All Terrain Anti-Aircraft

The All Terrain Anti-Aircraft (AT-AA) was a quick-moving, quadrupedal, mobile anti-aircraft walker used by the Galactic Republic.

Characteristics
The AT-AA had four stubby legs and lizard-like locomotion, along with a low profile.

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.
