Clone wars - AT-AP in Massive Assault

The All Terrain Attack Pod, also referred to as the AT-AP self-propelled artillery walker and nicknamed the "sniper tank," was a tripedal pod walker used for long-range artillery strikes by the Grand Army of the Republic during the latter part of the Clone Wars. During the Galactic Civil War, they were used by the Alliance to Restore the Republic and the Galactic Empire.

The AT-AP's primary weapon was a powerful long-range heavy mass-driver cannon that was located in the forward hull. The cannon launched a solid durasteel penetrator at hypersonic speeds over extreme distances, and was able to strike targets beyond visual range with proper targeting data. In order to keep the cannon accurate and precise, the AT-AP was equipped with a sophisticated targeting and data-relay suite that worked in conjunction with integrated recoil compensation and gyrostabilization systems.
