SCOUT-class Mjolnir

The Mark VI MJOLNIR Powered Assault Armor/S variant, more commonly known as Scout Armor, or simply Scout, is a type of United Nations Space Command body armor. The armor uses advanced materials to give it stealth properties.

Development and History
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 ONI's Ordnance Testing Facility B5D at Swanbourne, Perth, in Australia.

Helmet Characteristics
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 usually worn when participating in motor sports, such as motorcross.

Shoulder Characteristics
The shoulders are angular and straight. 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
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 an H-shaped plate over the upper torso, and a pair of articulated plates attached to its bottom.

Trivia

 * In the official Halo 3 Strategy Guide, it falsely states that the shoulder pads are unlocked by gaining the We're in for Some Chop achievement.
 * The Scout chest piece had a glitch; it would sometimes re-lock itself, even if the requirements for unlocking it had been achieved. Luckily, Bungie fixed the glitch in the first Halo 3 Title Update (TU1).
 * McFarlane has produced a Spartan Soldier Scout armor with different colours and interchangeable armor pieces that can be used on other Spartan figures.
