The C80 Combat Environment Suit is a lightweight, all-environment body armor suit, designed by CDMC, which entered use with the armed forces of the Caspian Democratic Union in 15 ABY. It was developed to meet the combined requirements of the Union Marines, the Caspian Navy, and the various Provincial Armies, to be used by light infantry units, vehicle crews and spacers. This resulted in a long development cycle, as CDMC's engineers had to accommodate a diverse (and often contradictory) set of requirements, but the ultimate product has proven to be versatile and well-liked by Caspian personnel.
