The Fuel Rod Cannon is a Covenant heavy weapon used by their vehicles as a heavy weapon. Banshees, Anti-Air Wraiths, and Scarabs have all been seen using this weapon. It is a vehicle-mounted version of the infantry issue Fuel Rod Gun. The Banshee's version of the weapon can only fire one shot before reloading, but it makes up for this with its virtually unlimited ammunition. The Halo 3 Scarab has also been seen firing volleys of Fuel Rod shots as a defense mechanism.
