"What the hell am I supposed to do with this inside a Covenant ship?"

- Kojo Agu

The Sniper Rifle System 99D-S2 Anti-Matériel, abbreviated SRS99D-S2 AM, and shortened to 99-D, 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.

Specifications
The SRS99D-S2 AM is a semi-automatic 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 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.

Development History
It was developed by Misriah Armory, with a line of them being manufactured on Mars.

Usage
In January, 2553 on New Llanelli, during one of Kilo-Five's weapon transactions with Avu Med 'Telcam, Malcolm Geffen was positioned on a ridge SRS99D-S2 AM to provide overwatch for the transaction, targeting 'Telcam's head.

Trivia

 * 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.
 * In-game, the spent brass from the weapon's firing is ejected out of the opposite side of the weapon from the port. This production error more likely pertains to the model itself than the animation, as most weapons are configured so that the brass ejects off to the right to minimize interference with more common right-handed shooters.
