The AT-AA was a quick-moving mobile anti-aircraft weapon platform that saw Imperial service some time before the Battle of Yavin. Unfortunately, two significant weaknesses plague the AT-AA. It is only capable of attacking aircraft and it has no means to protect itself against ground based vehicles. Compounding those problems is the AT-AA's weak armour protection. Nonetheless, the AT-AA remains an extremely powerful anti-aircraft platform. Although the design is vulnerable to both ground and air based attacks, it is the scourge of Rebel aircraft.
