Unlike the [[M512 smooth-bore high-velocity cannon|M512 cannon]] mounted on the M808, or even the [[M310 smooth-bore high-velocity cannon|M310 cannons]] mounted on the [[M850 Grizzly]], the M990 fires a much larger 150mm shell, and is capable of firing guided munitions and projected future advances in energetic propellants. ONI-operated Scorpions use an experimental shell, and [[Hannibal Weapon Systems]] has produced a prototype that uses a [[directed-energy weapon]] mounted within the barrel. | |||

The M990 is extremely effective at penetrating heavy armor, including {{Pattern|Kemu|Wraith}} tanks, and even Forerunner weapons such as the [[Z-510 focus turret]]. It is less effective against nimble aerial targets, such as the {{Pattern|D'nomlhe|Banshee}} or the [[Phaeton]], but is still easily capable of penetrating their armor. | The M990 is extremely effective at penetrating heavy armor, including {{Pattern|Kemu|Wraith}} tanks, and even Forerunner weapons such as the [[Z-510 focus turret]].
