— Battlelog description
IRNV Optics are a type of vehicle optics in Battlefield 4.
The IRNV Optics appear as an "Optics" specialization for the main battle tank, mobile anti-air, attack boat, infantry fighting vehicle and the attack helicopter. IRNV Optics function similarly to the IRNV Scope that is available on weapons.
The IRNV Optics can be used in conjunction with the standard daytime optics. The optics assist in target acquisition at close to medium ranges, but fail to perform effectively at long range.
The IRNV Optics are unlocked at 4,500 score for the Mobile AA, 11,000 score for the infantry fighting vehicle, 13,000 score for the attack boat, 14,000 score for the attack helicopter and 21,000 score for the main battle tank.
