Chinese Stealth Armor

Hei Gui stealth armor was one of China's greatest military assets during the Sino-American wars. When equipped, it afforded the soldier a decent amount of protection (but not as much as America's combat armor), while also coating the user in an active camouflage system. America tried to copy this technology in the unstable stealth boy units.

America's counterpart to the stealth armor was power armor.

Hoover Sabotage armor
During the Hoover Sabotage, Americans caught their first glimpses of China's elite soldiers wearing the stealth armor. Because Sub-Level 1C was sealed, several of the Chinese soldiers' bodies remained in the compound.

There are two Chinese stealth armors located at Hoover Dam by 2281, presumably left there on the corpses of two Chinese agents after the Hoover Dam sabotage incident before the Great War. NCR forces found and later misplaced the suits in a storeroom with radioactive waste. These two suits differ from the Anchorage version in that they do not create a stealth field around the wearer when sneaking and have a lower sneaking bonus.

Anchorage campaign armor
The Chinese spent some time redesigning the stealth armor before issuing it to their soldiers on the Anchorage Front Line. A single copy was captured by the US and sent to several companies for study and reverse-engineering. You will find it in the armory which is unlocked after you finish the anchorage add on.
