The mobile artillery served as a weapons platform utilizing repulsorlift technology, and was employed by the forces of the Galactic Empire.

This mobile artillery unit was comparatively small, and its projectile cannon was primarily designed for use against enemy infantry, as it struggled to inflict significant damage on heavily armored vehicles. It functioned, in certain respects, as the ground-based equivalent of the AT-AA, engaging targets on land while the walker dealt with airborne threats.
Despite its vulnerability, the mobile artillery possessed considerable speed and could rapidly bring its primary weapon into action. This involved initially extending forward and sideways stabilizer beams, lowering itself to the ground, and then elevating its main turret.
These artillery units were transported to combat zones via Sentinel-class landing craft. They frequently operated in conjunction with larger artillery platforms, for example the heavy artillery repulsorcraft.
A different iteration of the heavy artillery consisted of a heavily protected, but slow repulsor platform equipped with a pair of substantial cannons.
