From the Movies

As the Clone Wars escalated, the Republic military built up their ground forces with newer, more versatile models of walking battlefield armor. This two-legged model, dubbed the pod attack walker, featured artillery cannons and a third retractable leg used for stability during long-range weapons firing. Clone trooper drivers piloted this walker model in such heated campaigns as those found on Kashyyyk and Felucia.

From the Expanded Universe

A larger iteration of the successful All Terrain Personal Transport (AT-PT), the All Terrain Attack Pod scaled up much of those systems into a two-man model. Though still too small to be deployed on its own, the AT-AP nonetheless transforms battlefield infantry into mobile medium-range artillery.

The adjustable suspension system gives the AT-AP walker stability and maneuverability over uneven terrain. The third leg lowers in the event of uneven terrain, or when the centrally fixed heavy projectile cannon fires.

The top-mounted swivel blaster has a gunner's saddle, and is best operated by a third clone trooper, seated outside the walker's armored cabin. Behind the saddle is a supply cage filled with tools to repair mechanical malfunctions within the walker's articulation assembly. Slung beneath the walker's cabin is a pivot-mounted medium laser cannon.

Behind the Scenes

The AT-AP walker was developed relatively late when the film was in postproduction. It was part of Lucas' request to diversify the clone ground armor. The initial concepts, developed by artist Alex Jaeger, were called the Pod Attack Walker, or P.A.W.
