The AAC-1 speeder tank functioned as a military landspeeder utilized by the Alliance to Restore the Republic throughout the duration of the Galactic Civil War.
Possessing both speed and exceptional lateral agility, the AAC-1 speeder tank could readily evade incoming enemy fire by slipping sideways. Despite having reinforced hull plating, its vulnerability was the black coolers positioned on the tank's flanks. Its principal armaments consisted of forward-facing laser cannons along with particle cannons, which could obliterate an enemy tank with only a handful of shots. Two rapid-firing missile turrets were installed atop the vehicle. The pilot operated the laser and particle beam cannons, while the gunner discharged the missile turrets. Functioning as an anti-aircraft combat vehicle, the speeder tank was propelled by a repulsorlift engine.
The AAC-1 originated as a prototype concept by the SoroSuub Corporation that ultimately never entered mass production. To settle gambling debts from a night of Sabacc, a SoroSuub designer sold the design schematics to operatives working for both the Alliance to Restore the Republic and the Royal Naboo Security Forces. The Alliance to Restore the Republic discovered the vehicle's effectiveness when deployed in quick strikes targeting enemy military installations.
During the Galactic Empire's assault on Naboo in 18 BBY, the Royal Naboo Security Forces made use of AAC-1s, during which Queen Apailana met her death. Around 0 BBY, during the Empire's raid on the Polis Massa base in search of the Death Star plans, both the Alliance and the Empire had AAC-1s stationed there.
A related model, the AAC-2 hovertank, was deployed by the Rebels in engagements such as the strike on Yavin 4.
This vehicle replaces the Rebel combat speeder from Star Wars: Battlefront, and the two share the same backstory.
