ISIS has been known to carry out night raids with the help of AN/PVS-7 night vision googles.The United States, NATO, and their allies have already began moving on to AN/PVS-14 googles, but the 7s are still in wide use by forces around the world. The head-mountable goggles feature image intensifiers to assist vision in extremely low light situations, but the device is auto-gated to prevent damage due to intense light. The goggles are also water-proof and charged with nitrogen to prevent internal condensation.
