PATHFINDER-class Mjolnir

PATHFINDER-class Mjolnir is a variant of the MJOLNIR Powered Assault Armor (GEN2).

Design details
The helmet's visor has self-actuated, independent intel assessing systems. It also has heavy-gauge atmosphere filtration vents. The IMBR-119 close-fitting pauldron units allow smooth mobility in dense foliage. The chest has a extended canopy mount.

The armor contains anterior torque couplings, a Bravado-120 fitted stabilizer unit, and alternating heat-tempered balance drives.

Dedicated expert systems or dedicated AIs can be housed in the PATHFINDER helmet for on-site analysis of signals intelligence. These are run in a separate virtual machine from the rest of the suit's systems for security reasons.

Development history
The Pathfinder variant was manufactured by Imbrium Machine Complex It was tested at Ankara, Mare Imbrium on Luna in the brutal outland conditions of Bosque de Negro, where IMC determined the overall viability of the armor. It is intended primarily for use in operations that take place deep in unknown territory.

Usage
During testing IMC deployed a number of Pathfinder-equipped Spartans into Bosque de Negro. These Spartans survived and thrived on the forest's deadly terrain and wildlife.

Pathfinder has broken several challenge-duration records during its brutal stints in Bosque de Negro.

The PATHFINDER armor is already popular with Spartan force reconnaissance, and is now seeing extensive use with tactical signals intelligence elements.
