HUNTER (GEN2)
ARMOR: Sophisticated and lethal, HUNTER-class armor incorporates Watershed Division’s latest warfighting technology. Synergistic with other Mjolnir-compatible tactical systems.
HELMET: Though still considered a prototype implementation, the HUNTER’s sensor suite enhances situational and threat awareness. Designed to impress even jaded ONI bureaucrats.
MANUFACTURER: The Watershed Division
SPARTAN VALE
COPPERHEAD (GEN2)
ARMOR: A multipurpose armor system built from the ground-up for covert “special activities,” COPPERHEAD armor is rarely seen since it is jealously guarded by ONI’s direct action teams. Requires Eyes Only Top Secret clearance to review maintenance logs.
HELMET: Packed with systems to exploit the complex “terrain” of human and alien society. The origin of COPPERHEAD’s “militarized anthropology” decision support system can be traced to innovative tools crafted for use by Colonial Administration Authority field teams working during the darkest days of the Insurrection.
MANUFACTURER: The Watershed Division
SPARTAN TANAKA
TECHNICIAN (GEN2)
ARMOR: Variant used by Spartan combat engineers and field techs. The TECHNICIAN Mjolnir system features a battlenet node and custom machine interlink that can process and curate vast amounts of data.
HELMET: Effectively a cutting-edge techscanner array packed into a wearable helmet, the aptly-named TECHNICIAN helmet allows the wearer to function as a mobile diagnostic center. In a pinch, the helmet sensors can also scan living creatures.
MANUFACTURER: Beweglichkeitsrüstungsysteme
SPARTAN BUCK
HELLJUMPER (GEN2)
ARMOR: Pet project of Cascade’s CEO, a former ODST. A small number of HELLJUMPER prototypes have entered Spartan service under a research partnership between the UNSC and Cascade Stronghold Technology.
HELMET: Though development delays kept it from consideration by the UNSC Marine Corps, only minor modifications were needed to make the HELLJUMPER helmet fully compatible with GEN2 Mjolnir.
MANUFACTURER: Cascade Stronghold Technology
