A fictional manned giant robot from the Gundam mechaverse.
MS-06K Zaku Cannon
A long range artillery support Zeon MS built upon the frame of the venerable Zaku II. It possessed a 180mm gun mounted upon its backpack and slung over its left shoulder, rooughly equivalent to the ones on the Guntank and able to destroy enemy MS in a single well placed shot.
Some units were equipped with the "Big Gun" missile launchers, fired from the waist, and sported twin radio antennae on the head - those units were called "Rabbit Types".
