The All Terrain-Attack Pod or more simply AT-AP was a three legged walker used by the Galactic Republic during the Clone Wars, armed with one ventral heavy repeating blaster, one dorsal medium laser cannon and 1 heavy mass driver cannon and utilizing its sophisticated targeting systems to provide long range artillery support with sniper levels of accuracy earning it the nickname of the "sniper tank". The AT-AP also had the capability of retracting or deploying its smaller forward leg for stability when travelling over hazardous terrain and to brace for the recoil of its weapons.
