SCOUT-class Mjolnir

The Mark VI MJOLNIR Powered Assault Armor/S variant, more commonly known as Scout Armour, is a type of United Nations Space Command body armor. It was first seen in Halo 3.

Introduction
Scout armour is a variant of the standard Mark VI MJOLNIR powered assault armor. The Armour uses advanced materials to give it stealth properties. It is an armor permutation in Halo 3 multiplayer, and like all armour permutations, it has no effect on gameplay.

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, making it much more expensive to develop this variant than the original Mark VI. It was tested in ONI's Ordnance Testing Facility B5D at Swanbourne, Perth, in Australia. The results gathered there showed that the SCOUT variant was very effective when it came down to stealth capabilities, but it never reached the phase of being mass produced for its SPARTAN-II wearers all because of all the expenses needed for it.

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 armour for sniping because its thin, slit-shaped visor keeps it less visible than other helmets. Its general shape could be compared to a dirt bike helmet.

Shoulder Characteristics
The shoulders are angular and straight. Unlike other shoulder pads, 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. Because they attach not directly to the shoulder, but slightly above the elbow, they would provide much greater ease of movement of the arms, similar to the C.Q.B. shoulders.

Chest Characteristics
Like in other MJOLNIR variants, the chest plate is simply an attachment that is placed onto the already existing Mark VI armour. The chest armour consists of an H-shaped plate over the upper torso and a pair of articulated plates attached to its bottom. It's theorized that the H-Shaped chest plate is merely a storage device to aid in weight distribution and allow for easier movement in certain missions involving stealth and reconnaissance.

Trivia

 * The official Halo 3 Strategy Guide, incorrectly 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 recently fixed the glitch in the first Halo 3 Title Update (TU1).
 * The Meta from the Red vs Blue: Reconstruction series wears a Scout chest plate.
 * McFarlane has produced a Spartan Soldier Scout armor with different colours with interchangeable armour pieces.
 * The helmet bear some resemblance to the Scarab Turret.
 * This helmet makes you harder to spot when using the Sniper Rifle.
 * F'Andre "Lemon Man" Norman Klaus in the machinima Marlin the Elite wears a Scout helmet.
 * The shoulder pads looks like the Halo 2-era Brute shoulder pads.
 * The chest will sometimes glitch out of existence for half a second while changing armor or playing online.
