The Sniper Rifle System 99C-S2 Anti-Material (abbreviated SRS99C-S2 AM), otherwise known as the  Sniper Rifle is a United Nations Space Command firearm.

Background

The SRS99C is the primary Sniper Rifle used by UNSC. It is, alongside its Covenant counterpart the Particle Beam Rifle, the most accurate and arguably the most powerful small-arms weapon in both arsenals. It is modular, with the scope, stock, barrel and firing mechanism capable of being swapped to match a mission profile. This rifle is closely modeled on the NTW-20 present day Sniper Rifle.

The SRS99C-S2 AM is designed to be used at medium to long ranges and is equipped with an electronic scope for precisely this purpose. It is tremendously useful in its designated role, considering its extraordinary range, surpassing any other weapon of comparable size, and its incredible stopping power even against body armor and Covenant shields (i.e., those of an Elite.) By far, its most useful application in Campaign mode is taking out the higher-ranking enemies in a group to destabilize their squad's discipline and morale (which makes combat much easier). A headshot against any Covenant infantry except a Zealot and Hunters,results in an instant kill; Hunters fall from one shot to their unarmored torso or neck and many Brutes require only two rounds to the head (one to get past the protective helmets they often wear). When playing in the highest difficulty, Legendary, the Major Domo Elites will take two shots to the head and the Zealots will take three. Also when the night vision function is turned on, by turning the flashlight on while scoped. One can see an invisible (cloaked) Elite very easily if he is moving fast enough. When playing online, some players use the Sniper Rifle to great effect when camping. For example, skilled users may crouch inside a confined hallway and fire without the use of the scope from close range, resulting in many instant kills. In competitive games between two organized teams, both will always have a sniper. Despite it's obvious role, the Sniper Rifle is can be highly effective at close range in the hands of a skilled operator, as the highly damaging round is just as powerful close-in; a single round followed by a melee strike will kill a hostile almost instantly. This does not account for Flood, however, due to the body organization. See Disadvantages. Bottom line: If you don't kill them with the first shot, then they'll bite the dust on the next one. As an added bonus, the Sniper Rifle has a fast melee speed. One can even take out an Elite in close quarters with the Sniper melee. The Sniper Rifle is also capable of multiple rapid follow-on shots, unlike the Beam Rifle, which requires a reduction in maximum firing rate lest the weapon overheat.
