The AAT-40 was a one man, infantry support vehicle. Originally designed as an air defense artillery vehicle, the AAT-40 was more commonly used in the infantry support role. Its five barrel version of the venerable M61 Vulcan Gatling cannon fired 20mm HEAT/F rounds with laser-terminal guidance. The terminal guidance was very necessary, as the cannon had no ability to traverse.

AAT-40 3The AAT-40 was perhaps the most flawed vehicle design of the Robotech era. The main cannon had no traverse, which severely limited its effectiveness in the anti-air role (even with terminal guidance). It suffered from poor ground clearance, which limited its off road capabilities. With a crew of one, the AAT-40 could not engage targets while on the move as it had no dedicated gunner. Lastly, unless the rocket propelled grenade launcher was removed, the vehicle could not carry enough ammunition to feed the M61/5 long enough for sustained fire.
