
A prototype was created prior to the Fall of Reach concurrently with the Mark VI Prototype. Like the Mark VI Prototype, the armor underwent field tests to improve the final model. Before being finalized Recon was already shown to reduce armor silhouettes without decreasing survivability.

The Recon armor was developed parallel to the Scout armor in the Office of Naval Intelligence's Beta-5 Division Ordnance Testing Facility in Swanbourne, Perth, Western Australia. The armor was designed to provide the wearer with stealth capabilities and with little or no loss of endurance, specifically by reducing its infrared signature, reflective surfaces, and Cherenkov radiation emission.

Usage
SPARTAN-B312 applied to use the Recon armor in its Mark V testing phase, and was given permission to use it.

ONI operative Veronica Dare wore the S-1/ONI Recon BDU version of the helmet. Updated Recon armor was also used by Kilo-Five members Vasily Beloi and Malcolm Geffen.

Specifications
The helmets visor system was changed to a APL-72 visor system. The chest has an infrared signature modulator, and a X900-Boulder emission shroud (IMC-spec). The reactor pack has a Bravado-120-B4 fitted stabilizer for masking reactor footprint.

It offers improved movement stabilizers and adjustable shield distribution channels for versatility during deep-field reconnaissance.

The GEN2 Recon helmet also contains a highly classified Auspex battlenet uplink featuring state-of-the-art ONI counter-cyberintrusion and firewall routines. The armor itself is fitted with emissions baffling and plasma electronic support activity sensors for observation missions behind enemy lines.

The greaves are an off-market system that feature exposed shield conduits.

Development history
As a result of the UNSC Ordnance Commission in 2553, Imbrium Machine Complex took over production of the Recon variant after the Human-Covenant War, where they refined and improved the existing architecture. The GEN2 variant was tested at Anakara Resiliency Chamber with it being quickly done, as by January 2553 a copy of the armor was on board the.

Usage
Most operators indicate the armor has a notably higher resiliency and much leaner reaction-time margin.

GEN2 compatibility
In the post-war era, custom-built upgraded and up-armored RECON [GEN1] helmets remain in service with individual ONI operatives. Such helmets, equipped with cutting-edge stealth and cyberwarfare suites, were used by ONI teams responsible for information sanitation operations on Created-occupied Earth.
