Chinese stealth armor, also known as Hēi Guǐ (黑鬼) stealth armor (lit. Black Ghost stealth armor), was one of China's greatest military assets deployed during the Sino-American War.


This dark blue, form-fitting body suit with an opaque face plate is a suit of armor designed for one thing: Making the operator nigh-invisible. 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. The end result is near-perfect active camouflage. The body suit 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.[1][2] Deployed under the designation Hei Gui, the suit allowed China to counter American brute force with subterfuge and deception, although some units were captured and reverse engineered by the Americans.[3]

The suit was just barely out of prototype stage around the time of the Sino-American War and, as such, the refinement of the technology varied. 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.[4]

The underlying principle of bending light was reverse engineered by the United States from captured Chinese suits in two ways. Robert Mayflower reverse-engineered captured Chinese stealth armor to create the portable, but unstable Stealth Boy 3001 units.[5] Big MT researchers focused more on the suit itself and its stealth-enhancing properties, taking the Chinese suits apart and then designing a new stealth suit from scratch. This resulted in the creation of two prototypes before the war: the assassin suit and the stealth suit mk II, which surpassed the original in nearly every aspect.[6]


Anchorage campaign armor

Gameplay article:

The pinnacle of Chinese development before the war, issued to elite Crimson Dragoons on the Anchorage Front Line. Several suits of this type were captured and formed the basis of the aforementioned research efforts.

A single suit is found in the Virtual Strategic Simulations bunker after the completion of the Operation: Anchorage add-on.

Hoover Sabotage armor

Gameplay articles:

During the Hoover Sabotage, Americans caught their first glimpses of China's elite soldiers wearing the early model stealth armor. Two Chinese stealth armors remain at Hoover Dam by 2281. They were erroneously placed in a radioactive waste storeroom during NCR cleanup operations. These two suits are out of juice and do not create a stealth field around the wearer. However, they still have the same high quality construction, making sneaking easier.

Behind the scenes

  • In Chinese, Hēi guǐ (黑鬼) literally translates to "black ghost".

    "{5401}{}{A RobCo Stealth Boy 3001 personal stealth device. Generates a modulating field that transmits the reflected light from one side of an object to the other.}"
    Note: This is a reverse-engineered Chinese technology and provides information on the underlying mechanics.
  2. Museum of Technology placard: "This is the RobCo "Stealth Boy" Model 3001 Personal Stealth Device. Developed by Robert Mayflower, the Stealth Boy generates a modulating field that transmits the reflected light from one side of an object to the other making the bearer almost invisible to the untrained eye."

    "Could you repeat for the general what you just told me?"
    > Posit. Chinese stealth technology far outstrips our own capabilities. Posit. The Chinese intelligence apparatus is sufficient to conceal large scale research operations from American operatives. Conclusion. The Chinese have a 91% chance of having conducted large scale experimentation with Stealth Tech.
    "Large scale? What do you mean? What are their capabilities?"
    > American projects involving this technology (refer to "Stealth Boy") have merely reverse engineered captured Hei Gui suits. The underlying science of this technology is unknown. So the theoretical limits are also unknown. However the so-called "Ghost Fleet" that station A-31 and B-19 reported in November may indicate that testing has already commenced with submersible vessels.
    "Dear God. You think they have stealth subs?"
    > A second order approximation is inconclusive. Explanation. The logic chain of these assumptions have too much variability. Further data is required.
    "So you can't even give me a guess?"
    > Machine/human interface aborted.
    "Sorry, sir. We're working on some of her glitches. P.A.M... well, she gets real stubborn when she's doing too much guesswork."
    "Stubborn? She's a machine."
    "Sir. With each new version, well, she's getting quirky."
    "There's no way I'm taking this stealth sub nonsense to the Joint Chiefs unless I have proof. It's goddamned ludicrous to think the Chinese have been working on something this big and we've heard nothing."
    > Virtually no actionable intelligence has come out of the Shaanxi Province for 3.1 years. However, the province reports a spike in the imports of complex polymers and other key synthetic compounds. The quantity in question is consistent with stealth technology research on the macro scale.
    "Until you can give me something concrete, I don't want to hear another goddamned word about this."

This armor appears to be a more recent prototype of the same HG stealth armor captured from enemy infiltrators at the Hoover Sabotage. Presence of Dragoon units suggest that General Jingwei may already have relocated to Anchorage. Stand by for confirmation of report." Cut contentIcon cut.png
