The MQ-27 Dragonfire or Quadrones is an unmanned flying drone featured in almost all of the futuristic missions in Call of Duty: Black Ops II, as well as a usable drone in Strike Force missions and multiplayer matches. After taking enough damage, it falls to the ground and explodes; the resulting explosion is not lethal. In campaign, the Dragonfire is named Quad.
In campaign missions, only in "Achilles' Veil" a swarm of Quads drones would be temporarily assigned to David Mason, in others it can only be acquired via accessing locked containers.
Along with the VTOL Warship and A.G.R., the Dragonfire's timer will continue when paused on Theater Mode.
There is the name "Charlene" etched in one of the rotors. The name "Charlene" is a reference to the demonstration of the Dragonfire by FPSRussia, a well-known weapon demonstrator and internet personality on YouTube.
