The M99 works on the same operational principles as other magnetic weapons such as [[mass driver]]s and [[Magnetic Accelerator Cannon]]s, albeit on a much smaller scale. This system works through using a series of electromagnetic coils (an asynchronous linear induction motor) rather than chemical propellants as a source of kinetic energy. The M99's weight and bulk limit the weapon's use to highly specialized long-range precision sniping roles.<ref>[https://www.halowaypoint.com/en-us/universe/weapons/railgun '''Halo Waypoint''': ''Railgun'']</ref> | The M99 works on the same operational principles as other magnetic weapons such as [[mass driver]]s and [[Magnetic Accelerator Cannon]]s, albeit on a much smaller scale.

The M99 can be used with a [[portable computer]] to provide the ballistic calculations necessary to engage long range targets. The rifle can also be integrated with other systems, such as [[ARGUS drone]]s for trajectory and ballistic data. The M99 also uses the [[ATLAS+]] system developed by [[Ohana Prescient Systems]]. | The M99 can be used with a [[portable computer]] to provide the ballistic calculations necessary to engage long range targets.

The 5.4mm/.21 caliber round is very small in comparison to most standard firearms of the era, but using the Gauss technology, the small rounds have the ability to rip targets apart, even through office buildings. | The 5.4mm/.21 caliber round is very small in comparison to most standard firearms of the era, but using the Gauss technology, the small rounds have the ability to rip targets apart, even through office buildings.<ref name="CHP"/> This is due to the high force imparted on the round via the Gauss acceleration method. The round creates shockwaves as it passes through the target. In the case of material targets, this is a minor explosion and the creation of structural fractures. In the case of personnel targets, it simultaneously rips apart and pulverizes the body around the impact area. Even hits in an extremity or near-misses can be deadly. | ||
The rounds have been known to have the ability to travel great distances without affecting the trajectory, delivering enough force to punch through [[instacrete]] pylons, blow a [[human]] apart, and continue on course through an abandoned parking lot. | The rounds have been known to have the ability to travel great distances without affecting the trajectory, delivering enough force to punch through [[instacrete]] pylons, blow a [[human]] apart, and continue on course through an abandoned parking lot. | ||

The M99 Special Application Scoped Rifle entered production in [[2491]].<ref name="HGN122" /> Production was ceased in [[2521]].<ref name="HGN122" /> Though it was used mainly for anti-matériel operations, the .21 caliber round (with a muzzle velocity of 15,000 meters per second) proved very effective against "soft" targets such as personnel.<ref name="CHP">'''Halo: Contact Harvest''', ''Prologue''</ref> | |||
In [[2502|March 2502]], then-[[Corporal]] [[Avery Johnson]] used an M99 Stanchion to [[Operation: KALEIDOSCOPE|assassinate]] [[Jerald Ander]], the leader of the [[Secessionist Union]] cell on [[Harvest]]. Johnson took the shot as the terrorist leader was driven by in an open-topped truck; Ander's head and upper torso were severed by the impact. | In [[2502|March 2502]], then-[[Corporal]] [[Avery Johnson]] used an M99 Stanchion to [[Operation: KALEIDOSCOPE|assassinate]] [[Jerald Ander]], the leader of the [[Secessionist Union]] cell on [[Harvest]].

However, Johnson's second target detonated a bomb inside a [[Jim Dandy]] restaurant, killing herself, three [[UNSC Special Forces#Naval Special Warfare|Special Warfare]] Marines, and 38 civilians.<ref name="CH"/><ref>'''Halo: Contact Harvest''', ''page 86''</ref> | ||
Snipers assigned to the {{UNSCship|Spirit of Fire}} continued to use the Stanchion as late as April [[2559]], as the ship had been lost in space for [[2531#Febuary|the past 28 years]].<ref>'''[[Halo Wars 2]]'''</ref> | |||

*The M99 shares its designation with the real-life Barrett Model 99 single shot sniper rifle, a derivative of the Barrett M107A1 anti-materiél rifle. | *The M99 shares its designation with the real-life Barrett Model 99 single shot sniper rifle, a derivative of the Barrett M107A1 anti-materiél rifle. | ||
* | *Using the following formula: ''K = m(v*v)/2'', a round with 30.757MJ of muzzle energy and a muzzle velocity of 15km/s would have a mass of 271.78 grams or .6 lbs. This apparent discrepancy can be accounted for in one or both of the following ways: | ||
**It can be assumed that the weapon is not normally fired at its highest-rated output, as repeated firings could lead to barrel deformation due to both the electromagnetic repulsion and friction-induced heat of the projectile traveling the length of the barrel. Even if fired at 75% of full output, a round will still overpenetrate obstacles and inflict catastrophic damage to soft targets. | |||
**The 5.4mm designation refers to the ''diameter'' of the round, not its length. With this in mind, it is likely that the round is significantly longer than it is wide & is composed of a super-heavy alloy such as depleted uranium, in order to further enhance its destructive potential by concentrating more mass in a smaller area, which would allow more kinetic energy to be delivered to the target. | |||
