Night Vision Goggles
A night vision device (NVD) is an optical instrument that allows images to be produced in levels of light approaching total darkness. The term usually refers to a complete unit, including an image intensifier tube, a protective and generally water-resistant housing, and some type of mounting system. Many NVDs also include sacrificial lenses, IR illuminators, and telescopic lenses.
Night vision goggles enhance any ambient light and allow the wearer to ignore Dim or Dark conditions entirely and treat Pitch Darkness as normal Darkness. It has no effect if absolutely no light is available at all (such as the total darkness found in caves). Also, when wearing a monocular device, the user suffers –1 to Notice rolls due to his reduced peripheral vision. Night vision goggles require a small battery that provides about four hours of use. A bright light shined in the goggles forces the wearer to make a Vigor roll or be Shaken.
The AN/PVS-14 Monocular Night Vision Device (MNVD) is in widespread use by the United States Armed Forces as well as NATO allies around the world. It uses a third generation image intensifier tube, and is manufactured by Litton Industries (Now L-3 Warrior Systems) as well as the ITT Corporation (Now ITT Exelis). It is often used ‘hands free’ using a head harness or attached to a combat helmet. It can also be used as a weapons night sight.
The AN/PVS-15 is based on the DoD nomenclature for the M953. It is a purpose-built ground operations binocular night vision device and is currently issued to members of USSOCOM.
