The AV-7 Anti-vehicle Artillery Cannon, also known as the AV-7 antivehicle cannon and more commonly known as the heavy cannon, was a model of self-propelled artillery cannon that the Galactic Republic used during the Clone Wars. Once it was moved into position with its repulsorlift feet, a single clone trooper could operate the cannon using the gunnery controls on the side of the central assembly.
