The "Prototype Voron-Certified Combat Exoskeleton" or "M1887" is a prototype of the future standard issue powered exoskeleton for VORON forces, designed with the user in mind - the armor was originally meant to change roles with a touch of a button. Later on, the development team for the M1887 realized that their vision had "too many moving parts" to work properly in combat, and the system was replaced by the older, more effective AEM's (Armor Enhancement Modules) and an FMK kit (Field Modification Kit), where the user could swap exoskeleton attachments and supplemental armor padding on the fly.
