The underlying principle of bending light was reverse-engineered by the United States from captured Chinese suits in two ways. Some Chinese infiltrators on American soil, such as those captured during the Hoover Sabotage, used early generation suits, while the Crimson Dragoon troopers deployed in Alaska used cutting edge iterations granting long-lasting invisibility. The suit was just barely out of the prototype stage around the time of the Sino-American War and, as such, the refinement of the technology varied. Deployed under the designation Hei Gui, the suit was worn by the elite 'Black Ghost' counterinsurgency and terror units, it allowed China to counter American brute force with subterfuge and deception, although some units were captured and reverse engineered by the Americans. The bodysuit is designed to maximize the effect by simplifying the wearer's silhouette and creating flat surfaces where possible to reduce the complexity of the area being camouflaged. The end result is near-perfect active camouflage. Harnessing Chinese expertise in stealth technology, the suit contains a man-portable device that generates a modulating field that transmits the reflected light from one side of an object to another. This dark black, form-fitting bodysuit with an opaque faceplate is a suit of armor designed for one thing: Making the operator nigh-invisible.
