SCOUT-class Mjolnir

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

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

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 advanced materials. It was tested at ONI's Ordnance Testing Facility B5D at Swanbourne, Perth, 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 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.

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

Trivia

 * The official Halo 3 Strategy Guide incorrectly states that the shoulder pads are unlocked by gaining the Used Car Salesman achievement.
 * The Scout chest piece had a glitch, it would sometimes relock itself, even if the requirements for unlocking it had been achieved. Luckily, Bungie recently fixed the glitch in the first Halo 3 Auto Update (AU1).
 * The Meta from the Red vs Blue: Reconstruction trailer wears a Scout chest plate.
 * This is by many fans to be considered the ugliest armor in Halo 3, and on the short Machinima EVA Sucks, the helmet is said to "look like a duck".
 * The shoulders resembles the Halo 2 standard brute shoulder.
