The AV-7 Antivehicle Cannon, also known as the AV-7 Mobile Cannon, the Republic Artillery Gun, the heavy cannon, or the Clone Artillery Cannon, was a self-propelled artillery unit used by the Alliance of Nations. The vehicle could be operated by one tank gunner in a seat on the side of the gun, and had a chamber for refilling plasma shells to the side of the lower chassis.

The vehicle would be moved with its built in repulsorlifts until it reached a suitable firing position and then entrench itself on the ground, using four metallic feet for support.

Its artillery shells created a fairly large blast radius, able to take out both vehicles and surrounding droids in a single shot.
