This weapon can also be housed within a lightly armored protective housing for use with Mecha as a mounted weapon. Additionally, it can be modified with its own power source as well as a grip and trigger system for use as a handheld sniper rifle for Mecha.

(Type) Purpose
Armor Piercing Incendiary-Discarding Sabot Heavy armor piercing, damages shields through kinetic transfer and penetrates armor
High Explosive Anti Tank- Fragmentation Medium to heavy anti-armor, Overloads shields via explosives and damages armor. fragmentation causes area of effect damage to smaller targets
High Explosive Plasma Contained plasma charge does damage via explosions and armor ablation, very effective against most materials and shields

Weapon Mechanisms

Information about how the 125mm Gauss cannon functions

  • Firing Mechanism: A round is loaded into the chamber from the magazine and then pushed forward into the Gauss coils, which propel the round forward at high fractions of the speed of light. The coils and rails must be allowed to cool for several seconds before another round can be inserted, re-starting the cycle.
  • Loading: The 125mm Gauss Cannon is fed via a simple six-round Box magazine But can be modified to accept a belt-feed or autoloading system depending on how it is mounted.
