M99 Stanchion

The M99 Special Application Scoped Rifle, also known as the M99 Stanchion Gauss-rifle is a United Nations Space Command ground firearm.

Operational Use
It was used by Corporal Avery J. Johnson during Operation: KALEIDOSCOPE (a mission where he used an M99 SASR to assassinate Jerald Mulkey Ander, a member of the Secessionist Union). It was also used during Operation: TREBUCHET by Johnson to stop a potentially dangerous Insurrectionist at a local restaurant on the planet Tribute known as the Jim Dandy.

Caliber and Technology
The M99 fires small caliber tungsten rounds, about 5.4mm, or .21 caliber. The M99 negates this by using magnetic forces over chemical propellants as a source of massive acceleration, similar to the operation of the M68 Gauss Cannon and on a much larger scale, the MAC Cannon. The rounds hit their target with an immense amount of kinetic energy. During an Operation: TREBUCHET mission Johnson fires and the round passes through a building and still has enough energy to blow the target apart. The weapon also appears to be able to use input from a laptop for ballistic calculations. It can also interface with other targeting and computer systems for trajectory calculations, such as the ARGUS Drone.
