The Sniper Rifle Series 10x sniper scope.

The BR55HB SR 2x Scope.

The telescopic sight, commonly called a scope, is a device attached to a weapon used to give additional accuracy using a point of aim for weapons such as firearms, airguns and crossbows. Other sighting systems are iron sights and red dot sights.

Function

The UNSC uses a scope on a wide variety of its weapons, ranging from its sniper rifle variants, to its battle rifles, and even its handguns, though the handguns employ a "smart-linked" camera. All of these scopes and cameras can transmit their feeds to UNSC soldiers' heads-up displays via smart-linking. The Covenant also use scopes (e.g.; the Covenant Carbine and Beam Rifle), though the mechanics of their equipment are unknown.

There are a wide variety of scopes, each differing in type, function, and purpose. For example; the standard scope of an S2 AM Sniper Rifle is capable of 5x/10x, 2x/8x or 2x/10x magnification for long range combat, and are electronically operated. The S2 AM Scope also includes a night vision function in some models for night combat. The scopes on the BR55 and BR55HB SR, however, are only capable of 2x magnification, intended only for short to medium-range accuracy, using focusing lenses for magnification. The M41 Rocket Launcher and the fuel rod gun both have 2x scopes, as well, to better pinpoint targets and to extend their effective range.
