While the first unit was merely a standard suit of armor, built to test the validity of the pattern, the Mark II became a unique, computerized platform, combining the best technologies available to Big Mountain.

After the proof-of-concept suit was completed, work began in earnest on an actual prototype.

Created by Big MT researchers in the X-13 research facility using captured Chinese stealth armor technology as a basis, the aural stealth suit was supposed to be a next generation, cutting edge infiltration suit, to be used in the war effort.
