Night vision goggles that help troops own the night.

"The soldier will be able to ... change darkness into day with one flick of a wrist on the infrared dial and switch."

Night vision was developed in the 1940s, but was not fielded in goggle form until 1977.

Night optical/observation devices, or NODs as soldiers call them, are standard issue for most troops in the field these days. However, even Rigg couldn't predict the rise of even better gear, such as thermal devices that can pick up on the human body's heat signature.
