- “The Mk. IV [G] variant is an up-armored prototype based on the basic Mk. IV helmet.”— Description of the Grenadier helmet.
The Mjolnir Powered Assault Armor/Grenadier is a variant of the Mark IV Mjolnir Powered Assault Armor. It served as the basis for all subsequent armor variant development programs, and is also compatible with later models such as the Mark V. Additionally, the variant served as the test bed for incorporating energy shielding technology with the Mjolnir.
The Grenadier variant is known to include at least a helmet, chestplate, a shoulder piece, and knee guards.
The helmet is available at Warrant Officer rank for 25,000 credits, the UA (Up-Armored) attachment is available for 5,000 credits and the UA/FC attachment for 2,000 credits. The Grenadier UA chestpiece, the one Jorge wears, is available at captain for 4000 cR
