Scorn Mine Launcher
From Destinypedia, the Destiny wiki
This drum-fed Grenade Launcher rapidly fires tracking grenades which continually bounce until it is within the vicinity of an enemy, where it explodes with Arc Energy. Direct hits by these grenades can be devastating. These weapons are used by Major and Ultra Scorn enemies, and some Chieftains, where they use it as a tactical mortar to keep their enemies on their toes.
