All Terrain Anti Aircraft/Legends

The All Terrain Anti Aircraft (AT-AA) was a quick-moving, quadrupedal, mobile anti-aircraft walker used by the Galactic Empire.
==Characteristics==
The AT-AA had four stubby legs and lizard-like locomotion, along with a low profile not seen in other Imperial walkers. On most models, the only weapon was a turreted flak pod, capable of firing several types of ordnance. Other versions could be equipped with one or three rocket-launching tubes. Initially the AT-AA had an inability to fire at ground targets. This was partially rectified with the addition of gun ports to allow the crew to fend off infantry attacks.
Some variation had flak pods replaced with concussion missile launchers. The AT-AA also carried electronic countermeasure systems that could scramble missile guidance systems, thus lowering the risk of missile strikes.
==History==
Its preliminary designs were developed as far back as the Clone Wars, and the design began production early on in the time of the New Order. The walker saw action during the Galactic Civil War, where it was used against aircraft, but was useless against any ground vehicles. Although the troopers aboard could fix blaster rifle mounts on the vehicle, the AT-AA still relied heavily on escorting infantry vehicles, including AT-STs.
During the Battle of Kalaan, AT-AA batteries protected the armored columns from airborne enemies, bringing down scores of Alliance T-47 airspeeders.Star Wars: Force Commander
AT-AAs were used even in the time of the New Republic, where they defended the galactic capital from the New Republic Defense Force.Star Wars: Galactic Battlegrounds: Clone Campaigns
