The following is based on Van Buren and has not been confirmed by canon sources. Their existence is hinted at on the only accessible terminal on the same level, in an engineer's log entry noting that a suit made of 'unknown material' was found after the NCR took the dam. There are several wooden crates here, and all but the one containing the suits of armor is empty. They are located in a storage room with some radioactive barrels, in a wooden crate to the left as the player enters the room. Two suits of Chinese stealth armor can be found on the office level of Hoover Dam. However, recon armor is considered 'Medium' armor and therefore reduces walking speed and ability to sneak well, while the 'Light' Chinese armor will not. The lower durability and lower DT also makes the recon armor more appealing. This is likely because the suit has been improperly stored and its stealth capabilities have been damaged by time. Unlike the Chinese stealth armor from Fallout 3, there is no invisibility field. It is repaired with recon armor, or with other Chinese stealth armor. The Chinese stealth armor is a light armor that grants the wearer a sneak bonus of +5. 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 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 allowed China to counter American brute force with subterfuge and deception, although some units were captured and reverse engineered by the Americans. 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. 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 blue, form-fitting body suit with an opaque face plate is a suit of armor designed for one thing: Making the operator nigh-invisible. The following section is transcluded from Chinese stealth armor.
