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. A variant of the MJOLNIR Mark VI, the Scout Armor uses advanced materials to give it stealth properties, while the 'R' variant reduces the IR signature and radiation.

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 Western Australia.

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 usually worn when participating in motor sports, such as motocross.

Shoulder Characteristics
Unlock: Unlock the Mongoose Mowdown Achievement.

The shoulders 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.

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 colors and interchangeable armor pieces that can be used on other Spartan figures.
 * In the Halo Encyclopedia, on the page which discusses the different Spartan armor permutations, the Scout helmet is mistakenly taken as the Rogue helmet, but is also shown when discussing the Scout permutation.
 * Jun-A266 wears a MJOLNIR Mark V (B) helmet with characteristics of the scout helmet.
