SRS99D-S2 AM sniper rifle
The Sniper Rifle System 99D-S2 Anti-Matériel, abbreviated SRS99D-S2 AM, is an anti-personnel weapon system used by the United Nations Space Command. It is produced by Misriah Armory as part of its SRS99 Series.
The SRS99D-S2 AM is a semi-automatic, gas-operated sniper rifle that fires 14.5×114mm APFSDS rounds from a 4-round magazine. It is, alongside its primary Covenant counterpart, the Type-50 particle beam rifle, the most accurate and arguably the most powerful small-arms weapon in either arsenal. The SRS99D is about 187.5 cm long and is completely modular.
The SRS99D has some notable changes from the SRS99C models. First off, it is fitted with a 5× and 10× optic that shows realtime images in infrared vision when not looking through it. When looking through it, the scope shows a target's distance and elevation. The SRS99D also has an altered foregrip and stock as well as an altered body and sports a trigger guard. The barrel also now has an iron sight. This weapon does not possess a safety and has a frame that serves as a carrying handle as well as a scope protector and a folding bipod located in front of the magazine on the underside of the rifle.
The SRS99 series 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, which surpasses any other weapon of comparable size, and its incredible stopping power even against body armor and Covenant shielding system.
By far, one of its most useful applications is taking out higher-ranking targets from long range to destabilize their squad's discipline and morale. A headshot will kill any Covenant infantry except a high-ranking Elite or Brute. Hunters fall from two shots to their unarmored torso or neck. This does not account for The Flood, however, due to their morphology. The Flood can, however, be rendered harmless by removing their limbs or by placing a round into the embedded infection form. In multiplayer, the SRS99 series can be highly effective at close range in the hands of a skilled operator, as the highly damaging round is just as powerful at close range; a single round followed by a melee strike will kill a hostile almost instantly.
The rifle's projectile has a slight travel time at great distances, and requires practice to use effectively at range. When used in close quarters, its precision nature, slow reload time, small magazine capacity, heavy recoil, and slow rate-of-fire leave precious little room for error. A small combat load and the relative scarcity of ammunition available for the weapon also make it bad practice to expend ammunition on smaller, less threatening combatants, such as Grunts. The SRS99 series is also largely ineffective against most Flood forms, due to their body organization; damage done by the SRS99 series/Gameplay is minimal to the Flood forms due to their biological constitution and would only cause the Flood form to flinch for a moment. It is often recommended for operators to simply switch to other weapons should they encounter a Flood form.
As in all previous games, rounds fired by the SRS99 series leave a trail that could be traced back to the sniper's location. When using the scope, the glare from the reflection will be visible to the enemy and may alert them to your presence. The rifle is ineffective against even light-skinned and unarmored vehicles unless a shot can be taken on the vehicle's occupants, except for Wraiths.
