There was a reason Linda and Johnson were armed with M99 mass-driver sniper rifles instead of the MA5Cs that everyone else carried. The M99s used magnetic accelerator technology to fire undersize ammunition at velocities so high that the rounds created shockwaves as they passed through their targets. The rounds might not be able to pierce a Covenant fighter’s energy shield, but they could penetrate thirty centimeters of titanium armor, and in the vacuum of space, their range was limited only by the accuracy of the person firing.
