SCOUT-class Mjolnir

The MJOLNIR Powered Assault Armor/S variant, more commonly known as the Scout armor, is a variant of the MJOLNIR Powered Assault Armor that was developed by the Office of Naval Intelligence. The Scout armor uses advanced materials to provide stealth properties, while the 'R' variant reduces infrared signature and radiation emissions. In the case of the Mk. V version, the helmet's visor also includes an enhanced optics system.

The Scout variant was developed for use with the MJOLNIR Mark V Powered Assault Armor and was later upgraded to function with the MJOLNIR Mark VI. The variant was carried over to the GEN2 System.

GEN1
The Scout and Recon projects were run as parallel projects intended to develop a single variant of the MJOLNIR Powered Assault Armor with stealth capabilities and no impact on endurance; however, the Scout variant relies heavily on highly advanced materials. It was tested in the Office of Naval Intelligence's Beta-5 Division Ordnance Testing Facility at Swanbourne, Perth, in Western Australia.

GEN2
The GEN2 variant was mostly unchanged from the Mark VI design. It was favored by Class-8 FDO (Forward Deployed Operators) as it contained the most capable covert anti-tracking system and shroud-induction packages available for use. Commander Palmer, leader of the 's SPARTAN-IV contingent, wore a GEN2 Scout suit.

In Halo: Reach, the Scout helmet features drastically different aesthetics than the Mark VI Scout helmet seen in Halo 3. It resembles the MJOLNIR Recon variant in terms of basic design, with the visor being a wide slit. The player must achieve the rank of Captain to unlock this helmet.

Two upgrades are available for the helmet, the first adds a Hardened Uplink/Remote Sensor Package (HU/RS), and the second adds a Chemical, Biological, Radiological, and Nuclear Module with a Command Network Module-Improved on the right side (incorrectly called CNM) (CBRN/CNM, should be CBRN/CNM-I). The HU/RS attachment in this form is unique to the Scout helmet, in all other appearances it looks more like a helmet mounted flashlight.

Spartan-III commando Jun-A266 wears this Scout helmet.

Helmet characteristics
Unlock: Unlock the Used Car Salesman Achievement.

It features a cap-like protrusion, along its rim and a beak-like protrusion under the chin. It is usually best to use this armor for sniping because its thin, slit-shaped visor keeps it less visible than other helmets. Its general shape could be compared to a full face helmet or the helmet worn by UNSC marines.

Shoulder pauldron characteristics
Unlock: Unlock the Mongoose Mowdown Achievement.

The shoulder pauldrons are straight and angular. Unlike other shoulder pieces, the Scout shoulders are attached slightly above the elbow, instead of on the shoulder. They are remarkably similar to the original Marine armor from Halo: Combat Evolved, and the shoulder plates of the Brutes in Halo 2.

Chest characteristics
Unlock: Unlock the Too Close to the Sun Achievement.

Like the other MJOLNIR variants, the chest plate is simply an attachment that is placed onto the already existing Mark VI armor. The chest armor consists of a H-shaped plate over the upper torso, and a pair of articulated plates attached to its bottom.

GEN2
The Scout variant is available as a customization option for the MJOLNIR (GEN2) armor system. It is relatively unchanged from its previous incarnation.

Trivia

 * The official Halo 3 Strategy Guide mistakenly states that the shoulder pads are unlocked by gaining the We're in for Some Chop achievement.
 * In the first months of Halo 3 multiplayer, the Scout chest piece had a glitch; it would sometimes re-lock itself, even if the requirements for unlocking it had been achieved. Bungie fixed the glitch in the first Halo 3 Title Update.
 * The Halo Encyclopedia mistakenly displays the Scout helmet in place of the Rogue helmet, but also shows the Scout helmet when discussing the Scout permutation.
 * The Scout helmet closely resembles the helmets used by Veritech and Destroid pilots from the anime RoboTech.
