Working off of a failed prototype of the Raiden, research and development of the Kage began in March of 3051 with the first prototypes unveiled in May 3052, however it soon became apparent there was a problem in the design.
Indeed the Kage was meant to provide an alternative to the much-respected DEST Infiltration Suit for missions in which DEST teams could expect heavy opposition, and since production started in 3056 the battle armor has virtually replaced the older Sneak Suit. Built for reconnaissance and battlefield infiltration, development of the Kage was a joint operation between Internal Security Force scientists and Draconis Elite Strike Team advisers. The Kage (Japanese: 'shadow') light battle armor was one of the first battle armor designs produced by the Draconis Combine after the Truce of Tukayyid.
