The crawler was revered for it's high rate of fire, and was said to be suicidal to fight just one AAC without an entire squadron of starfighters. The New Republic also had some cases of reusing Empire era AACs. Soon, many criminal organizations had bought these through the black market, and used it as tools to fight New Republic task forces that threatened important deals or markets. The slogan 'The X-Wing Killer' was used to sell the already pre-made 5,000 AACs to the Galactic Empire, which was bought extensively after The Battle Of Yavin and other Rebel attacks. Used by almost every government, mercenary force, and criminal organizations, it was the first product sold by Craester & Company and kidnapped Kuat Drive Yards employees. The Craester-class Anti-Air Crawler, also known as the AAC, 'Starfighter Squadron Annihilator' or the 'X-Wing Killer,' was a treaded vehicle used specifically as anti-air units.
