The MK.78 is a full-auto light machine gun in Call of Duty: Black Ops 7, available in the base launch roster. Sources describe it as offering great damage and a high ammo count while being limited by slower mobility and handling. It is unlocked from the start, so it serves as the game's introductory LMG for sustained-fire support play.

How to unlock: The MK.78 is available immediately from the start of Black Ops 7 with no level, challenge, or mission requirement; it is the first light machine gun players have access to.
