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 is an [[Wikipedia:Electrothermal-chemical technology|electrothermal-chemical gun]], and is considered the single-biggest improvement on the M820 platform over its M808 predecessors.{{Ref/Reuse|Enc22}} | |||

The [[XM820B4 Scorpion]], an experimental model produced by [[Hannibal Weapon Systems]], uses the M990 ETC gun's hull and structure as a base for the integration of a fast-discharge [[laser]] weapon system. Aesthetically, this weapon has few outward differences than the standard M990, though is functionally a [[directed energy weapon]] rather than a conventional tank gun.{{Ref/Game|H5G|List of REQ cards|REQ Card|Detail=Hannibal Scorpion Description|Quote=This is but one of Hannibal Weapon Systems' tank test beds fitted with the latest in vehicle-borne directed energy weapons.

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. | |||
