Chinese stealth armor was used during the Chinese invasion of Alaska and was the Chinese solution to invasion by U.S. forces in power armor. It was available to elite Chinese Crimson Dragoon troops as well as the Black Ghost counter-insurgency/terror units before and during the Great War.
Earlier Hei Gui models were also used during raids against the Hoover Dam secret laboratory and Limit-115 laboratory.
The armor is a form-fitting armored jumpsuit, with stealth camouflage system embedded. It generates a modulating field that transmits the reflected light from one side of an object to the other, making a person much harder to notice (but not completely invisible). The technology was the basis for the unstable "Stealth Boy" wrist units developed in the U.S.
pcps3xbox360 If the armor breaks while the player has the stealth field activated, there is a possibility that the stealth field will stay active even after changing to a different piece of clothing or exiting sneak mode. This can be fixed by repairing the armor and toggling sneak mode while wearing it, or loading an earlier save. [verified]
pcps3xbox360 With the stealth suit on you can equip as many pieces of headgear that you want and raise many stats substantially. If you do this, and then equip another suit of armor (ex. power armor) you will still be wearing all the headgear. See Operation: Anchorage bugs for more details. [verified]
pcps3xbox360 When a companion has the armor equipped and is crouching (activating the stealth field) you can trade items with him/her and swap the armor with another clothing article and when you exit dialogue the stealth field will remain whenever the companion is crouched. This is useful if you want to sneak through areas with a high concentration of enemies, (such as Evergreen Mills) without the possibility of the death of the companion. [verified]

ps3xbox360 Sometimes when equipping enclosed headgear like a power helmet, switching to the stealth armor, and removing the headgear will cause the player's head to seem gone.
