The date which is most notable of use is by the 301st engineering crew as they used a modified KIS unit in combat as they were under attack while doing maintenance within the newly taken territory. Seeing the ability to lift super heavy weapons like tank turrets and tank machine gun emplacements, the higher ups were impressed by how these suits offered great mobility and power. Changing the base level armor came in a few years time as more and more people slipped out of the harness of the KIS which led to more injuries and wounds in combat.

​The SA-01 was the solution to all of the problems. Using a super heated pipe piece, they dug a groove down the main spine of the armors back so the harness unit would slide and lock in place. This fused the armor piece to the KIS when worn for long times or exposed to heat. A new solution was needed to not lose armor suits or a KIS in the process.

The SA-02 or SAL-01 was a harness built around the armor piece and then a person slipped into the bars to use the SA with the KIS attached. This method was widely adopted for goblins and other smaller races who could easily fit into the small holes. A short production cycle made for the armor to be pushed off of standard ships and onto the smaller races.

The SA-03 or SAH-01 Was a heavier armored variant of the SA-01 while being developed along the same time. Although additional armor pieces could be welded to it for more armor at the closet of speed and power, it wasn't used often as it became harder to use for the average person.

The SA-04 or SAH-02 was an even heavier but sturdier variant of the SA-03 or SAH-01 allowing for a huge range of protections and thicker armor plates. These soldiers were inside their armor and were treated more like knights and champions instead of random crew coming and going armor to armor.

The SAL-03 is the final variant of the newly upgraded SA-02 or SAL-01. A second variant was created that didn’t improve any details so its entire production line was stopped and only a few were ever created as mock prototypes. Development continues as the SAL-03 was created. It is larger and not fused together, instead being designed and made to attach to a KIS. This armor offers the highest levels of protection and unique modular capabilities for other armors to encase the SA. The standard normal armored SA unit within the empire. At the same time they took the SAL-03 and gave it heavier armor plates and reinforced materials allowing for stronger yet bulkier combat power. Although it was considered top of the line, new technologies came later on which revolutionized the armor creation aspects allowing for the same levels of strength in a lighter fashion. This changed the SAL-03 into a better version but didn’t warrant a new model like the Heavier Variant.

The SAH-05 is the final variant of the newly upgraded SA-04. This armor is top of the line in all stats and comes in various sizes for many of the races to use. Some specialized combat roles use this armor instead of the other specialized armor due to the integrated systems and lack of need of heavier armors. As this armor is a standard issue, it has become one of the most widely used across the black empire due to its ease of production. As it is the standard heavily armored SA unit within the empire and is generally considered an all rounder purposeful unit, it falls behind the heavier or more specialized units.
