GRENADIER-class Mjolnir

The MJOLNIR Powered Assault Armor/G, also known as Grenadier, is a variant of the MJOLNIR Mark IV Powered Assault Armor.

Specifications
This variant was a test bed for incorporating energy shielding technology with the MJOLNIR program. The helmet features an up-armored configuration with heads-up software that adjusts to combat situations that improves the user's performance and suitability. The shoulder pauldrons for this armor set are categorized as "blast-guard pauldrons".

Development history
It was introduced in around 2535, ten years after the first version of MJOLNIR entered service. It was based on a design that originated from the first prototypes of the Mark IV helmet, one that was upgraded to withstand violent concussive force. The [G] variant served as the basis for all subsequent supplemental armor development programs and is compatible with later models such as the Mark V. The [G] variant served as a test bed for incorporating energy shielding technology with the MJOLNIR program, though these tests were not successful; energy shielding had previously been tested by SPARTAN-II Red Team in 2531.

After the first wave of GEN2 systems, based on requests of veteran Spartan-II and Spartan-III operatives, the UNSC Ordnance Commission considered reassessing a refined and upgraded version of the Grenadier suit. This led to the creation of the INDOMITABLE-class Mjolnir.

Usage
This variant saw limited use as other variants filled the same role instead. Jorge-052 wore a variant of the Grenadier helmet with the UA (Up-Armored) attachment, as well as the knee guards, left shoulder, and UA chest piece.

Halo: Reach
"The Mk. IV [G] variant is an up-armored prototype based on the basic Mk. IV helmet."

All Grenadier armor types in the Armory are unlockable in the game's purchase system via the use of cR. In Halo: The Master Chief Collection, the Grenadier set is attainable in the Season 1: Noble progression system. Due to its adoption from the customized armor of Jorge-052, the Grenadier [UA] chest plate has his Spartan tag "052" written on the collar.

Production notes
The Grenadier helmet bears a striking resemblance to an early design of the MJOLNIR Powered Assault Armor/Mark IV that was removed from Halo Wars. It also resembles the Mark IV armor worn by Gray Team as seen on the cover of Halo: The Cole Protocol.
