This is an older armor concept from my WIP world, "We are the Forgotten."

HMCP - High Mobility Combat Armor.

The purpose here was to design a suit of ballistic armor that could resist higher calibers, as the setting takes place in a fiction world in the year 2087: certainly technology has advanced to allow for thin polymers to remain intact with high impact.
The system utilizes thin plates of hexapolycarbon cells, which are designed to equally distribute the force of impact through out the unit. The abdomen portion of the armor is made up of overlapping cell sheets, crafted to slide over each other with minimum noise and to allow for free movement. Because of this, general sizes were developed for the body type of the wearer to improve upon this aspect. Heavy versions of the armor used more of this technique throughout, including behind the legs, over the tail, on the elbows, knees and neck. This design was never generally issued, and individuals who bought them were mainly designated as support gunners.
The plates are fitted with attachment points for load bearing equipment and various electronics that might be fitted.
Underneath the plates a Kevlar-like material know as Kypr-Seritum is used to make the dense, yet flexible cushion to resist shock. Initially, these pads were fitted onto the plate carriers and plate harnesses, however, this proved to become too bulky, and increased armor production times. Later in development, these pads were sewed on to the standard ACU underneath.
