The Armored Assault Tank (AAT-1 or AAT) was a medium-sized repulsor tank used mainly by the Axis of Empires. The tank had heavy frontal armor that gave it the capability to plow through walls, and it was heavily armed with a payload of 57 shells. The tank required a crew of four battle droids to be fully operated and was able to carry six additional battle droids onto the battlefield. The tank's reactor and power and communications gear were kept in the rear for protection.
The Armored Assault Tank was a formidable vehicle; it was augmented with heavy inches-thick frontal armor that allowed it to plow through walls, and had heavy weaponry. It carried a payload of 57 shells, but once these were exhausted, the AAT had to return to its carrier to have its shovel-shaped lower hull completely replaced, fully replenishing its supply.
The AAT's launch tubes could be equipped with a variety of ammunition. The three standard-issue ammunition types were "bunker-busters", high explosive shells used for destroying enemy structures such as outposts; armor-piercing shells, used for penetrating heavy armor on tanks; and high-energy shells for anti-personnel and anti-vehicle use. As they were fired, these shells were surrounded by high-energy plasma, which improved their penetration and reduced friction, thus increasing speed.
