Needing something to cover every race the same and offer protections even when not wearing standard uniforms, the UAS was created. A standard solid black suit that is made of a stretchy material which fits to any size and shape, offering comfort and protections while also staying within empire guidelines.

The UAS Mk 1 was the standard for a long time as technology slowly improved the suits themselves. Made by infusing bio-electrostatic gel into the fabrics woven into the under armor, this gel has certain temperature regulation and impact resistance properties. The gel helps to distribute the force across the suit reducing shock wave effects and improving blast range survivability.

The UAS Mk 2 was a breath of fresh air due to its increased breathability and cooling as well as its absorption of the body's electromagnetism. This improved the functions of the UAS greatly.​

The WUA-01 is a variant of the UAS MK 2. It is much thicker being close to the thickness of the uniform itself as it offers the highest levels of protections and is powered by a small micro cell. Being charged by an energy dock or by magic, the suit enters into combat mode and activates the micro cell battery to super charge the suit. Although the battery only lasted 15 minutes, it was a god sent against power mech units and other super heavily armored enemy soldiers in the field.

The MUA-01 was developed to allow users to use their magics more freely. With many magic casters using some form of catalyst to cast their magic, more and more users are able to freely shoot off spells so long as they have the power to do so. As the empire began to train the mages to use the magic around them as well as in themselves, they made a suit which wouldn't block the natural magic around them. Ultimately this was a resounding failure across the board. The only good thing which came from the extensive battle tested armor was the ability to enhance it with magic.

The MUA-02 was rapidly developed to allow users to use their magic. With the failure of the Mk 1, the newer armor suits didn't fail as horribly. With better Magical and energy absorption systems in place, a battery which stored energy for the suits usage was naturally charged by the users Magical powers. Unfortunately the enhancement abilities of the suits were lost due to rapid iteration and development.​

The MUA-03 was developed with all the goals in mind of the first 2 suits before it. It allowed for extensive spells to be fired off rapidly while being enhanced through tubes with runic scripts inscribed down the armor's trim lines. Offering great protection and magical absorption, the only main issue was the amount of magic absorbed from the environment or user. The percentage was too low as it was losing too much magic in the exchange. Trying to keep up the magical capabilities that are needed by various combat magic styles, the suits needed to be further.

The WUA-02 is an upgraded version of the WUA-01 and offers a huge improvement to the battery life with rapid regeneration using all sources from energy to magic around the user to keep it charged. This new iteration features all the same protections and allows for the battery to be charged even while it is taking damage. Being charged by an energy dock, magic, the environment, or even radiation allows the suit battery to last an average of 60 minutes for each fully charged battery. Additional battery modules can be inserted and installed in the suit allowing for even more extended use.

The MUA-04 was finally developed as a magical under armor suit for use within the empire. It allowed for extensive spells to be fired off rapidly while being enhanced through tubes with runic scripts inscribed down the armor's trim lines as well as offering magical points on the tops or bottoms of the hands to act as a catalyst. Offering even greater protections with enhanced magical absorption, the amount of magic absorbed from the environment or user was increased to a minimum of 80% and an absolute maximum to 98%. The fall off percentage was within range and not much magic was lost in the exchange.
