GRENADIER-class Mjolnir

Were you looking for the Mark V GUNGNIR variant? "The Mk. IV [G] variant is an up-armored prototype based on the basic Mk. IV helmet."

- Halo: Reach armory description

The MJOLNIR Powered Assault Armor/Grenadier is a variant of the MJOLNIR Mark IV Powered Assault Armor. It was introduced in 2535, ten years after the first version of MJOLNIR entered service.

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 test were not successful; energy shielding had previously been tested by SPARTAN-II Red Team in 2531. 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.

The Grenadier variant is known to include at least a helmet, shoulder pieces, and knee guards.

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.
