==Overview==
===Design===
{{Main|SRS99 Series}}
The SRS99D-S2 AM is a powerful, semi-automatic sniper rifle chambered in the [[14.5×114mm|14.5×114mm cartridge]], generally firing APFSDS (armor-piercing fin-stabilized discarding-sabot) ammunition.{{Ref/Reuse|ENC325}} The optic mounted on the weapon is capable of x5 and x10 magnification.<ref name="H3">[[Halo 3]]'', gameplay''</ref>

In profile, the SRS99D-S2 AM bears clear resemblance to the [[SRS99C-S2 AM]], sharing its smooth and simplistic design. The weapon's finish is matte grey. The charging handle is located on the left side of the weapon, a metallic-coloured rounded protrusion, and expended casings are ejected on the right. The stock is solid, and not connected with the pistol group as in some SRC99C-S2 AM rifles. A metal guard projects out from the underside of the weapon, over where it is gripped for firing. As in the SRS99C-S2, a square carrying-handle is located in front of and over the scope.{{Ref/Reuse|H3}}

===Performance===
The SRS99D-S2 AM is effective out to 4,920&nbsp;ft (1,500 metres), and has the capacity to eliminate targets in a single shot.{{Ref/Reuse|ENC325}} According to [[Roland Huffman|Major Roland Huffman]], a retired [[UNSC Marine Corps|UNSC marine]] with experience as a sniper, a shot fired from this weapon could penetrate "about 13 feet of flesh and bone" when fired from a distance of 600 yards.{{Ref/Reuse|Enemy}} Recoil is not considered a significant issue when employing this weapon, and its high rate of fire and ergonomic reloading process mitigate the limited capacity of the 4-round detachable box magazines utilized with it.{{Ref/Reuse|ENC325}}

===Development History===
[[File:HaloArmsRace4.JPG|thumb|220px|SRS99D-S2 AM sniper rifles being assembled at [[Misriah Armory]] on [[Mars]].]]
The SRS99D-S2 AM was developed by [[Misriah Armory]], with a line of them being manufactured on [[Mars]].{{Ref/Reuse|HLHAR}}

===Usage===
These rifles were notably employed by the [[UNSC]] in the latter stages of the [[Battle of Earth]], including by [[Orbital Drop Shock Trooper]] [[T. Rymann|Corporal T. Rymann]] during the [[Battle of Sector Six]].<ref>''[[Halo: Landfall]]''</ref>{{Ref/Reuse|H3}} These weapons played a role in the [[Battle of Installation 00]] as well, with [[John-117]] deploying with one during landfall in the [[Battle of Installation 00]].<ref>''[[Halo 3]]'', [[The Ark (level)|campaign level "The Ark"]]</ref> In [[2553#January|January, 2553]] on [[New Llanelli]], during one of [[Kilo-Five]]'s weapon transactions with [[Avu Med 'Telcam]], [[Orbital Drop Shock Trooper]] [[Malcolm Geffen|Staff Sergeant Malcolm Geffen]] was positioned on a ridge to cover the transaction, armed with an SRS99D-S2 AM.{{Ref/Reuse|HGC5}}

===Legacy===
At least two of these rifles were kept in the "Weapon room" of the [[Museum of Humanity]].<ref name="Enemy">[https://www.youtube.com/watch?v=Rz_7WWO8lXE ''Youtube'', Halo: 3 Belive: Enemy Weapon]</ref>

==Gameplay==
{{Main|Sniper Rifle}}
The Sniper Rifle is a [[Precision weapon|precision]] [[power weapon]], which fires highly damaging projectiles at near instantaneous speeds. It features two levels of zoom, and a magazine of 4 rounds. This makes it a powerhouse at long ranges, capable of killing most enemies, including enemy players in multiplayer, with one headshot, and outranging other weapons like the [[Battle Rifle]] significantly. To compensate for its power, it is a relatively rare weapon, and ammo for it is difficult to find.

==Trivia==
{{Linkbox|gameplay=yes|gallery=yes}}
*When meleeing with the weapon, the image on the scope will briefly reflect the player's field of view before switching to the scope's view.
*When throwing a piece of equipment, the player character's model will appear to sink into the rifle and disappear until the throwing animation is finished.
*The SRS99D's in-game model lacks the cyan "trinity" emblem seen on the sniper rifles in ''Halo: Combat Evolved'' and ''Halo 2''. However, it is shown with this symbol in ''Halo: Landfall''.
