Sight

In the Battlefield series, optics can either refer to a gun's optic sight/scope or a vehicle's aiming/imaging system.

Weapons
In every Battlefield game, the player can unlock and equipt gun sights in place of the default weapon iron sights. These optical sights range from red dot sights to magnified rifle scopes and serve to give the shooter a better view while in ADS and aid in target acquisition. Additionally, some sights, such as high zoom rifle scopes, can only be attached to certain weapons.

Vehicles
In most Battlefield games, vehicles have access to unlockable imaging/target acquisition systems. Commonly, these vehicle specializations include some sort of thermal imaging upgrade or enhanced zoom upgrade to the vehicle's main sights. In games where the player can choose their vehicle loadouts, optical upgrades are often avaliable to many different vehicle types (in some cases however, the same upgrade can have slightly different effects depending on the vehicle it is equipted to).
