The '''M99A2S3 Special Application Scoped Rifle''' is a weapon in the [[M99 Stanchion]] series of high-powered anti-materiel rifles in the service of the [[United Nations Space Command]].{{Ref/Reuse|CF100}}


The '''M99A2S3 Special Application Scoped Rifle''', also referred to as the '''M99A2S3 Stanchion''' is a variant of the [[M99 Stanchion]] created on the {{UNSCShip|Spirit of Fire}} by [[Isabel]].<ref name=cf100/><ref name=breakdown/>
==Overview==
[[File:HW2_Sparks.png|thumb|left|250px|An M99A2S3 Stanchion in use by [[Devon Sparks]], the sniper for [[Sunray 1-1]].]]
===Design details===
The Stanchion is built on a frame similar to that of the [[SRS99-AM sniper rifle]]. Unlike the SRS99, however, the Stanchion is a [[coilgun]], and has more in common with [[Gauss cannon]]s and larger [[Naval autocannon|naval guns]] in terms of operation than a regular firearm. The weapon is powered by an Asychronous Linear Induction Motor (ALIM), capable of accelerating its munitions to several thousand metres per second.{{Ref/Reuse|Enc22}} Accordingly, the receiver and barrel of the Stanchion are much bulkier than a conventional sniper rifle, with a protective housing visually reminiscent of the [[ARC-920 railgun]]. The Stanchion is renowned for overpenetration and collateral damage, making it extremely effective against its targets. The high muzzle velocity of the weapon makes it extremely powerful and accurate at long distances.{{Ref/Reuse|Enc22}}
 
Midway down the barrel, the M99A2S3 is located with an inertia buffer designed to help lessen the recoil produced when firing the weapon.{{Ref/Twitter|JeremyCook3D|950592593376628741|Jeremy Cook|Quote=Think hightec recoil management.|D=30|M=01|Y=2024}} The fore of the rifle features a bipod that can be folded back and secured on the weapon. The rifle is compatible with an [[ATLAS HISHOT PRO-X]] optic, capable of being [[Smart-linking|smart-linked]] with an operator's [[heads-up display]].{{Ref/Reuse|CF100}}{{Ref/Reuse|breakdown}}


==Design and development==
Unlike the standard M99 Stanchion rifle, the M99A2S3 does not appear to require an external [[generator]] to power the weapon. As such, this leaves the operator free to move around the battlefield rather than stay anchored to one shooting location. Likewise, the M99A2S3 does not appear to require the use of an external targeting computer.{{Ref/Game|HW2|Sunary 1-1 in-game unit}}
===Design details===

The rifle is compatible with an "ATLAS HISHOT PRO-X" smart-link optic.<ref name=cf100/><ref name=breakdown/>


===Ammunition===
===Ammunition===
The weapon has a feed of 7 rounds. These rounds are penetrator darts that are covered in a Sabot, and Storage casing which is "full burn-up".<ref name=breakdown/> While there is no official statement on bullet caliber, due to the ammunition comparison to the SRS-99's 14.5x114mm rounds <ref name=breakdown/>, we can assume that it is approximately a 18.125x129.2mm round, but a more reasonable assumption for ease of labeling would be 18x129mm.
The Stanchion fires [[tungsten]] penetrator darts, with a muzzle velocity of several thousand metres per second.{{Ref/Reuse|Enc22}} The darts are stored in a disposable burn-up casing that contains a [[Wikipedia:Sabot (firearms)|sabot]] and the dart itself. The weapon's detachable box magazine is capable of holding 7 rounds before a reload is required.{{Ref/Reuse|breakdown}}

===Development history===
The M99A2S3 was developed on the UNSC ''Spirit of Fire'' in its manufacturing block "23-CELL 14". It is based on a template by Isabel called "Isabel-2558-01-00023".<ref name=cf100/><ref name=breakdown/>
Developed and manufactured by [[HRN]],{{Ref/Reuse|TweetHRN}} M99A2S3 Stanchions are also capable of being manufactured aboard the {{Class|Phoenix|colony ship}}'s internal factory modules.

Overview

Design details

The Stanchion is built on a frame similar to that of the SRS99-AM sniper rifle. Unlike the SRS99, however, the Stanchion is a coilgun, and has more in common with Gauss cannons and larger naval guns in terms of operation than a regular firearm. The weapon is powered by an Asychronous Linear Induction Motor (ALIM), capable of accelerating its munitions to several thousand metres per second.[5] Accordingly, the receiver and barrel of the Stanchion are much bulkier than a conventional sniper rifle, with a protective housing visually reminiscent of the ARC-920 railgun. The Stanchion is renowned for overpenetration and collateral damage, making it extremely effective against its targets. The high muzzle velocity of the weapon makes it extremely powerful and accurate at long distances.[5]

Midway down the barrel, the M99A2S3 is located with an inertia buffer designed to help lessen the recoil produced when firing the weapon.[6] The fore of the rifle features a bipod that can be folded back and secured on the weapon. The rifle is compatible with an ATLAS HISHOT PRO-X optic, capable of being smart-linked with an operator's heads-up display.[2][3]

Unlike the standard M99 Stanchion rifle, the M99A2S3 does not appear to require an external generator to power the weapon. As such, this leaves the operator free to move around the battlefield rather than stay anchored to one shooting location. Likewise, the M99A2S3 does not appear to require the use of an external targeting computer.[7]

Ammunition

The Stanchion fires tungsten penetrator darts, with a muzzle velocity of several thousand metres per second.[5] The darts are stored in a disposable burn-up casing that contains a sabot and the dart itself. The weapon's detachable box magazine is capable of holding 7 rounds before a reload is required.[3]

Development history

Developed and manufactured by HRN,[1] M99A2S3 Stanchions are also capable of being manufactured aboard the Phoenix-class colony ship's internal factory modules. In 2558, the Smart AI Isabel created a design template for the weapon on the Ark, given the code "ISABEL-2558-01-00023". This design template was later put to manufacture following the arrival of UNSC Spirit of Fire to the installation in 2559, with Stanchions built in manufacturing block 23-CELL-14.[3]

Usage

During the Second Ark Conflict, the M99A2S3 Stanchion was used by Lance Corporal Devon Sparks of Sunray 1-1, and had achieved at least 17 kills with it. Sparks also customized his weapon with tally marks for every kill, a Dazzle camo pattern, and two charms; a Scorpio charm and an ODST Talisman.[2] During a mission on Arcadia in 2560, August-099 of Omega Team was equipped with an M99A2S3 Stanchion.[8]

In-game information

Halo Wars 2

The Stanchion features in Halo Wars 2 as a weapon that can be equipped by UNSC Sniper units. By default, snipers in Halo Wars 2 do not equip Stanchions by default but instead use integrally-suppressed anti-materiel rifles more in line with a conventional ballistic rifle. The Stanchion sniper rifle is the second upgrade available for the Snipers and can be purchased for a cost of Supplies 0, Power 750.

The M99A2S3 Stanchion rifle is used in the Operation: SPEARBREAKER expansion for Halo Wars 2 as a unique weapon equipped by Devon Sparks, the sniper of Sunray 1-1. Sunray 1-1 (and by extension, the Stanchion) only feature in the levels Gatecrashers and Not on My Watch.

Halo Infinite

The M99A2S3 Stanchion is useable in Halo Infinite as a cosmetic weapon model introduced in Content Update 29. The weapon can be applied as a cosmetic appearance for the SRS99-S7 AM sniper rifle, and features no gameplay/mechanical changes.
