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

Main article: SRS99 Series

The SRS99D-S2 AM is a semi-automatic, gas-operated sniper rifle that fires 14.5mm x 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 187.5cm long and is completely modular.

The SRS99D has some notable changes from the SRS99C models. First off, it is fitted with a 5x and 10x 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.

Gameplay tactics

Main article: Sniping

Campaign

In the mission Sierra 117, there is a downed Pelican at Rally Point Alpha. There is a UNSC supply box with two sniper rifles. These can be useful when you get to the dam.
After the Hunter encounter on The Storm where you must face a hammer wielding Brute Chieftain the room to the far left contains a sniper rifle. Breaking the window will allow you to snipe Covenant forces.
Because the sniper rifle is extremely powerful, but has a small combat load, it is not good practice to use this weapon against weaker enemies (i.e. Grunts, Jackals). However, the sniper rifle's penetration capabilities and superb, long range accuracy make it excellent for killing higher ranking enemies at long range like Brutes and Hunters, which, in turn, disorganizes and demoralizes the enemy troops, making combat against a large ground force easier.
Sniping fallen grenades when enemies are close by is also an effective strategy.

Multiplayer

If an enemy will be very difficult to snipe, don't waste a round on them. Wait until they're an easier target, or just switch your attention to another target.
Have a sniper set their sights on the enemy base in a CTF match, as they can take out enemy snipers and other defenders. That way, their team mates can swoop in and grab the flag.
If you can get a couple of players to cooperate, you can get to hard to access areas on maps like Valhalla, Longshore and Last Resort and snipe without worry that close range weapons like the shotgun flush you out.
The Sniper Rifle shot can be used in close combat as a shield remover, followed by a melee which will kill your opponent.
Always take your shots carefully with the sniper rifle. If you are unable to perform headshots, always aim for the body. The key to sniping is simply getting the kill, not getting a headshot every time.
Always carry a secondary close ranged weapon such as an Assault Rifle or SMG. Even more preferable are a shotgun or a Battle Rifle.
When playing Team Snipers, take your shot and then move elsewhere, so your location is not given away.

Trivia

Unlike the SRS99C-S2 AM Sniper Rifle, the more recent sniper rifles lack a night vision function. This may be because of the differences in the weapon or because this version is not intended for use at night.
When you melee the rifle, the LCD screen, if watched a second before it stops moving, will still be pointing the direction you're facing, not where the scope is facing.
The max range of the scope's range-finder is approximately 275m. The max distance the reticule will turn red on enemies is approximately 142m.
The Laser Designator uses the SRS99D's stock and handle/grip in the production of Halo: Landfall.
When throwing a piece of equipment, such as a Tripmine or Power Drain, the biped will appear to sink into the rifle and disappear until the throwing animation is finished.
In Halo: Combat Evolved and Halo 2, a cyan logo identical to the "trinity" emblem can be found on the stock of the Sniper Rifle System 99C-S2 AM. However, in Halo 3, the emblem is absent from the SRS99D. In part 1 of the Arms Race video trilogy, the SRS99D can be seen being made at Misriah Armory on Mars. However, the "Trinity" logo is seen on the rifle in the Halo 3 game booklet as well as in the Arms Race Part 1, where it is found on the stock of the "second" rifle in the magazine, and in part 3, it is visible on the stock of the rifle when T. Rymann uses it to kill the Brutes.
