UA attachments

UA, short for up-armored, is a series of supplemental armor attachments and accessories compatible with the MJOLNIR Powered Assault Armor and battle dress uniforms worn by UNSC infantry.

Specifications
The UA category encompasses various attachments that are compatible with the helmet, shoulders, chest, wrist and thigh components of the MJOLNIR Mark V and MJOLNIR [GEN3] armors. The UA series are typically armor reinforcements with different purposes depending on the modules. They can either come as a singular module or as a kit.

Usage
Many of the UA pieces are not exclusive to the MJOLNIR system, but are in use by regular UNSC Army or Marine troops as well. Some UA attachments are designed for specialized personnel, like Spartans tasked with breaching or members of Spartan containment teams.
