America's Army/Night Vision Goggles

In maps that have relative dark places, each United State Personnel (none for IF, sorry) are issued with a pair of NVGs, which provide vision in the dark by amplifying ambient light sources. However, while it lits up the places, use of NVG reduces FOV; Flashbang effects are worsened and light sources causes extreme glare. Also, in places that have very dense fog, the NVG reduce long range visibility (though do help on closer range)

Luckily, there are currently (2.6) no delay when switching from NVG mode to normal mode; as such, a tip for target aquisition is to toggle between nvg and regular vision.
