Assault cannon

The Assault Cannon is a Covenant weapon which is used by the Lekgolo (or Hunters). Its ammunition comes in the form of incendiary gel tubes called Fuel Rod Cells which can be fired as bolts or a continuous stream. It is used to arm the Lekgolo centries of the Forerunner Dreadnought in the novel Halo: Contact Harvest. In the first Halo game, Halo: Combat Evolved the Lekgolo use a version of the Assault Cannon preferably referred to as the Fuel Rod Gun which would charge and then fire one bolt. In Halo 2 and Halo 3 we see the second variant of the Assault Cannon which fires in a continuous stream.

It is located on the right "arm" of the colony, built into the Lekgolo that make up the limb.
