"World's Best Night Vision vs World's Darkest Room"

"We visited the US Navy to test the best night vision goggles in the world."

See the You Tube video:

Night vision devices quite sophisticated indeed. Three types. 1. Infra-red using an illuminator. 2. Infra-red passive. 3. Passive night division device based on the amplification of surrounding ambient light of whatever sort. Testing NSWC done in a totally darkened light-proof room.

Regarding NSWC: Naval Surface Warfare Center Crane Division (NSWC Crane Division).

"The base is the third largest naval installation in the world by geographic area and employs approximately 3,300 people."

CRANE THE NAVAL INSTALLATION LOCATED ABOUT SEVEN-HUNDRED MILES [1100 km] FROM THE OCEAN.

"The base is the third largest naval installation in the world . . . White oak wood for reconstruction of the USS Constitution is harvested at this base from a grove of trees known as 'Constitution Grove'".
