INFILTRATOR-class Mjolnir

INFILTRATOR-class Mjolnir is a variant of the MJOLNIR Powered Assault Armor (GEN2) developed by Hannibal Weapon Systems.

Overview
The helmet has a wide-range tracking feed, and a Q9L-3 Kotka comm-viel for transmission masking. The helmet is also one of the few that can fit the heavily classified ZILANT comm suite needed to access ONI's various hidden microsatellite constellations.

The suit has a ingress cloaking module to mask motion silhouettes at most spectrums. The reactor pack has a hardened uplink node for off-world communication.

Development history
INFILTRATOR-class Mjolnir, was manufactured by Hannibal Weapon Systems and was tested in the WG/Facility 93-00/Kotka. It was also tested on the orbital battleclusters above New Carthage, where Spartans were jettisoned and were forced to use re-entry packs to reach heavily protected weapon platforms, infiltrating them to accomplish specific objectives and escape without being hindered by passive inhibitors or guards.

Infiltrator-class armor was also designed to assist Spartan operatives in gaining undetected entry into heavily fortified enemy sites.

Usage
Some spartans prefer the suit for its less opaque stealth systems over other systems.
