SCOUT-class Mjolnir

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

Introduction
Scout armour is a variant of the standard Mark VI MJOLNIR powered assault armour. 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. 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 dirt bike helmet.

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 armour 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, 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 armour with different colours with interchangeable armour pieces.
 * The shoulder pads looks like the Halo 2-era Brute shoulder armor.
 * There have been cases that the katana would disappear in gameplay if the scout armor was equipped with it.
 * The visor is the smallest out of all the other helmet visors.
 * Since it's called Scout some players have worn it and called themselves scout troopers from Star Wars.
